SQL Server 2016 Discovery Day – Data Visualization using R and Power BI.

SQL Server 2016 Discovery Day – Data Visualization using R and Power BI.

Last week we conducted the SQL Server 2016 Discovery Day –Release Event Kathmandu, Nepal successfully on July 9th 2016. SQL Server Launch 2016 Event and Discovery Day is a free, one-day event where individuals come together, learn about SQL Server 2016 and solve a pre-determined problem.

https://www.eventbrite.com/e/sql-server-2016-discovery-dayrelease-event-kathmandu-nepal-tickets-25888946536?aff=efbnreg#

I got a chance again to speak in this great event and it was fun and share knowledge along with other SQL Geeks, I had given presentation on

SQL Server 2016 Discovery Day – Data Visualization using R and Power BI.

You can find my slides using below link:

Also, we had a small solution development competition in the event where we use Power BI Desktop free tool in order to create some visualization and tell some story behind data.

Below is some quick visualization that I had created in the event by using PASS SQL Saturday real Data.

Steps for Making Data visualization by using Power BI Desktop.

Step 1: Firstly, download and install the Microsoft Power BI Desktop tool, which is free from the link below also for R related charts and play around with R codes we need to download R , RStudio IDE and install too. Below is link for Power BI Desktop, R, and RStudio IDE.

https://powerbi.microsoft.com/en-us/desktop/?gated=0&number=1

https://www.r-project.org

https://cran.r-project.org/src/base/R-3/

https://www.rstudio.com/products/rstudio/download/

Step 2: Get the data related to SQL PASS, SQL Saturday from the link below:

https://drive.google.com/file/d/0BzlPwGX6UtxUNnlfZ01KczF0NHc/view

This zip data files contains the different .sql files with data included within scripts.

Step 3: Load those scripts into SQL Server Database and then use Power BI Desktop ‘Get DATA’ tab to load the Data into Power BI Desktop and do visualization.

blog1

Alternative:  If you haven’t install the SQL server Database then you can use a single file such as ‘dbo.SQLSatSessions.Table.sql’ and then Excel file to manipulate the data in your required format.

Step 4: Load the only data part from the file ‘dbo.SQLSatSessions.Table.sql’ into excel as below

blog2

Then use Text to Columns tab in DATA tab section as below to make the data into proper column format.

blog3

Once you prepare your data as below format then now you can start analysis using Power BI Desktop.

blog4

Step 5: Use Power BI step 3 or Step 4 to load the data into Power BI. We have use step 4 here so now use Power BI to load data from Excel source then you will get data columns in right hand side as below.

blog5

Step 6:  Now start visualization using Power BI Desktop free tool, here we are using data of SQL Saturday session details and prepare different line chart, tree map, filled map , Table , R script Visual different charts that we have used to show different visualization details as below.

blog6

blog61

One can learn how to create these different charts by going through below links

https://powerbi.microsoft.com/en-us/documentation/powerbi-service-visualizations-for-reports/

Step 7: For now just for sample how we can simply create a line chart by just drag and drop feature of Power BI Desktop.

Just go to right side of Power BI Desktop and select EventDate and SQLSATURDAY filed and drop Eventdate in Axis and SQLSATURDAY into Values section and change the SQLSATURDY value as count by just clicking on SQLSATURDY field in Values section.

blog7Just simple so you can try these different charts by simply drag and drop feature.

For R script Visual you need to know some R language first in order to create R visualization chart in Power BI . One can learn R from https://www.r-project.org/

Step 8 :Publish these reports on Power BI cloud service by just clicking Publish button from Power BI Desktop , also now one can also publish these reports to publicly in web. Once you publish your report in Power BI service go to Reports -> Your Report -> File -> Publish to web . After that anyone can go through these reports publicly in the web.

Also, URL that you get through publish to web can be embedded to your website along.

Summary:

In Summary, from these above Power BI Desktop Visualization it helps to tells us that which SQL Saturday is conducted in which state, country in which year and a particular Day along with total sessions conducted. It also helps us to tell us that SQL Saturday trends year on year and mostly in September month most of SQL Saturday is conducted as per SQL Saturday data history.

Also, it helps to tell the distribution of state wise SQL Saturday conducted states .which shows most of SQL Saturday happens in North America.

How to Install Vertica in a single node.

Install Vertica in a single node. 

This article is mainly related to:

  1.  Setup of Vertica in a single node.
  2. Vertica Console Management
  3. Tableau
  4. DBeaver

During my free time, I want to try to install Vertica and want to know what it is all about. what are the things we should know while installing Vertica and what will be the issues, difficulties, requirements and process do we need to follow in order to setup Vertica and play around it.

The HP Vertica Analytic Database is based on a massively parallel processing (MPP), shared-nothing architecture, in which the query processing workload is divided among all nodes of the Vertica database.

If you want to try Vertica and play around along with this columnar database then you should follow below steps.

Step 1:

Firstly you should have any Linux OS installed in a machine. For Vertica, the minimum requirement is to have 3 nodes that mean’s three Linux OS running in different nodes. But, in my case I want to try to install in only one node and try it out. I have windows 7 OS install and where I have install Red hat Linux in my virtual machine. So, make sure you have at least one Linux OS installed machine.

You may find the below link to find out the minimum requirements and server configuration:http://my.vertica.com/docs/5.1.6/HTML/index.htm#18671.htm

General Platform Recommendations

  • ext4 is recommended over ext3 for performance reasons.
  • Use 2GB of swap space regardless of the amount of installed RAM.
  • Place the database /catalog directory on the same drive as the OS.

Step 2:

Download all the required software related to Vertica from the site https://my.vertica.com/downloads/

In order to download you can sign up in a community edition. All the stuffs you can know from below video:

http://www.vertica.com/files/myVerticaVideo/myVertica_Audio_Video_Combined_121009J.html

Here, I have downloaded the below versions:

Step 3:

After that move the setup files into Red Hat Linux virtual machine directory. I have put the setup files into directory as /data/software and then open the terminal in VM,

Run the below command as root user:

rpm -Uvh /data/Software/vertica-7.0.2-1.x86_64.RHEL5.rpm

Then after that it will ask to run the /opt/vertica/sbin/install_vertica to complete the installation.

Step 4:

Run the script in master node

# /opt/vertica/sbin/install_vertica -s host_list -r rpm_package -u dba_username

Here I used only one node so below is my script.

 /opt/vertica/sbin/install_vertica -s localhost -r /data/Software/vertica-7.0.2-1.x86_64.RHEL5.rpm -u dbadmin

Here, you need to note that if you want to install Vertica in multiple nodes then you can include different nodes or host list.

Where options are:

-s host_list comma-separated list of hostnames or IP addresses to include in the cluster; do not include space characters in the list.

  1. -r “vertica_6.0.x.x86_64.RHEL5.rpm”
  2. -u dbadmin user name
  3. -p dbadmin passowrd
  4. -P root password
  5. -L location of the license
  6. -d where data will be located
  7. -s nodes that will be part of the cluster
  8. -r location of the installation rpm

— If you omit the -u parameter, the default database administrator account name is dbadmin who will only use the admintools.

You can find more about installing vertica in 3nodes or complete cluster Installation in below link:

http://www.aodba.com/main_articles_single.php?art=83&page=vertica

Step5:

After that you will get some issues or errors as below which I have got

>> Validating node and cluster prerequisites…

Failures during local (OS) configuration for verify-127.0.0.1.xml:

Then go through each error in the link below

https://community.vertica.com/vertica/topics/

This is all about some cluster prerequisites. Here go through each FAIL(XXXX) in the community forum where you will get the solution for each error.

Step 6:

After that, run the admintools from the dbadmin user then you can see as

After that create the database:

Then choose the host name where database will reside:

Then, define the Catalog location and data path

Since I have installed Vertica in a single node so there will not be the concept of K-Safe method. If we are installing at least 3nodes then we can have k-safe.

After that,

Then create Vertica database as Vertica_DB in a single node.

After that the database will created.

 

Just click OK and you will see the Database configuration:

Then finally you can exit from the admintools:

Step 7:

Vertica management console:

After successful installation of Vertica Database now you can install the Vertica management console:

The new HP Vertica Management Console is an enterprise database management tool that provides a unified view of your HP Vertica database and lets you monitor multiple clusters from a single point of access.

You can find more on below link:

https://my.vertica.com/docs/5.1.6/HTML/index.htm#16773.htm

Run the command as a root user:

rpm –Uvh vertica-console-7.0.2-1.x86_64.RHEL5.rpm

After successful installation it will show URL as https://localhost.localdomain:5450/webui during the installation. Just go through the URL and accept the license

What you can do with Management Console

  • Create a database cluster on hosts that do not have HP Vertica installed
  • Create, import, and monitor multiple HP Vertica databases on one or more clusters from a single point of control
  • Create MC users and grant them access to MC and MC-managed databases
  • Manage user information and monitor their activity on MC
  • Configure database parameters and user settings dynamically
  • Access a single message box of alerts for all managed databases
  • Export all database messages or log/query details to a file
  • View license usage and conformance
  • Diagnose and resolve MC-related issues through a browser
  • Access a quick link to recent databases and clusters
  • View dynamic metrics about your database cluster

The features is so much helpful for the DBA’s and the developer from where they can easily monitor multiple HP Vertica databases on one or more clusters from a single point of control.

Detail setp to install and login setup process is shown in my slideshare , you can see the link below :

https://www.slideshare.net/anil_maharjan/how-to-setup-vertica-in-a-single-node

Tableau:

Tableau can help anyone see and understand their data. Connect to almost any database, drag and drop to create visualizations, and share with a click.

To know the story behind your data which is stored in Vertica DB, you need to have a reporting tool which can make a quick decision and helps you to get the value of your data.

This is where Tableau can be used. Which is one of the best Reporting Tool I must say.

One can go to Tableau portal and download the software and play around any database, Worksheets, excel files and so many other data files.

I have downloaded both desktop and public version of Tableau, and where as desktop version works for 15 days trail.

Now in order to connect Vertica DB through Tableau you need to install the Vertica client in your PC i.e. my windows 7 machine, where you need to download the vertica-client-7.0.2-1.64 from https://my.vertica.com/

Also, you can install the test db along with Vertica as VMART schema but in my case I am getting error so I have posted into Vertica community .One can join this community and can share ideas and issues.

https://community.vertica.com/vertica/topics/cannot-create-vmart-example-db

After that you can open tableau desktop and connect to Vertica DB in order to play around with and to find the story behind your data.

Also, you can have public tableau install in your PC and do some analysis using different worksheets, I have also done some analysis related to ‘Average Percentage of Internet Users across the World ‘ and published into public server which is free that Tableau providing for normal users.

https://public.tableausoftware.com/views/AveragePercentageofInternetUsersaccrostheWorld/AverageofIndividualsUsingtheInternet?:showVizHome=no#1

DBeaver:

DBeaver is free and open source (GPL) universal database tool for developers and database administrators.

  • Usability is the main goal of this project, program UI is carefully designed and implemented.
  • It is freeware.
  • It is multiplatform.
  • It is based on opensource framework and allows writing of various extensions (plugins).
  • It supports any database having a JDBC driver.
  • It may handle any external datasource which may or may not have a JDBC driver.
  • There is a set of plugins for certain databases (MySQL and Oracle in version 1.x) and different database management utilities (e.g. ERD

You can find more from the link :

http://dbeaver.jkiss.org/about/

I just found this tool so easy to connect with Vertica DB and do some queries analysis

Summary:

Through this article, I am sure you are now able to understand how you can install Vertica Analytic Database in a single node and how you can use Vertica Management Console to monitor multiple clusters from a single point of access. How you can easily get the story behind your data in Vertica DB by using the Tableau Reporting tool.

Also, how you can use quires to do more detail analysis by using the DBeaver tool in Vertica Database.

Cross joins across user defined hierarchies aren’t supported .?

Hello all,

It’s not appropriate to post as this a blog but it might help to most of us in field of BI having similar kind of confusion /issue.

I have some confusion on crossjoin function within MDx.

while I try to crossjoin the different level sets of same Hierarchy. It shows error as

For example.

‘The Customer Geography hierarchy is used more than once in the Crossjoin function.’

select {{[Customer].[Customer Geography].[Country].&[United States]}*

{[Customer].[Customer Geography].[State-Province].members}} on 0

FROM [Adventure Works]

WHERE Measures.[Internet Sales Amount]

Cannot we Cross joins across user defined hierarchies ,or they aren’t supported .?

Coz I really need to implement as above MDx within my real Cube.

I try to implement by making as another Hierarchy Member but it doesn’t gives the value result as what we want/need.

with member [Customer].[Country].[United States ]as [Customer].[Customer Geography].[Country].&[United States]

select {

{[Customer].[Country].[United States ]}*

{[Customer].[Customer Geography].[State-Province].members}} on 0

FROM [Adventure Works]

WHERE Measures.[Internet Sales Amount]

Though while looking on Adventure Works Cube ,it has attribute as Country, State-Province, and others along with the User define Hierarchy as Customer Geography with in a Customer Dim.

So while we crossjoin in the members of attribute of same Customer  dimension it gives result

SELECT

{      {[Customer].[Country].[United States]}*

[Customer].[State-Province].Members

} ON 0

FROM [Adventure Works]

WHERE Measures.[Internet Sales Amount]

But similarly, while we try to crossjoin with in the attribute members of user define Hierarchy from  Customer Geography it gives error.

Does that mean we need to create some dummy/hidden attributes for that particular dimension in other to obtain the solution for my case. ?-may be this is the solution

Does this mean we cannot crossjoin across user defined hierarchies?

It is just an example ,I simply need like this within from same user defined Hierarchy. By defining as user define calculated member of different attribute/dimension I am able to obtain the output as below but the values doesn’t valid or match.

with member [Customer].[Country].[United States ]as [Customer].[Customer Geography].[Country].&[United States]

member [Customer].[State-Province].[Alabama ]as [Customer].[Customer Geography].[State-Province].&[AL]&[US]

select

{Measures.[Internet Sales Amount]} on 0,

{{[Customer].[Country].[United States ]}*

{[Customer].[State-Province].[Alabama ]}*

{[Customer].[Customer Geography].[Postal Code].members}} on 1

FROM [Adventure Works]

Country State-Province Postal Code(Can be Top 10 members) Internet Sales Amount Other Measures
United States Alabama

Generate possible combination of MDx automatically by just pointing the SSAS cube Catalog.

Hello all,
After such a long time , I would like to post some another blog which might be helpful to the one who works in BI mainly in SSAS/MDx.
I simply need to generate some possible combination of MDx automatically by just pointing the SSAS cube Catalog.
In order to got my solution I had research a lot and also post the request in MSDN as well as BIDN forum and got some help through my MSDN post by Hari .
For getting the solution ,we simply need to create the SSIS package as below.
Following are the steps below.
1. Build new SSIS package and in data flow task.
2. Add script component with Source setting as the first task.
3. Paste the code shown in the code shown below. This code takes as input the SSAS server and Database name. This is iterate through the dimensions and base measures. For each base measure it identifies all the corresponding dimension. For each dimension it will identify the attribute which is mapped to the measure group and attribute directly relating to it. Output of this task is dimension, cube, attribute, basemeasure.
Note: Add the reference ‘ Microsoft.AnalysisServices.dll ’ in your code which can be found in the server where you have SSAS installed .i.e. C:Program FilesMicrosoft SQL Server90SDKAssemblies
String strCube, strDimension, strAttribute, strMeasure, strDatabase;
Server s;
CubeCollection cc;
MeasureGroupCollection mgc;
MeasureGroupDimensionCollection mgdc;
MeasureGroupAttributeCollection mgac;
RegularMeasureGroupDimension rmgd;
ReferenceMeasureGroupDimension rfmgd;
MeasureCollection mc;
strDatabase = “Adventure Works DW 2008”;//add catalog here
s = new Server();
s.Connect(“ANILMAHARJAN”);//add server here
cc = s.Databases[strDatabase].Cubes;
foreach (Cube c in cc)
{
strCube = c.Name;
mgc = c.MeasureGroups;
foreach (MeasureGroup mg in mgc)
{
mgdc = mg.Dimensions;
mc = mg.Measures;
foreach (MeasureGroupDimension mgd in mgdc)
{
strDimension = mgd.CubeDimension.Name;
if (mgd.GetType().Name == “RegularMeasureGroupDimension”)
{
rmgd = (RegularMeasureGroupDimension)mgd;
mgac = rmgd.Attributes;
}
else if (mgd.GetType().Name == “ReferenceMeasureGroupDimension”)
{
rfmgd = (ReferenceMeasureGroupDimension)mgd;
mgac = rfmgd.Attributes;
}
else
break;

foreach (MeasureGroupAttribute mga in mgac)
{
if (mga.Type.ToString() == “Granularity”)
{
strAttribute = mga.Attribute.Name;
foreach (Measure m in mc)
{
strMeasure = m.Name;
AttributeRelationshipCollection arc;
arc = mga.Attribute.AttributeRelationships;
int iFlag = 1;
GetRelatedAttribute(iFlag, strDatabase, strCube, strMeasure, strDimension, mga.Attribute);
}
break;
}
}
}
}
}
}
public void GetRelatedAttribute(int iFlag, String strDatabase, String strCube, String strMeasure, String strDimension, DimensionAttribute att)
{
String strAttribute;
AttributeRelationshipCollection arc;
arc = att.AttributeRelationships;
strAttribute = att.Name;
CubeMetadataBuffer.AddRow();
CubeMetadataBuffer.Database = strDatabase;
CubeMetadataBuffer.Cube = strCube;
CubeMetadataBuffer.Dimension = strDimension;
CubeMetadataBuffer.Attribute = strAttribute;
CubeMetadataBuffer.Measure = strMeasure;
iFlag = 0;

if (arc == null)
{
return;
}
else
{
foreach (AttributeRelationship ar in arc)
{
GetRelatedAttribute(iFlag, strDatabase, strCube, strMeasure, strDimension, ar.Attribute);

}
}

}
}
4.Add second script component with Transformation setting with coding as
String strCube, strMeasure, strDimension, strAttribute, strMDXQuery;
strCube = “[“+Row.Cube+”]”;
strDimension = “[“+Row.Dimension+”]”;
strAttribute = “[“+Row.Attribute+”]”;
strMeasure = “[Measures].”+”[“+Row.Measure+”]”;
strMDXQuery = “select nonempty(” + strDimension + “.” + strAttribute + “.” + strAttribute + “.members,” + strMeasure + “) on rows, {” + strMeasure + “} on columns from ” + strCube + “;” + “rn”; Row.MDXQuery = strMDXQuery;

5.Store those outputs within the table or any file for further propose and also we can add user calculated sets and Members within the MDXQuery. which can be very helpful for other purpose i.e. to capture performance statistics.
Snapshot of SSIS Package

Some output sample MDx Queries
select nonempty([Promotion].[Promotion].[Promotion].members,[Measures].[Internet Sales Amount]) on rows, {[Measures].[Internet Sales Amount]} on columns from [Adventure Works];
select nonempty([Promotion].[Min Quantity].[Min Quantity].members,[Measures].[Internet Sales Amount]) on rows, {[Measures].[Internet Sales Amount]} on columns from [Adventure Works];
select nonempty([Promotion].[End Date].[End Date].members,[Measures].[Internet Sales Amount]) on rows, {[Measures].[Internet Sales Amount]} on columns from [Adventure Works];
select nonempty([Promotion].[Start Date].[Start Date].members,[Measures].[Internet Sales Amount]) on rows, {[Measures].[Internet Sales Amount]} on columns from [Adventure Works];
Hope this post will be useful for all of us in the field of BI.

How to find a Calculated Measure and Calculated Dimension with in particular cube.?

Hello all,

After such a long time , I would like to post some simple tips for calculating the Calculated Measure and Calculated Dimension within a particular cube in SSAS.

Though it might simple but this help me a lot.

I simply need to list down the calculated measures within a particular cube for which I have to open the BIDS project and lookup how many calculated Measure that I had made and their names which seems little odd. So ,after some research and trying out DMV queries I finally got a simple way .

DMV:

Dynamic Management Views is introduced in Analysis Services 2008 and is used to track the server resources used .It can be queried like SQL –Like syntax. We can run DMV query in SQL server Management Studio in an MDX Query.

For Calculated Measure and Calclated Dimension Member and other entire details of Cube Catalog from SSAS.

SELECT * FROM $system.MDSCHEMA_MEMBERS

WHERE [MEMBER_TYPE] = 4

Refer some other DMV queries from the link

Load 1TB data in just 30 Minutes with SSIS

Today , I came to read some nice blog post by Microsoft regarding the data loading process.

If your company needs to load the maximum data then I think this post would be really helpful.
If you want to load 1TB data in just 30 Minutes with SSIS then.. Plz read this post by Microsoft.
http://msdn.microsoft.com/en-us/library/dd537533(v=SQL.100).aspx

since, the article was posted long time ago but might be helpful for the one who is just looking for this kind of approach.
Though ,I could not tried it out but sooner or later I would definitely like to test this process too.

Thanks,

Backup all SSAS databases automatically and schedually.

With the course of time, you might need to backup all the SSAS databases within a server instance automatically and schedule to backup these database monthly wise or according to your specific time set.

May be there are a lot of alternative methods to perform this task and many solution’s.

But I have researched a lot regarding to backup all the SSAS databases within a particular server instance.

In my last blog post I have shared “How to schedule and dynamically backup all the SQL databases within a server instance”.
Here ,I am going to show how to obtain all the cube databases backup automatically along with schedule time set.

These are the following steps you should have to follow.
1. Adding a linked server in SSMS.
You can simply add a linked server within a SSMS by using a script as
–Adding a linked server
EXEC master.dbo.sp_addlinkedserver
@server = N’SSAS_Backup’
, @srvproduct=N’MSOLAP’
, @provider=N’MSOLAP’
, @datasrc=N’ANILMAHARJAN’ /* <<< My Analysis Services server name */
/* <<< My Analysis Services database name */
go

–Setup security as per your environment requirements.
EXEC master.dbo.sp_addlinkedsrvlogin
@rmtsrvname=N’SSAS_Backup’
, @useself=N’False’
, @locallogin=NULL
, @rmtuser=NULL
, @rmtpassword=NULL
go

2. Make a SSIS package.
You can simply create the SSIS Package as shown in below

2.1. Create the table in SSMS of the output of all the catalog name within a server given by frying the query into the DMV in SSAS from SSMS.
You can use the following script in order to find all the current catalogs name within a server.
IF EXISTS(SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = ‘CubeBackupInfo’) DROP TABLE [CubeBackupInfo]
SELECT * into CubeBackupInfo FROM OPENQUERY(SSAS_Backup,’select * from $system.dbschema_catalogs’)

2.2. Read the total no of database backup to be made by reading the max count of catalog name from the table just we created above.

2.3. Read the backup XMLA within a variable into SSIS from a particular location.i.e backup XMLA that generated manually and we can also generate it by using a some C# or vb.net code embedded within SSIS.
Here is an XMLA script for backup
2.4. Now, within a for loop, set the max loop to the variable as @Max_No_Backup i.e max no of backup to be made.

2.5. Here read the catalog name of database with in a server one by one by using a table that we created before from CubeBackupInfo.
2.6 Modify the XMLA script using ‘Script Task’ within where I have used C# code in order to modify the XMLA and generate the modified XMLA for each catalog name one by one.

2.7. Backup all the cube database with in a server into a default location of SSAS backup.
-stores acc to the ‘catalog name’ along with the ‘system date’ in order to know the particular backup date. as i.e. TestCube-03-11-2011.abf
-also catalog name can overwrite it if it exist already.
i.e. : C:Program FilesMicrosoft SQL ServerMSAS10.MSSQLSERVEROLAPBackup

3.Make a SQL Server Job agent.
3.1. You can easily make a job in SQL by following this link http://www.sqlservercentral.com/articles/Stairway+Series/72267/
and Running and Scheduling SSIS Packages by following the link as http://www.sqlshare.com/running-and-scheduling-ssis-packages_53.aspx
4.Make schedule to backup all the catalogs/ database within a particular server. i.e. monthly or weekly according to your specific time set.

Hope this will help for someone , also I am thinking to post another blog about ‘Dynamic partition within a cube’ using a similar approach where I have researched a lot in this topic too.

OLAP PivotTable Extensions

Wow, I am so excited that there is such a cool extension available for the excel 2007 onwards ,firstly I don’t know that we can use this cool features add-in extension within an excel .I have often used the PivotTable but I never try it for this particular extension and its features.

I had bookmark for this particular page link a few months ago while I was doing my intern program but suddenly I check it back again now and I found why should not I had look the page clear fully before and why I had not use it or try it out before asking myself. 

But , nice to know that it has some great features like :
1. Private Calculated Members,
2. Calculations Library,
3. View PivotTable MDX,
4. Changing PivotTable Defaults,
5. Searching,
6. Distributing PivotTables

Among these I found the most useful and cool features is viewing entire MDx script and searching features.

Also as we know there are a lot of different tools/software’s that provides these facilities but one simple thing is that we can easily download this extension and it is free too.
You can visit the links as

How to schedule and automate backups of all SQL Server databases in SQL Server.

Hello all,

With the course of time, you might need to backup all the databases within a server instance automatically and schedule to backup these database monthly wise or according to your specific time set.

Also, what I want to say is that ,I cannot stop myself to write this another blog of mine.

writing a blog and sharing some knowledge through the blog makes us really feels happy and also somewhat we also become addicted to it. 🙂

This may be simply for one but for someone it will be helpful for those who don’t know how to do it.

May be there are a lot of alternative methods to perform this task and many solution’s.

But I have researched a lot regarding to backup all the SQL database as well the SSAS catalogs database backup with in a particular server instance.

Here ,I am going to show how to obtain the SQL database backup automatically along with schedule time set.
Firstly, I have created a SSIS package where I used simply “Back up Database Task “ from toolbox and click right then clicking in edit tab, we can set the connection as show in figure1 below:

Then we can set the Backup Type as full or other type after that you can select the databases to backup as show in figure2 below where we can set required databases to backup.

After that you can set the other different properties like
1.Backup set Expire
2.Bakup to
3.Append or overwrite if backup exist
4.for everyday backup options
5.Backup location directory currently I set to default location.
6.allow compression or not.
You can figure out by looking the figure3 below.

Now all you need to create a job agent to schedule the backup task and run SSIS package. In order to do this you can check out the link by Brian Knight as
http://www.sqlshare.com/running-and-scheduling-ssis-packages_53.aspx

or simply go to SSMS and start Sql Server Agent and right click and create new job where you have to setup some properties as shown in figure4.

Here you can schedule the backup going into the schedule tab and then just check the job working or not by right clicking it and Start job at step then you can check the all the backup database within the default location as : C:Program FilesMicrosoft SQL ServerMSSQL10.MSSQLSERVERMSSQLBackup

Hope you get some ideas to obtain the schedule Sql databases backup automatically ,also I am thinking to post into my another blog for “ Automate and schedule all SSAS catalogs database backup with in a server instance by using Job Agent” or similar approach which have taken most of my research time and I am happy to obtain the result successfully.

Lastly,this may be simple but I think it may work out for someone .

Thanks,
