SSIS Validation And DelayValidation
Validation And DelayValidation are one of the most confusing part of SSIS and hence widely misunderstood by SSIS developer. Though understanding these concepts are very essentials to understand what happens before runtime or pipline engine start executing the package.
I have written an article covering all aspects of SSIS Validation And DelayValidation processes, starting with what validation is, why it all required, what are different kinds of validation done by runtime engine or pipeline engine and finally explaining all these concepts with examples.

SQL Server Integration Services (SSIS) – Checkpoint Restart-ability January 27, 2009

Checkpoint Restart-ability

Normally ETL operations are very complex in nature and time consuming process as it often deals with millions of records while pulling it or doing transformation on it. Now even if a package fails in middle of its execution; on next execution it will again start from the begining, repeating all the tasks completed in last run.
SSIS provides Checkpoint restart functionality which simplify the recoverability of packages that contain complex operations and can provide significant time saving because the package does not need to reprocess all of the tasks prior to the checkpoint and will start from last point of failure.

Transaction Support
By Default every component in a SSIS package executes in its own transaction. Using Transaction Support feature of SSIS you can group two or more components in a single group and let all those components inside that group to execute in single transaction.
I have written an article covering all aspects of SSIS Transaction Support functionality, starting with how to enable a transaction on a group of components, what are different options available, execution behavior in these available options, examples of Transaction support, its configuration and finally best practices to follow while using this feature.

SSIS Event Handlers
Like any other event driven programming language, SSIS package and its components also generate events in their execution life-cycle. You can extend package functionality by writting event handlers for these events and can make package management easier during runtime.
I have written an article covering all aspects of SSIS Event Handler functionality, starting with what Event Handler is, examples of some events, it usage scenarios, its configuration and finally best practices to follow while using this feature.

SSIS Event Logging
While troubleshooting your SSIS package or tuning your SSIS package for performance you need to know what SSIS Runtime Engine and SSIS Pipeline Engine are doing under the hood. For that purpose, SSIS provides Event Logging feature which traces the execution of SSIS Package and its components during its execution life-cycle. I have written an article covering all aspects of SSIS Event Logging, starting with what Event Logging is, it usage scenarios, its configuration and finally best practices to follow while using this feature.

SQL Server 2008 has come up with different compelling new features. One of them is T-SQL Enhancements which increase the productivity of developers by reducing overall development time and also improves the performance of SQL Server.

I have written an article covering few of the T-SQL Enhancements, for example
· Intellisense Enhancements
· Syntax Enhancements
· Object Dependencies Enhancements
· Using the FORCESEEK Table Hint
· GROUPING SETS

Refer this link for more details.

In the next article, I will be writing about new data-types introduced in SQL Server 2008.

Introduction of SQL Server Integration Services – A Tutorial article January 7, 2009

SQL Server Integration Services (SSIS) is a platform for building high performance data integration and workflow solutions. It allows creating packages or rather SSIS packages which are made up of tasks that can move data from source to destination and if necessary alter it on the way. Not only this, it can be used for several other purposes for example, to automate maintenance of SQL Server databases, update multidimensional cube data etc as well.

In this article of 4 parts, I have discussed about SSIS at introductory level in details.

Part 1 – In this part, discussion is about the SSIS, its origin or brief history, SSIS Package and its components, different ways to create SSIS packages. Refer the link below for more details.
http://www.sql-server-performance.com/articles/biz/SSIS_Introduction_Part1_p1.aspx

Part 2 – In this part, discussion is about the Data Flow Task in SSIS, different components which makes of data flow task, for example Transformation, Data Source Adapters, Data Destination Adapters and Data Paths. Refer the link below for more details.
http://www.sql-server-performance.com/articles/biz/SSIS_Introduction_Part2_p1.aspx

Part 3 – In this part, discussion is about using Import and Export Wizard and SSIS Designer. At last we will go through some examples of creating SSIS packages. Refer the link below for more details.

Part 4 – In this part, discussion is about SSIS API Programming. We will create and execute a simple package programmatically using SSIS API Object Model.
http://www.sql-server-performance.com/articles/biz/SSIS_Introduction_Part4_p1.aspxIn the next article,

I am going to write more about the features and properties of SSIS for example Even Logging, Event Handlers, Transaction Support, Checkpoint Restart-ability and SSIS validation process. So stay tuned to see the power and capabilities of SSIS.
