Data Warehouse

The primary concept of data warehousing is that the data stored for business analysis can most effectively be accessed by separating it from the data in the operational systems. As per Ralph Kimble “A data warehouse is a subject-oriented, integrated, time variant and non-volatile collection of data in support of management’s decision making process.”

 

IBM InfoSphere DataStage

InfoSphere DataStage is a powerful data integration tool. It was acquired by IBM in 2005 and has become a part of IBM Information Server Platform. It uses a client/server design where jobs are created and administered via a Windows client against central repository on a server. The IBM InfoSphere DataStage is capable of integrating data on demand across multiple and high volumes of data sources and target applications using a high performance parallel framework. InfoSphere DataStage also facilitates extended metadata management and enterprise connectivity.

It has three levels of Parallelism which are:

1. Pipeline Parallelism

2. Data Parallelism

3. Component Parallelism

It also has different methods to implement partitioning so that the total processing time for the job execution can be reduced. The degree of partitioning is decided by configuration file. There are 9 partitioning methods that can be used depending on scenario and stage used.

Datastage has two different versions namely Server & Parallel. Server version is used to execute jobs in sequential mode whereas parallel version is used to execute jobs in parallel using the concepts of partitioning and pipelining. Due to increase number of data, the server versions is becoming outdated & most of the projects use only Parallel version to implement business requirement.

Steps involved in Datastage Job design :-

1. Understand the requirement & split in small junks like flow chart.

2. Open Parallel Job in the designer in designing canvas & use the different stages to implement the requirement (as per the flow chart).

3. Compile and execute the job.

4. Verify the log & test the converted data.

There may be other small steps used like usage of parameters/sequencers etc in order
