Sketching your job designs

Start your job designs by sketching out the data flow. You can then fill in the details later.

A job design contains:

• Stages to represent the processing steps required
• Links between the stages to represent the flow of data

There are three different types of job in InfoSphere® DataStage®, depending on what edition or editions you have installed:

• Parallel jobs. These run on InfoSphere DataStage servers that are SMP, MPP, or cluster systems.
• Server jobs. They run on the InfoSphere DataStage Server, connecting to other data sources as necessary.

There are two other entities that are similar to jobs in the way they appear in the Designer, and are handled by it. These are:

• Shared containers. These are reusable job elements. They typically comprise a number of stages and links. Copies of shared containers can be used in any number of server jobs and parallel jobs and edited as required. Shared containers are described in Shared containers.
• Job Sequences. A job sequence allows you to specify a sequence of InfoSphere DataStage server or parallel jobs to be executed, and actions to take depending on results. Job sequences are described in Building sequence jobs.
