Custom: This allows knowledgeable Orchestrate users to specify
an Orchestrate operator as a DataStage stage. This is then available
to use in DataStage Parallel jobs.

Build: This allows you to design and build your own bespoke
operator as a stage to be included in DataStage Parallel Jobs.

Wrapped: This allows you to specify a UNIX command to be
executed by a DataStage stage. You define a wrapper file that in
turn defines arguments for the UNIX command and inputs and
outputs.

Note: The above answer is for Parallel jobs

Datastage allows you to create your own stages with custom properties.

There are three types of custom stages:

Custom:
This is Orchestrate based custom stage. Orchestrate operators are used for defining the functionality of the job.

Build:
This is C++ based custom stage. Functionality has to be specified in C++ code. This is then assembled with Build type stage.

Wrapped:
This is UNIX based custom stage. We can define the functionality by specifying the UNIX commands. These UNIX commands become the code of the stage.
