API = Application Programming Interface

All that means is a library of functions that programmers can use to achieve some result.

For example IBM provides an API that you can use to access DB2 programmatically. This is the DB2 API. Someone once authored a DataStage stage that invokes functions in the DB2 API. This stage is called the DB2 API.

There is also an API for working programmatically with DataStage. This is called the DataStage API. The dsjob command is an example of a program that uses functions in the DataStage API.

Well, Java API package for DataStage consists of Stage class, Column class, and Row class. Various methods in these classes for you to manipulating rows and querying meta data. However, these classes can be used only when using the Java client stage and the Java Transformer stage.
