Chapter 15. Application Programming for the IMS Database Manager

Application programs can interact with IMS DB in two ways:

• Traditional applications can use the DL/I database call interface.

• Java applications can use the IMS Java function's implementation of JDBC or the IMS Java hierarchical interface, which is a set of Java classes that you can use in Java that are similar to DL/I calls.

This chapter discusses the DL/I database call interface. See Chapter 18, "Application Programming in Java," on page 311 for information about how Java applications call IMS.
