DL/I databases

You get a logical view of the database in terms of a hierarchy of segments. DL/I lets you manipulate these segments without needing to know how they are organized. DL/I databases are processed by the IBM® licensed program Information Management System/Enterprise Systems Architecture (IMS/ESA®).

CICS® has two programming interfaces to DL/I. We recommend that you use the higher-level EXEC DLI interface. It is straightforward, works with EDF, and can fully exploit a 31-bit environment. The lower-level DL/I programming interface is the DL/I CALL interface.
