IMS Database Application Programming

Learn how to write application programs that use Data Language One (DL/I) to process Information Management System (IMS) databases.

\n
• Describe the basic differences between files and IMS databases as they relate to application program coding and logic
\n
• Describe the terms and processing characteristics of IMS hierarchic data structures
\n
• Construct DL/I calls for either COBOL or PL/I language programs
\n
• Write, test and debug a batch application program that uses the DL/I call functions
\n
• Use the IMS Test Program to prototype application program calls, and to perform ad-hoc read and update access to an IMS database
\n
• Describe the applications and uses of other DL/I features
\n
• Program for recovery and restart using DL/I calls to establish synchronization points
\n
• Describe the functions provided by High Availability Large Database (HALDB), and any program differences when accessing a Full Function database or a HALDB
\n

This is an intermediate course for individuals who write programs in Common Business Oriented Language (COBOL), or Programming Language One (PL/I), or Assembler language using DL/I to navigate through an process IMS databases.

You should complete:
