Application Engine Overview

Application Engine is a PeopleTools designed to help you develop background SQL processing programs. This tool is intended to be used by developers with knowledge of SQL, SQL tools, and PeopleTools.

Application Engine offers an alternative to writing COBOL or SQR programs for background SQL processing. While Application Engine does not generate, parse, or understand SQL, it does execute SQL that you provide.

Note: DB2 UDB for OS/390 and z/OS is the official IBM name for the database management system (DBMS). In the current PeopleTools release, Oracle no longer supports the OS/390 operating system, only z/OS, its replacement. For the sake of brevity, you may find references to DB2 UDB for OS/390 and z/OS asDB2 z/OS, and it sometimes refers to DB2 UDB for Linux, UNIX, and Windows asDB2 UNIX/NT.
