Introduction
(Next) (Previous) (Table-of-Contents)

This suite of sample programs will show how to create, manipulate and delete a table within a relational data base. An item file resides on an IBM Mainframe as a VSAM, Keyed-Sequential-Data-Set (KSDS) using EBCDIC encoding. This suite of sample programs will show how to migrate the data in the KSDS to a relational data base. A suite of COBOL programs with embedded SQL will be used to demonstrate each of the steps in the process.

Summary
(Next) (Previous) (Table-of-Contents)

The purpose of this suite of programs is to provide an example of how to read an item file that is a VSAM, Keyed-Sequential-Data-Set (KSDS) and create a table within a relational data base model using embedded SQL in the COBOL programs. The examples show how to create, manipulate and delete a table within a relational data base.
