5.1Overview

This section explains the types of VSAM OTDs used with the eWay within the Collaboration Editor (Java), including the OTD’s methods.

You can use VSAM OTD methods with:

ƒTables (table OTD)

ƒViews (view OTD)

ƒPrepared statements (prepared statement OTD)

Views are read-only and for informational purposes only. Use the OTD wizard (see Chapter 4) to create the VSAM Database OTDs.

User-defined OTD

You can use the OTD wizard to create an eGate User-defined OTD. See the eGate Integrator User’s Guide for a complete explanation of how to create a User-defined OTD.

5.2Using Tables

A table OTD represents a database table. It consists of fields and methods. Fields correspond to the columns of a table, while methods are the operations that you can apply to the OTD. This setup allows you to perform select, update, insert, and delete SQL operations in a table.
