Overview

The following step is performed in this tool mentor:

Compare and Synchronize

Rational XDE compares a Data Model with an existing DDL script file or database schema. (See helpbook iconData Model Comparison .) The differences can then be synchronized between the model and the DDL or database. (See helpbook iconData Model Synchronization .) You initiate this comparison and synchronization process using the Data Model to Database Synchronization Wizard. (See helpbook iconComparing and Synchronizing the Data Model .)

Rational XDE requires you to compare and synchronize your Data Model from the database level. The DDL or database schema that you are comparing must use the same name as your Data Model database. You must also compare to a DDL or database that uses the same database management system (DBMS) as the Data Model database.

Refer to the Rational XDE online Help topic helpbook iconData Model Compare and Synchronization .

A connection with the database is needed for the compare and synchronization process. The following Rational XDE online Help topics provide information on establishing database connections for a specific DBMS:

  • helpbook iconOracle Database Connections
  • helpbook iconSQL Server Database Connections
  • helpbook iconSybase Database Connections
  • helpbook iconDB2 Database Connections
