Creating Connections to the Java Dictionary 

Use

You use this procedure to create a connection profile and establish a connection to the Java Dictionary.

The Java Dictionary allows you to define database tables in a database-independent way. The table definitions are organized in dictionary projects. The SAP NetWeaver Developer Studio allows the Java Dictionary to be accessed through the Data Source Explorer.

When you are using the Java Dictionary, you are accessing a metadata representation of a physical database only.

If you plan to use a native database to define your tables, you have to create a connection to that database.
