RDBMS

RDBMS datasources allow you to create a data service using a relational database as the data storage type.

The options in the above window are described below:

datasource type

There are two types of RDBMS datasources as follows:

• Default
  For the default type, connection properties such as driver class, URL and credentials must be entered as shown in the example above.
