Database services

The database services provide database support and JDBC connectivity using the application logic layer architecture for services. The database services are:

The database services provide a common and easy-to-use interface to access relational databases through services that use the Java™ standard JDBC interface. It does not provide JDBC drivers, but these are available from database vendors.

All database services use a specific format (HashtableFormat) to build records that the service object places in the database and format the data returned from a query into the process context when there is a single record in the response. Some database services in the toolkit also use another specific format, HashtableIndexedCollectionFormat, to update the process context when the result of a query to the database is a set of records.
