The Data Integration Service can connect to multiple relational databases. The databases that the service can connect to depend on the license key generated for your organization. When you create the Data Integration Service, you provide connection information to the databases.
Create the following databases before you create the Data Integration Service:
Data object cache database
Stores cached logical data objects and virtual tables. Data object caching enables the Data Integration Service to access pre-built logical data objects and virtual tables. You need a data object cache database to increase performance for mappings, SQL data service queries, and web service requests.
Stores profiling information, such as profile results and scorecard results. You need a profiling warehouse to perform profiling and data discovery.
Stores all run-time metadata for workflows, including Human task metadata.
The Data Integration Service uses native database drivers to connect to the data object cache database, the profiling warehouse, and source and target databases. To establish native connectivity between the service and a database, install the database client software for the database that you want to access. For more information, see
Configure Native Connectivity on Service Machines.
