You associate a reference data warehouse with a single Model repository. You can select a common reference data warehouse on multiple Content Management Services if the Content Management Services identify a common Model repository. The reference data warehouse must support mixed-case column names.
The reference data warehouse supports the following database types:
IBM DB2 UDB
Microsoft SQL Server
Microsoft Azure SQL Database
PostgreSQL, using a JDBC driver
Allow 200 MB of disk space for the database.
Ensure that you install the database client on the machine on which you want to run the Content Management Service.
