Difference bw database and datawarehouse

It is correct. The data warehouse is for reporting that storing data from CLM server (by ETL) and historical data, it is required for DW reports.
The JTS and it's applications (e.g. RTC/RRC/RQM) have a database for their resources/artifacts. These resources/artifacts are Extracted/Transformed/Loaded (ETL) to the data warehouse for reporting (e.g. BIRT/IBM Rational Reporting for Development Intelligence (RRDI)/IBM Rational Insight).
