Using Open Source Database

Hi,
Part of our road map is to use an open source database besides commercial
databases (oracle and sql server), we need to select an open source database
to build the necessary skills for administration and operation.

Then we would put guidelines on which applications should use open source
database and which to use Oracle.
Then migrate these applications to the new open source database.

Part of this exercise is a financial exercise on the savings resulting from
this transformation (CAPEX & OPEX). So do you have any pointers, case
studies, and so on?
