Databases aliases

database.alias.app1-database=mysql-database-dev
database.alias.app2-database=oracle-database-prod
database.alias.app3-database=accessDB-test

Databases aliases are used for changing your databases with out changing the rest of the code.

A sample sql statement

request.getEmployees.classname=com.ai.db.DBRequestExecuor2
request.getEmployees.db=app2-database
request.getEmployees.stmt=your-select-statement-goes-here

See how the app2-database alias could be pointing to any of the above databases. Changing this indirection will not impact the select query called "getEmployees". One can use this mechanism especially to move between development, testing, and production with out extensively changing code.

A note of caution or limitation

Currently there is no concept of a default database. This means with every select statement you have to use a database alias. You can not skip and assume a default one.
