Connection pool is an mechanism of pre-creating group of connections and keeping them in cache memory for use and reuse.
DataSource is an interface in javax.sql ackage.Datasource is nothing but object oriented representation of connection pool or DataSource can be called as connection factory.
Coming to DataSource implementations some third parties have implemented this datasource and also server vendors like Tomcat,Websphere also implemented.
NOTE:mostly we use the server implemented DataSources
