DataSource==database-conn-source

DataSource=database conn source, a source of Connection objects (or conn poolsss)

Increase your retention rate by putting aside all the noise beside the top 2 [two] things about a data source:

1) each data source has a name in a jndi tree
2) a data source is a conduit to a conn pool. Think of it as a pipe to get the stuff (h2o or physical connections) from the pool

[[ oreilly weblogic ]] has a short and sharp coverage of datasource ^ conn pool in a weblogic cluster

a data source and a connectionFactory are both registered on jndi tree

Q: a data source is similar to a connectionFactory in jms and other areas. Any real difference?
