Answer 1

The idea is that you do not open and close a single connection to your database, instead you create a "pool" of open connections and then reuse them. Once a single thread or procedure is done, it puts the connection back into the pool and, so that it is available to other threads. The idea behind it is that typically you don't have more than some 50 parallel connections and that opening a connection is time- and resource- consuming.
