I do not think anyone is answering you as the answer depends on how you
are using the database and what your expectations are?
If your application is using the database all the time it is worth making
use of a connection pool, to recycle connections, rather than connect to
the database directly.
If your application is in a shared environment like JavaEE you may wish to
look up a JNDI data source and share the database connections with the rest
of the application?
If your code only talks to the database for a bit, and then is quiet it may
be kind to do as you say and create the dataStore, use the connections for
a bit, and then dispose of everything until next time.
