Doctrine_Connection is a wrapper for database connection. It handles several things:
<ul>
<li \> Handles database portability things missing from PDO (eg. LIMIT / OFFSET emulation)
<li \> Keeps track of Doctrine_Table objects
<li \> Keeps track of records
<li \> Keeps track of records that need to be updated / inserted / deleted
<li \> Handles transactions and transaction nesting
<li \> Handles the actual querying of the database in the case of INSERT / UPDATE / DELETE operations
<li \> Can query the database using the DQL API (see Doctrine_Query)
<li \> Optionally validates transactions using Doctrine_Validator and gives
full information of possible errors.
</ul>
