manual/docs/Basic Components - Connection - Introduction.php

+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>
