Don't build your own DBMS, use SQL Server! You will save a ton of time setting up and learning SQL than trying to create your own protocols, which are a pain in themselves. SQL server is not extremely difficult, plus you get all the benefits of a true RDBMS like backups, stored procedures, security, etc. Processing is done at the server. You will be more valuable because of your new knowledge of SQL server. I don't recommend Oracle, it is more difficult to learn and manage (ever wonder why Oracle DBA's make so much?)

The moral of this story: Use SQL Server.
