Create a Database class

[DelaMarc]

I recommend creating a Database class (that would also be a singleton). It would be used to handle all database manipulations and have methods that would encapsulate the Select, Update and Delete operations of a database and return the desired result.
This class would also catch the exceptions relative to database malfunction.
With such a class, the database connexions would be handled more smoothly and if would avoid to manually put a try/catch at every SQL request in the server code.
