Database abstraction means using a common db function for
querying. This would be great when you are switching from
one database to another. You won't have to change each and
every database function. Instead of that you can simply
change the database function names in one file. This should
be considerable, if in future you are planning to change the
database. The disadvantage of this is, it will slower down
the performance.
