database design best pratice help

Hi all,

I have a question about database design best pratice.

In my db I have about one hundred tables like this:

code
description

To avoid to have a so great number of similar tables in the db
I wonder if it is a good idea to unify all these tables in one big table
like this:

id
code
table_ name
description

The advantages are:

1. only one table in the db instead of 100
2. only one controller to manage the table

Could this be a way to enhance db performance?
Is there any negative point that I don't see?

Thanks for any comments.
