What is the difference?

I’ll be taking database course soon, so I want to know about the differences between oracle, mysql, postgres, ms sql ?
And which is better ?

There’s a good comparison here:

Comparison of relational database management systems - Wikipedia, the free encyclopedia

Each has their advantages and disadvantages, it depends how you will be using them and on what platform as to which is best.

really good one here: Comparison of different SQL implementations

as for which one is better, i think it’s MS Access 97

damn fine database, that

:cool:

Thanks for the nice links.

I will suggest to you that you do the oracle course now time using the oracle because when we will use security opportunities then else oracle will move the market.
