Do you have some information on Sims 3?

There is a whole ton of information on The Sims 3 website, www.thesims3.com

This is the official website which will tell you all about the game and it's expansions; it also contains a community forum where there is a lot of information.

Essentially, it is a game where you act as the controller of your sims' lives. You can live their life, ie. get a job, buy/build a house, get married, have children.

Pretty much anything you want (within reason) can happen. But I sense you would want more information than that, so I suggest you try the link.
