If you're using EF, you just add, change or delete objects from the collections tied to your database wrapper instance, then call SaveChanges to save all changes you've made.

@Christian Graus can you give me some example that how can i add, change or delete objects from the collections tied to your database wrapper instance

You have a class that has a list of DB objects, you just search for the object you want to remove then call the Delete or Remove ( I forget ) method of that collection. You can actually create a new object that has the right id and pass that in to the delete method. You create a new object, and call add. You can search for an object and change it, then it's changed, you don't need to do any more.

Overall, i suggest buying a book or reading some articles.
