SQL server database to UML

Yes, of course, but only if your database already has a schema supporting structures which can be mapped onto UML or if you can evolve or create such schema with your database. When you have it, you can create data structures to support UML with a mapping code. Basically, creating of such a mapping code is the main and fundamental kind of programming chores in using relational databases in software, especially object-oriented.

Now, this is it, because… you did not specify almost nothing relevant to the problem, starting with the main goals of your activity. Please see my comments to your question. So, based on the idea I explained above, you need to create requirements, general sketch of the project, architecture, design components, implementation… just to start and to end.

This would look like a pretty serious project. It is perfectly feasible though, and I would say, success is guaranteed, but… If you still have no clue, well, I would say you need to start with hiring a system architect and/or leading developer. Seriously.
