[Batman] I recently started as a patrol officer in Gotham. How much will Batman know about me?

In different iterations of Batman, he's seen as knowing the names of officers making up whole departments.  How much does he actually know about each one?

He has supercomputers and an extraordinarily advanced research capability at his disposal. He doesn't know anything about you initially. He has an excellent memory, but Gotham is a big city with a big police force, and your one guy. When your normal duties cause you to become involved with a major super villain he does a check on you, and gets all sorts of information. Likely he only knows your name and anything relevant from that point, though he likely doesn't forget it once he does know, and he can access an absolutely enormous amount of information on you and anyone you are connected to.
