Codes for Converting MS Access Database to Executable or any other form which will work with VB program even if their is no MS Access Software

I am a student and I am Planning for Project in VB as my collage project. I wanted to know which is the most secured to keep your data secrated as well as secured from others. I have back end in MS Access but i dont want to keep my database wit .mdb extention as any one can open it and can play with my data. So I was wondering whether can we have database in some other format which will work with VB Programs. Say like EXE or Dll or any other format. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
