I still don't quite understand but hopefully I can select the best solution for you based on a few questions.
1) Should the data be available over the internet?
2) should it be available to everyone or only authorised people?
3) does there need to be an input method for the data or will it be done automatically via an import of some kind?
4) if you need an input method does that need to be available over the internet?
5) should the data be private to the person or private to anyone who can log in?
