Hi, I am writing a windows application that will be saving a lot of data, and I have designed a database for it in access. However when I go to distribute the application, won't having an access database attached as the backend allow users to just open it and view all the data?? I would really like to keep the data in it confidential. What's the best way of doing this?? Should I even just save the data, say as binary, to .dat files instead? If I do this then I take it I'll have to create datasets and tables in memory at the start to load all the data into. Would this be quicker than using a database?

Any help much appreciated...
