I am making a project where I have to create many companies and many Employees in it and I have to make a attendance register also.
my question is can I use multipal tables in one database attached to my project(Like a separate table for log in ,Employers or companies,employees ) or one table is enough. where I have to make a log in form also where users log in and then they can create Employers data and after that employees in that I will have to fetch the data also for the prints.

and can I connect all my tables to all my forms?
I am working with VS2010 Express
