SQL Server unlike Access does not have a user front end package that goes along with it. YOu must design and program one yourself for the users to access and manipulate data. People generally use, Access, >net, ASp, VB or someother program to create the user interface.
What is the best way to allow the users to actually enter and update data depends completely onthe circumstances. If you only have one or two poeple who will be entering and updating data from a local office, Access is probably the simplest and fastest interface to use. If the users need web access or need remote out of the office access, the a swebsite built from asp, or J@EE or .net is probably a better choice.
In any event you basically create a form that has the data entry fields and then allows th user to change delete or add data. Each of these actions runs a SQL Stament or stored procedure to perform the action. You will also need to create programs to validate the data based on business rules and to log in users. You will also need to set up security on the databse so users only have th appropriate access, etc.
The for designs themselves are generally based on some combination of what the interface will allow, what the users want and what kind and amount of information they are viewing and updating.
