Hi i am to design an online database system for a hospital . The requirement is that i have three types of user to login in the system online one is DOCTOR and PATIENT and CLERK. My question is how to design the table for this requirement . Either a single table will be useful in this case with the user types field or separate table is to be built for each type of user. Also note that the user have privileges according to there type and each user has its own main page or user interface.
Need Some Suggestion from Database Expert !
