A TMB Web Designs does not involve the problem of data redundancy or inconsistency. Its design is such that it provides the security mechanism to prevent unwanted users from accessing certain parts or whole of the database. For example, tellers in a bank see only that part of database that has information on customer accounts. They cannot access information about salaries of employees. It has many advantages over the file processing system, which stores the permanent records in various files. In this system the problem of redundancy prevails, as files and application programs are created by different programmers over a long period of time.
