Using DBMS, you can quickly and easily create applications to manipulate and control the data involved in the application. DBMS gives you the underlying structure for maintaining data, organizing it, inquiring and reporting on it, and purging it.

A comprehensive manual contains instructions required to design and implement application systems using the Database Management System.

A DBMS generated application system is always standard. Each program uses the same descriptions, terminator keys, prompts, etc. A change made to any item is changed everywhere that item is used. A change to any program is automatically made to each function and in all application systems.

The simple English prompts and descriptions are easy for the operator to understand, and there is no need to learn new terminology or data processing skills. The professional screen displays identify all information, eliminating the need to constantly reference operator manuals. The keyboard entry process is made simple with the use of help prompts (also called table prompts) and defaults. Further, incorrect entries are changed quickly and easily which helps any operator overcome the initial fear of using a computer.

Supporting an installation that uses a DBMS application system is simplified. No matter what the application, all processes are performed in the same manner, and the error recover and restart procedures are the same for all. More importantly, each of the DBMS program functions allows simplified and straightforward recovery procedures. Most of the program functions may be restarted directly at the point where they left off. The backup procedures provide quick recovery from more serious errors.

The development of a DBMS application system is largely automated. A large part of the system is built at the same time data descriptions and relationships are determined. In fact, since no programming is necessary and development is fast enough, special reports and inquiries may be developed per customer request.

The software maintenance function is virtually eliminated. To change to the operation of any of the programs, copy new versions of the program functions as required. The replacement changes the functions throughout the application system, and for all application systems. Changes made to headings are changed once, which changes all displays and reports that use the heading. Changes made to file structures and organizations automatically generate a file conversion function.

All DBMS program functions operate in multi-terminal installations. Most of the program functions allow simultaneous operation by two or more operators. This is particularly useful for large posting runs and file maintenance. Other program functions prevent other users from performing the same function or accessing the same files or records, as required.

Because similar functions are performed using the same program functions and because redundant data descriptions are all but eliminated, DBMS application systems require far less disk space than their conventional counterparts. The savings are greater for larger systems.

Using DBMS, application systems automatically make use of advanced programming techniques that increase system efficiency. These techniques provide rapid access, fast response, and increased system throughput. Developed by professional programmers, the program functions allow novices and occasional users to achieve professional results. In the case where more efficient techniques are developed, upgrading the application systems is made with a simply copy of a new program function.

The database is protected from unauthorized access with the use of password protection. Password protection is provided in each of the program functions to prevent their usage without prior knowledge of the passwords. Individual selections in menus may also be protected.

As the information needs of businesses evolve over the years, DBMS application systems keep pace with these needs. Changes usually require only slight modifications of the dictionary and/or the control files. Extensive redesigning efforts and cumbersome modification procedures generally are not required.
