Studies rely on information researched by the proponents.
Review of Related Literature
In exploration, we find new techniques, new knowledge, even develop new substances, gadgets, equipment, processes or procedures, imagination and skill is employed by the researcher. The commodities, new devices, services, in technology are needs of man for a better fuller life which is the concern of the research. These useful arts are the products of the technological environment and the end-user is society in general. The excerpt was stated by Josefina Estolas in the book Fundamentals of Research (1995). Science and technology are essential for national development and progress. The State shall give priority to research and development, invention, and their utilization, and to science and technology education according to the 1987 Philippine Constitution (Article XIV, Section 10). Since computer power was the critical resource, efficiency of processing became the main goal. Emphasis was placed on automating existing process such as purchasing or paying, often within single department as indicated by Jeffrey A. Hofer on Modern System Analysis and Design (1996). A major purpose of a database system is to provide users with an abstract view of data. That is the system hides certain details of how the data are stored and maintained as stated by Abraham Silberschatz, Database System Concepts (1999). A database is an organized collection of facts and information. An organizations database can contain facts and information on customers, employees, inventory, competitors, sales information and much more. Most Managers and executive believe a database is one of the most valuable and important parts of a computer-based Information System in accordance with Ralph M. Stair’s Fundamentals of Information System (2001). Initially, all processing was performed on mainframe using a batch approach. Time-sharing was an improvement, but the concept of distributed processing with minicomputers was a quantum leap in computer affordability and convenience. Many companies are replacing their mainframes and minicomputers with minicomputers and LAN as indicated in Understanding Local Area Networks by Neil Jenkins (1995). The biggest asset of companies today is their information--represented by people, experience, know-how, innovations and for a market operator to be able to compete, he or she must have a strong information infrastructure, at the heart of which lies the information technology infrastructure. Thus the study of information systems focuses on why and how technology can be put into best use to serve the information flow within an organization as stated in the URL address: http://en.wikipedia.org/wiki/Information_System#Applications_of_information_systems. The introduction of automated systems have had a huge effect on the world we live in over the last 30 years. Many jobs that your grandparents would have done are now done by automated systems as http://www.gordonschools.aberdeenshire.sch.uk/Departments/Computing/StandardGrade/AutoSysWeb/9Implications.htm indicates.

In our society today, computers are the most widely used tool in performing task and jobs. Computers not only provide entertainment but it is also used in different roles which is important to our company. Computers are found in every part of the society like schools, businesses, entertainment, etc. Modern times require computer because of its capabilities, which is necessary for our jobs. Computers have become a necessary in our life because it makes man’s job easier and faster than manual work. Computers’ capabilities in accomplishing tasks for the user make it a valuable tool in our daily life according to Ronald Vilaga and Piere Conde form the study “Enrollment System for GEN3 Computer Education. With today’s technological advancements, automation plays an essential role on business industries....
