CHAPTER 4

Chapter 4

THEORETICAL FRAMEWORK

Capiz Electric Cooperative is still using their manual system. Payroll system is a computerized payroll system that is designed to give a better service. This is to make sure that their works accurate and it is to less time and effort of the personnel. Computerized payroll system would be a great help to maximize the use of computer and give services to any companies as well as to the capiz electric cooperative.

1. System Security

It is important to any kind of system for an information system, which is design for multi-user environment wherein lot of people can access data. System security can be improved through good security mechanics and can undermine through faulty design or implementation. This theory helped the proponents in developing a system that is secure from the interaction of unauthorized user.

2. Reliability

In computer software, reliability is generally measured how often the product breakdown or requires major services. Reliability can be defined as the probability that an item will continue to perform its intended function without failure for a specified period of time under stated condition. This theory gives the proponents the idea how to implement an effective system by making sure of its reliability.

3. Integrity

Is an attribute that measures the system ability to withstand with the attack its security. It is achieved by preventing accidental or deliberate but unauthorized insertion, modification or destruction of data in the database.

4. Correctness

It is one of the important capabilities of the software to the user is its correctness. Correctness is a great help for the accomplishment of the study by making sure that the software performs its required function. The proponents would expect that correctness of all aspects of such software, including the user interface would be strenuously pursued.

5. Database Design

The process of producing a detailed data model of a database. This logical data model contains all the needed logical and physical design choices and physical storage parameters needed to generate a design in a Data Definition Language, which can then be used to create a database.
A fully attributed data model contains detailed attributes for each entity. Database theory encapsulates a broad range of topics related to the study and research of the theoretical realm of database and database management system.

6. System Design

Is process or art of defining the architecture, components, modules, interface and data for a system to satisfy specified requirement. One could see it as the application of system theory to product development. It is the application of systems theory to product development. There is some overlap with the disciplines of systems analysis, systems architecture and systems engineering. It helps the proponents to satisfy the requirements specified by the user in order to implement the system correctly.
