hopefully as a means for teaching future people what to do and what not to do. So, when you click your mouse on a resource on the Internet and think that it is so
wonderful, keep in mind that it is even more wonderful than you can imagine, but that there are also even better ways to find reliable information than just following
any link that anyone happens to stick on the Internet.
Yes, you can find myriad sources of information online for free, but many of the materials that you can really count on are not freely available, so you need
to rely on organization and cataloging and indexing to take advantage of those heavy duty sources. And you can rely on libraries to continue to provide you
with materials that you may never be able to access freely on the Internet. Information and organizing information is what libraries are about.
2.3 Basic Concept of Application
Application sometimes called a program that is a series of instructions that the hardware executes one after another
[6]
. In information technology, an application is the use of a technology, system, or product.
The term application is a shorter form of application program. An application program is a program designed to perform a specific function directly
for the user or, in some cases, for another application program. Examples of applications include word processors, database programs, Web browsers,
development tools, drawing, paint, image editing programs, and communication
programs. Applications use the services of the computers operating system and other supporting applications.
2.4 Basic Concept of System Analysis
Analysis is the process of breaking a complex topic into smaller parts from among various alternatives to achieve a better understanding of it. In system
development process, there is system analysis that provides the project team with a more thorough understanding of the problems and needs that triggered the
project. The system analysis requires working with system users to clearly define business requirements and expectations for any new system that is to be purchased
or developed
[3]
2.5 Basic Concept of System Design
Information system design is defined as those tasks that focus on the specification of a detailed computer-based solution. It is also called physical
design. Thus, whereas systems analysis emphasized the business problem, system design focuses on the technical or implementation concerns of the system.
System design is driven by the technical concerns of system designers. Hence, it address the IS building blocks from the system designer’s perspective.
The system analyst serve as facilitators of system designs
