Chapter 1 Introduction System Development Life Cycle (SDLC) methodologies are mechanisms to assure that software systems meet established requirements (DOJ‚ 2000). These methodologies impose various degrees of discipline to the software development process with the goal of making the process more efficient and predictable. For the purpose of discussion in this paper‚ SDLC methodologies are divided into two groups (traditional and lightweight). The following introductory sections

Software Development Lifecycle (SDLC) Software (System) Development Life cycle Model Software life cycle models describe phases of the software cycle and the order in which those phases are executed. Each phase produces deliverables required by the next phase in the life cycle. Requirements are translated into design. Code is produced according to the design which is called development phase. After coding and development the testing verifies the deliverable of the implementation

Introduction Software systems development is‚ from a historical perspective‚ a very young profession. The first official programmer is probably Grace Hopper‚ working for the Navy in the mid-1940s. More realistically‚ commercial applications development did not really take off until the early 1960s. These initial efforts are marked by a craftsman-like approach based on what intuitively felt right. Unfortunately‚ too many programmers had poor intuition. By the late 1960s it had become apparent

Information System (IS) is any combination of information technology and people’s activities using that technology to support operations‚ management‚ and decision-making. In a very broad sense‚ the term information system is frequently used to refer to the interaction between people‚ algorithmic processes‚ data and technology. Information systems are distinct from information technology in that an information system is typically seen as having an ICT component. Information systems help to control

components and purposes of Information Technology (IT) and Information Systems (IS) in organizations. Information Systems is a large umbrella referring to systems designed to create‚ store‚ manipulate‚ or disseminate information. Example of an information system is a pencil and a piece of paper. The two objects themselves are just tools‚ but together they create a system for writing (information). The term Information systems has been around a lot longer than the computer‚ or the term information

However‚ despite this advancement in technology‚ Ding-Dong Hardware in Glan‚ Sarangani Province still uses the manual process in their inventory. The Ding-Dong Hardware finds it hard; hence‚ the database of a systematic inventory was conceived. The researcher conducted interviews and surveys in developing a database computerized inventory system. Using the System Development
