Computer software can be divided into two main categories: application software and system software. Application Software: Application Software includes programs that do real work for user. Example: Payroll systems‚ Inventory Control‚ Manage student database‚ Word Processor‚ Spreadsheet and Database Management System etc. Application software consists of the programs for performing tasks particular to the machine’s utilization. Examples of application software include spreadsheets‚ database systems

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

What Is Computer Software? When you think of a computer imagine a machine made of two parts. The first part is the computer hardware‚ the physical parts of the computer that you can actually touch. Some examples of hardware are disks‚ monitors‚ boards‚ chips‚ etc. Hardware does all of the physical work of the computer‚ from memory storage to display. The second part‚ what we call “computer software”‚ acts as the brain of the computer‚ telling the hardware what to do and when and how to do it

Systems Development Life Cycle • Project planning: Establishes a high-level view of the intended project and determines its goals. The importance of the planning stage is to determine what technologies exist or can be developed to solve the problem that has been identified. An economic feasibility analysis is used to determine if an organization can afford the system and if the system will provide a return on the investment. An operational feasibility analysis examines the human element of the

There is no going back once a phase is completed. Iteration across Life Cycle Models Iteration means that the work tasks are done once‚ then again‚ and

Introduction System development methodologies are promoted as a means of improving the management and control of the software development process‚ structuring and simplifying the process‚ and standardizing the development process and product by specifying activities to be done and techniques to be used. It is often tacitly assumed that the use of a system development methodology will improve system development productivity and quality. However‚ there is little empirical evidence to support this

Systems Development life Cycle (SDLC) ➢ The traditional methodology used to develop‚ maintain‚ and replace information systems. ➢ The evolution of process that is followed in implementing a computer-based information system subsystem. ➢ Also known as Systems life cycles‚ Systems Development Methodology‚ Project Life Cycle‚ and Methodology. Participants: ➢ Their participation depends on the strategic value of the project.

Systems Development Life Cycle The term systems development life cycle (SDLC) is used to indicate traditional development methods which are used by organizations on large-scale IT projects. There is a structural framework in SDLC comprised of processes that are executed in sequence during the development of information systems. Step one involves a feasibility study for the product. During this step‚ the software analyst’s job is to work with strategy makers to establish
