A software development process, also known as a software development life cycle (SDLC) can be explained as a structure, imposed on the development of a software product. The software development life cycle (SDLC) is an umbrella term for the overall process of developing, implementing, and retiring information systems through a multiple step process from initiation, training, documentation , design, analysis, maintenance, and consulting. Software development life cycle (SDLC)
This unit covers various software process concepts and models. Software process models are described, analysed and evaluated; outlining where they might be appropriately used. During software development, there is a need to have a thorough understanding of the fundamental process activities. Also, there is a need to have a thorough understanding why software processes should be arranged in a way that they can adapt or cope with changes during software development. At the end, students must analyse
know that Software is a collection of executable programming code, associated libraries and documentations. Engineering on the other hand, is all about developing products, using well-defined, scientific principles and methods. Software engineering is concerned with all aspects of software production from its early stages of system specification through the maintenance of the system after delivering it. Software engineering as an engineering branch associated with the development of software product
Discuss how computer-Aided software engineering (CASE) is used to aid companies to be more productive. What is CASE? Computer Aided Software Engineering (CASE) was ‘born’ in mid 1970s with the basic purpose to speed up the software structure process. Core purpose of every business and company is profit, by using every method. Businessmen have keen eyes on market, supply chains, demands and methods of production. ‘Targets’ and there completion is very important in every business. Fast tracks to
Developing computer software and information systems is a procedure that has been usually worked on by various methodologies of development. Software development methodology is defined as the structure of planning, managing and controlling the process of building up an information system. Officially, the methodology of software development is called Software Development Life Cycle (SDLC), which is used mainly in various engineering and industrial work areas like software engineering, applied engineering
Q1. Explain different kinds of software programs. A1. Software may be applied in any situation for which a pre-specified set of procedural steps has been defined. Knowledge content and determinacy are important factors for knowing the nature of a software application. Knowledge determinacy refers to the predictability of the order and timing of knowledge. An engineering analysis program accepts knowledge that has a predefined order, executes the analysis algorithm without interruption and produces
and if the requirement might change it cannot be used . this is used only when the user know completely what they want. Water fall model makes use of the time control effect where a deadline can be set so the target has to reached. Once a phases is completed and a problem is found the whole cycle has to be restarted. The waterfall has other extensions like the v-model Table 2 Advantages and disadvantages of waterfall methodology Advantages Disadvantages Simple and easy to
The functional models originated in the 1950’s. This was done after the first half of the 20th century focused on other types of management diagrams that was already developed. The first of these was known as the Gantt Chart that was originally developed in 1896 by Karol Adamiecki. This model have never been very popular in the West until Henry Gantt designed his chart in 1915. An Information System is a system that is composed of people, computers and the processes that interprets the information
specification can be created which serves the purpose of guideline for the next phase of the model or
Waterfall Process Model Waterfall Process Model or The Classical Life Cycle o was the oldest process model to present a linear framework, describing main phases that are compulsory for a successful software development model. It formed the basis for most software development standards and contains the following stages: Requirements elicitation, Designing, Implementation and Testing. In this model, to begin next stage current stage must be completed. To apply waterfall process model, requirements should
