Software Testing Introduction -: After creating the software the next phase comes for using the software. So it is necessary to test the software that is working well or not. Software testing is a process to evaluate the functionality of a software application with an intent to find whether the developed software met the specified… Read More »
Introduction of data flow diagram -: Data flow diagram is a graphical representation of flow of data in an information system. It is capable of depicting incoming data flow outgoing data flow and stored data. The DFD does not mention anything about how data flows through the system. Flowchart v/s Data flow diagrams-: The difference… Read More »
Introduction of software -: This design is a process to transform user requirement into some suitable form which helps the programmer in software coding and implementation. For assessing user requirement an SRS (software requirement specification) document is created where for coding and implementation there is a need of more specific and detailed requirement in software… Read More »
Introduction of software requirement -: The software requirement are description of features and functionalities of the target system.Requirement convey the expectation of users from the software product. The Requirement can be obvious or hidden known or unknown expected or unexpected from client point of view. Software requirement engineering -: The process to gather the software… Read More »
Introduction –: A project is well defined task which is a collection of several operations done in order to achieve a goal. Like software development and delivery. A project has many character as like.. Every project may have a unique and distinct goal Project is not a routine activity or day to day operation. project… Read More »
V shaped model -: The major drawback of Waterfall model is we move to the next stage only when the previous one is finished and there was no chance to go back if something is found wrong in the previous stage. This problem solution provide the V shaped model. This model provide testing of software… Read More »
Spiral Model Introduction -: This model is describe Software Development process. This model is a combination of both model first is the iterative model and one SDLC model and combined it with cyclic process. This model considers risk which often goes un-noticed by most other model . The model start with determining objectives and constraint… Read More »
Introduction -: In the early stage the waterfall model was very famous for completing the software development process. After some time developer face various problem for developing a software. The main problem was included handling change requests from client during software development. Another problem is the high cost and time required to incorporate these changes.… Read More »
Introduction of waterfall model -: This model was describe about the SDLC process. This is the oldest software development model. Waterfall model is very easy to understand. In the waterfall model has many phase. In this model all the phase are step by step completed. Means if the first stage completed then the next steps comes. It… Read More »
Introduction of models in software engineering -: A model in software engineering come’s in many shapes, sizes and styles.This is very important to understand that a model is not the real world but It is a human construct that help us to understand real world systems. All models has an information input, an information processor… Read More »
