Functional decomposition is a method used to design a detailed structure of components or modules of the software. Functional decomposition specifies the functions, activities, processes or actions that the component or module of the software has to perform. You can better understand the concept of functional decomposition with the help of an example. So in this context, we … [Read more...] about Functional Decomposition

Modularity in Software Engineering
Modularity specifies the separation of concerned 'components' of the software which can be addressed and named separately. These separated components are referred to as ‘modules’. These modules can be integrated to satisfy the requirement of other software. In this context, we will be discussing the concept of modularity in software design, why do we require modularity, … [Read more...] about Modularity in Software Engineering
Feasibility Study
A feasibility study specifies whether the proposed software project is practically possible or not. Whenever there arises a need for any software you don’t directly jump in developing the particular software. Instead, we must first analyze certain facts to realize whether the software is worthwhile or not and this is called the feasibility study. The feasibility study … [Read more...] about Feasibility Study
Requirement Engineering
Requirement engineering is the process of collecting, validating and managing the requirements essential for the development of the software, specified by the clients or the end-users. This task is performed at the initial stages of software development. The requirement engineering process involves a team of software developers or engineers, business analysts, customers and … [Read more...] about Requirement Engineering
Difference Between Black Box Testing and White Box Testing
Black box testing and white box testing both are the methods of testing the software. But, the main difference between black box and white box is that the black box testing checks the functionality of the software (external view) whereas, the white box testing, tests the internal structure or procedural design (internal view) of the software. Black box testing and white box … [Read more...] about Difference Between Black Box Testing and White Box Testing
