An agile process reduces the agility and cost of change because software is released in increments and change can be better controlled within an increment. Agility argue that a well designed agile process “flattens” the cost of change curve shown in following figure, allowing a software team to accommodate changes late in a software project

Unified process (UP) is an architecture centric, use case driven, iterative and incremental development process. UP is also referred to as the unified software development process. The Unified Process is an attempt to draw on the best features and characteristics of traditional software process models, but characterize them in a way that implements many of

Component Based Development The component based development model incorporates many of the characteristics of the spiral model. It is evolutionary in nature, Specialized process model demanding an iterative approach to the creation of software. However, the component based development model constructs applications from prepackaged software components. Modeling and construction activities begin with the identification of

Prescriptive process model were originally proposed to bring order to the chaos of software development. Prescriptive process model define a prescribed set of process elements and a predictable process work flow. “prescriptive” because they prescribe a set of process elements framework activities, software engineering actions, tasks, work products, quality assurance, and change control mechanisms for

In order to build software engineering a layered technology that is ready to meet the challenges of the twenty first century, you must recognize a few simple realities. Problem should be understood before software solution is developed Design is a pivotal Software Engineering activity Software should exhibit high quality Software should be maintainable These simple

In the early days of the World Wide Web, websites consisted of little more than a set of linked hypertext files that presented information using text and limited graphics. As time passed, the augmentation of HTML by development tools (XML, Java) enabled Web engineers to provide computing capability along with informational content. Web based systems

Software takes Dual role of Software and Software Engineering. It is a Product and at the same time a Vehicle for delivering a product. Software delivers the most important product of our time is called information. Defining Software Software is defined as :- 1. Instructions : Programs that when executed provide desired function, features, and

A const member function guarantees that it will never modify any of its class’s member data. The CONSTFU program shows how this works. //constfu.cpp //demonstrates const member functions / class aClass { private: int alpha; public: void nonFunc() //non-const member function { alpha = 99; } //OK void conFunc() const //const member function { alpha
