What is Software process framework And, Umbrella activities

Image
  ❖ Software generic process framework activities .   A process framework establishes the foundation for a complete software process by identifying a small number of framework activities that are applicable to all software projects, regardless of their size or complexity. • In fig each framework activity is populated by a set of software engineering actions. A collection of related tasks that produces a major software engineering work product. • Each action in process framework is populated with individual work tasks that accomplish some part of the work implied by the action. 1. Communication: Communication framework activity involves heavy communication and collaboration with the customer,encompasses requirements gathering, data gathering and other related activities. 2. Planning: Planning activity establishes a plan for software engineering work that follows. Planning describes the technical tasks to be conducted, the resources that will be required, schedule, and the risks...

Software engineering as layered approach

 * Software engineering as layered approach


1. A quality focus: It defines the continuous process improvement principles of software. It provides integrity that means providing security to the software so that data can be accessed by only an authorized person, no outsider can access the data. It also focuses on maintainability and usability.

2. Process: It is the foundation or base layer of software engineering. It is key that binds all the layers together which enables the development of software before the deadline or on time. Process defines a framework that must be established for the effective delivery of software engineering technology. The software process covers all the activities, actions, and tasks required to be carried out for software development.

3. Method: During the process of software development the answers to all "how-to-do" questions are given by method. It has the information of all the tasks which includes communication, requirement analysis, design modelling, program construction, testing, and support.

4. Tools: Software engineering tools provide a self-operating system for processes and methods. Tools are integrated which means information created by one tool can be used by another.

The quality of software is good when the components of the software are developed for certain application and are useful for developing other applications. 

 Before specifying a system requirement, system functionality, before determining the hardware platforms, first determine, whether it adds value to the system.

.All design should be as simple as possible, but no simpler. This facilitates having a more easily understood and easily maintained system. It doesn’t mean that features should be discarded in the name of simplicity.

.Simple also does not mean “quick and dirty.” In fact, it often takes a lot of thought and work over multiple iterations to simplify.

What is Constants, Variables, and Data Types

Image
                                          Constants   Constants in java refer to fixed values do not change during the execution of a program , Java support several types  of constants as illustrated. .Integer  Constants      An integer constant refer to a sequence of digits , There are three types integers .namely decimal imager octal integers and hexadecimals integers . Decimal integers consist of a set of thing preceded by an optional minus sign Valid of decimals integer constant  .Variables  A variable is an identifier that denotes a storage location seed to store a data value unlike constant that remain unchanged during the execution of a program , a variable may take different values at different times during the execution of the program ,we had used several variable for instance , we used variables length and breath to store the values o...
