Software Engineering Practice

People who create computer software practice the art or craft or discipline that is software engineering. But what is software engineering “practice”? in a generic sense, practice is a collection of concepts, principles, methods, and tools that a software engineer calls upon on a daily basis. Practice allows managers to manage software projects and software engineers to build computer programs. Practice populates a software process model with the necessary technical and management how-to’s to get the job done. Practice transforms a haphazard unfocused approach into something that is more organized, more effective, and more likely to achieve success.

Core principles
The dictionary defines the word principle as “an important underlying law or assumption required in a system of thought” throughout this book we discuss principles at many different levels of abstraction. Some focus on software engineering as a whole, others consider a specific generic framework activity (e.g., customer communication), and still others focus on software engineering actions (e.g., architectural design) or technical tasks (e.g., write a usage scenario). Regardless of their level of focus, principles help us establish a mind set for solid software engineering practice. They are important for that reason.

First principle: the reason it all exists

A software system exists for one reason: to provide value to its users. All decisions should be made with this in mind. Before specifying a system requirement, before nothing a piece of system functionality, before determining the hardware platforms or development processes, ask yourself questions such as: does this add real value to the system? If the answer is no, don’t do it. All other principles support this one.

Job Descriptions and Qualification of a Computer Software Engineer

Here are the primary responsibilities of a Computer Software Engineers:

* They participate in designing and developing many types of software.

* They can be involved in the creation of computer games, word processing and business applications.

* They create operating systems and network communications.

* They also develop programs that can communicate with the operating system to make the computer work.

* They must have a Bachelor’s degree in many fields of computer systems and technologies.

One of the fastest growing jobs this decade is the Computer Software Engineer. A Computer Software Engineer needs to be updated with the latest technology and strive to get new skills every day. The work requires creativity as the program needs to work properly for the system. Most of them work for big corporations that created new program for the market. They are involved in designing and developing many types of software. Most of the software they are creating today has something to do with computer gaming. They also develop business applications which contain programs that help major corporations with the business operation.

The Computer Software Engineer needs to analyze the needs of the business before beginning to create a software program. He needs to make sure that the program he is going to make is according to the client’s needs, and then he will test it and make sure that it will help the client run the business. During this period he will also create detailed sets of instructions, also known as algorithms that will tell the computer what to do. These instructions will be converted into a computer language which is called programming or coding. Doing all these tasks, he needs to arm himself with the knowledge in different programming languages. The programming languages that are most commonly used include C, C++, and Java.

All About Software Engineering And Development

Software engineering, known as SE, is the development, design, maintenance and documentation of software by applying practices and various technologies from fields such as computer science, engineering, application domains, project management, digital asset management and interface design.

The conception, development and verification of a software system is what software engineering is all about. It is necessary to identify, define, realize and verify the resultant software’s required characteristics. Necessary testing is required for attributes such as reliability, functionality, testability, maintainability, ease of use, availability and portability. In software engineering, software can be verified to meet these requirements by having design and technical specifications prepared and implemented correctly. The characteristics of the software development process are also important in software engineering. Development itself, development duration and risks in software development are examples of such characteristics.

A computer uses software as part of its system that allows the hardware to operate properly. Software can be system software or application software. System software includes the main operating system and a variety of other utilities that enable the computer and its applications to run. Application software includes the computer programs and relevant documentation responsible for end-user data processing tasks. This kind of software is developed for such tasks as word processing, payroll, inventory and production control.

Software Development

A series of processes undertaken systematically to improve a business through using computerized information systems is what is known as software development. There are two major components to software development, which are systems analysis and design.

Systems analysis is the specification of what exactly the system is required to do, or the main objective. Design is about how to make the system do what is required of it. For system analysis, it is required to study the current system by certain procedures in order to gather and interpret data and facts, identify any problems and use this data to improve the system currently in use. System design refers to the process of developing a new system, concentrating heavily on the technical specifications and other specifications that make the system operations.

Software Development Life Cycle

Software Development Life Cycle, or SDLC, is a sequence of events done by designers, analysts and users to develop and execute an information system. There are a number of stages to this practice, which can overlap. The stages are Preliminary investigation (which is feasibility study), Determination of system requirements (which is analysis), Design of system, Development of software, System testing, System Implementation and System Maintenance in that order.
