Software engineering

  1. 1. Is the application of a systematic, disciplined, quantifiable approach to the design, development, operation, and maintenance of software, and the study of these approaches. Software Engineering is the branch ofengineering that applies the principlesof computer science and mathematicsto achieving cost-effective solutions to the problems of software development.
  2. 2. Economically Socio- • Around the world, the software economic contributes to economic growth.implications Socially • Software engineering, change the culture of the world, due to the widespread use of computers. E- mail, the Web and instant messaging, allowing people to interact in new ways. The software lowers the cost and improves the quality of health services, government agencies and other social services. Software engineering process
  3. 3. Requirements Analysis Specification Software Architectureengineering process Programming/ Development Test (Software lifecycle) Documentation Maintenance
  4. 4. Requirements Analysis Extract the requirements of a software product is the first stage to create it. It requires skills and experience in software engineering. The result of the analysis of customer requirements is reflected in the ERS document, System Requirements Specification, the structure can be defined by various standards, such as CMMI. It also defines a diagram Entity / Relationship, which embodies the main entities involved in software development. The capture, analysis and requirements specification, is a crucial part, of this stage depends largely on achieving the ultimate goals.Menu Next
  5. 5. The requirements specification describes the expected behavior in the software once developed. Much of the success of a software project will lie in identifying business needs and the functional user interaction for the collection, classification, identification, prioritization and specification of software requirements. Specification Among the techniques used for the specification of requirements include: Use Case. User Stories.Menu Next
  6. 6. The integration of The software infrastructure, application architecture is the development, and design of an application database management component, usually tools, capacity and using architecture leadership required to be patterns. An conceptualized and architectural design projected future, solving generally describes how the problems of today to build a software application. This is documented using diagrams, for example: Class diagrams, Diagrams database, Architecture Deployment diagram, Sequence DiagramMenu Next
  7. 7. Programming Reducing a design to code may be the most obvious part of the software engineering job, but not necessarily the most demanding work and even the most complicated. The complexity and length of this stage is closely related to programming languages ​used, and pre- made design.Menu Next
  8. 8. • Involves checking that the software performed correctly the tasks outlined in the specification of the problem. A testing technique is tested separately each software module, and then test it comprehensively in order to reach the goal. TestMenu Next
  9. 9. Documentation • All documentation regarding the actual development of software and project management, through modeling (UML) use case diagrams, testing, user manuals, technical manuals, etc., all for the purpose of corrections, usability, future maintenance and upgrades to the system.Menu Next
  10. 10. Phase dedicated to maintaining and improving the software to correct errors discovered and incorporate new requirements. This may take longer than even the initial software development. About 2/3 of the cycle time of a project4 life is devoted to maintenance. A small part of this job is to remove errors (bugs), being that most lies in extending the system to incorporate new features and addressing its evolution. Maintenance Models and software development philosophiesMenu Next
  11. 11. Software engineering has several models, development paradigms andphilosophies, which is based on the construction of the software: Waterfall model or Classic (traditional RUP model) (Rational Prototype Unified Model Process) Unified Process Models and Spiral Model software development philosophies Concurrent Phased Development development RAD (Rapid Iterative and Application Incremental Development)
