What is software? #Computer programs and related documentation What are the attributes of good software? #Good software should be maintainable,dependable and usebal. What is software engineering? #That is concorned with all aspect of software production. What are the fundamental software engineering production? #Software Development #Software Validation #Softwae Evolution #Software Specification What is difference between software engineering and computer science? #Computer Science; #Software Engineering; focuses on theory and fundamentals developing and delivering useful software What are the key challenges facing software engineering? #Developing reliable software #Coping with increasing diversity. Software Products Generic Products:Are marketed and sold to any customer Customized Products:That is used by a specific customer Crucial Attributes of a Good Software Maintainability:Software should be written/developed in such a way so that it can evolve to meet the changing needs of customers. Dependability and Security:Dependable software should not cause physical or economic damage in the event of system failure Efficiency:Efficiency therefore includes responsinevess,processing time etc. Acceptability:Software must be acceptable by the end users,which is designed for them. Software Process Activities Specification: Where customers and engineers define the software details Development: Where the software is designed and programmed. Validation: Where the software is checked to ensure that it is what the customer requires. Evolution: Where the software is modified to reflect changing customer and market requirements General issues that affect software 1)Heterogeneity: 2)Business and Social Change: 3)Security and Trust 4)Scale: Software Engineering Diversity Method and tools change acc to; 1)The type of application being developed 2)The requirements of the customer 3)The background of the development team Application Types 1)Stand-alone Apllications:Run on a local computer,do not need to be connected to a network 2)İnteractive Transaction based Applications: Execute on a remote computer and are accessed by users from their own PCs or terminal 3)Embedded Control Systems:These are software control systems that control and manage hardware devices. 4)Batche Proccesing Systems:These are business systems that are designed to process data in large batches 5)Entertainment System: Systems that are for personal use 6)System for modeling and simulation: 7)Data Collection System 8)Systems of Systems Software Engineering Principles 1)A managed and understood development process is necessary. 2)Dependability and performance are important criterias. 3)Understanding and managing requirements is necessary. 4)You can reuse software 5)Effective use should be made of available resources. Web-based software engineering=Software Engineering Principles Three key characteristics of the engineering of web-based software engineering Software reuse is the principal approach for constructing web-based systems Requirements for those systems can't be completely specified in advance User interfaces are constrained by the capabilities of web browsers. Software Engineering Ethics: A set of principles that set out, in a general way, standards of expected behavior for professional software engineers. Download 17.96 Kb. Share with your friends:
