7. Software Development Technique S OFTWARE DEVELOPMENT TECHNIQUES General Definition Software development deals with the creation of highly complex and dynamic “systems” Literally SoftWARE means “Soft” HardWARE, which stands for pliable electronics The increase in hardware-capabilities resulted in an exponential increase of potential software complexity 21.05.2008 7 The Brown Pup

8. Software Development Technique S OFTWARE DEVELOPMENT TECHNIQUES Programming Language artificial language that can be used to control the behavior of a machine, particularly a computer defined by syntactic and semantic rules which describe their structure and meaning respectively prominent purpose of programming languages is to provide instructions to a computer 21.05.2008 8 The Brown Pup

11. Software Development Technique S OFTWARE DEVELOPMENT TECHNIQUES 21.05.2008 The Brown Pup 11 Pro Possibility to discover mistakes early save money places emphasis on documentation simple and arguably more disciplined approach structured approach that progresses linearly Con Impossiblity to satisfactoraly complete one step Method falls apart when problem is constantly changing feedback from following phases is needed to complete preceding phases satisfactorily Waterfall Model

12. Software Development Technique S OFTWARE DEVELOPMENT TECHNIQUES Rapid Application Development a very flexible methodology main mechanisms prototyping user feedback best use where a large user community the requirements are unclear high possibility of changes in requirements and features typical chain of RAD process events 21.05.2008 12 The Brown Pup

13. Software Development Technique S OFTWARE DEVELOPMENT TECHNIQUES Rapid Application Development creating by involving the user community in all phases of the creation a user driven design manifestation of Vilfred Pareto's law (80 - 20 Rule) 80% of the costs of a complete system are due to 20% of the features included in the system 21.05.2008 13 The Brown Pup

16. Software Development Technique S OFTWARE DEVELOPMENT TECHNIQUES Computer-Aided Software Engineering tool which aids software engineers to maintain and develop software. basic idea behind CASE is to support each phase of the life cycle with a set of labor saving tools CASE tools either concentrate on supporting the early phases or the implementation phases of the life cycle 21.05.2008 16 The Brown Pup

17. Software Development Technique S OFTWARE DEVELOPMENT TECHNIQUES Computer-Aided Software Engineering Use-Case Diagram describing the external view of the system and its interactions with the outside world Use-cases are typical interactions of actors with the system 21.05.2008 17 The Brown Pup
