Software testing strategies. It provides initial architectural design specification of side effects exception handling processing algorithms and data representation. Software testing strategies ppt chapter 9.
Software design yields three levels of results. Software design and architectures structure charts based on the fundamental notion of a module. It tries to specify how to fulfill the requirements mentioned in srs. The information on levels 23 and 4 can be included in successive steps.
A structure chart is a collection of one or more node labeled rooted directed acyclic graphs. These allow data flow constructs and variables to be identified before coding begins. In addition the notation should enhance code to ability so that code does in fact become a natural by product of design. Powerpoint html lecture 6 requirements analysis and specification powerpoint html lecture 7 management ii.
Data flow diagram is graphical representation of flow of data in an information system. Let us see few analysis and design tools used by software designers. Academiaedu is a platform for academics to share research papers. Software analysis and design is the intermediate stage which helps human readable requirements to be transformed into actual code.
Component based software engineering. Component based software engineering ppt chapter 10. Design notation pseudocode flow charts and structure diagram are techniques that are used to design software. Design and implementation ppt chapter 8.
Pseudo code notation pseudo code notation can be used in both the architectural and detailed design phases. Each graph is a process. Distributed software engineering ppt chapter 11. Design concept the beginning of wisdom for a software engineer is to recognize the difference between getting a program to work and getting it right.
Used in structured systems analysisstructured design ssasd. Fundamental software design concepts provide the necessary framework for getting it right 3.
