CS565 Advanced Software Development Lecture 23, 2006 CASE

Documentation Legacy of analysis and design decisions - offer traceability back to requirements. Documents should be allowed to evolve together with the product releases. What? requirements, analysis, design, implementation end user manual(s) planning/management reports, etc. A traceability matrix can match design elements with requirements.

Writing Tools Document production/ desktop publishing tools CASE/ Self-documenting systems Library support - access Writing Documentation Guidelines (from Bahrami, OOSD, p139) Common cover sheet - doucument id., version, author(s) Make document accessible Use familiar vocalulary Make documents as short as possible Organise e.g. Chicago manual of style/ Struck Jr. style guidelines

Computer Aided Software Engineering Computer tool to assist developrers Modelling and documentation Sometimes can generate system implementation In the mid-1980s a number of separate tools became prominent for analysis and design (Entity Relationship diagrams, Data Flow Diagrams, and Program Design). This often entailed manual conversion of the output of one tool to provide the input of another. This lead to CASE tool integration. Horizontal integration - tools connected at the same stage of the software development lifecycle (SDLC). Vertical integration - tools connected at different stages of the SDLC.

Degree of Support Many CASE tools simply act as repositories of models and documents. They so not assist in the creative part of modelling. Some CASE tools attempt to provide more assistance, ranging from simple prompts through to syntax/model checking. Ways to use CASE As independent toolkits to be utilized in a way decided by development team. As part of a methodology
