Investigate a CASE tool, such as those offered by Computer Associates (www.ca.com), Oracle (www.oracle.com), Borland (www.borland.com), or IBM (www.ibm.com). On what system development methodologies is the tool based? What types of system models can be built with the tool? How is an analysis model translated into an implementation model? What programming languages, OSs, and DBMSs does the back-end CASE tool support? What deployment environments are supported?
