User interface and database design for software database of the Computer Aided Prototyping System (CAPS)

摘要

CAPS (Computer Aided Prototyping System) is an integrated set of software tools that generate prototypes directly from real time requirements. The success of CAPS depends on being able to generate the prototype quickly so that it can be evaluated, leading to the construction of a program built on true requirements thereby resulting in a better software product. The key to developing prototypes quickly is having a significant software base to choose reusable components from. The problem with the current version of CAPS is that there exists no software base storage facility. This thesis utilizes the Ontos database to build the object oriented conceptual design for the data object repository and uses TAE to create the graphical user interface to access the repository. It further explores various searching techniques to deterniine the best possible implementation of the repository search engine. The results of this thesis are a conceptual design that can be used to implement the software base and an interface which provides a fluid, intuitive, interactive environment in which the user will be able to manipulate the database when actually built It further identifies the multi-level filtering technique as the best candidate for searching the database, because of its high recall, high precision, and reduced search time.
