Mapping the UML to the Zachman Framework

This article offers an overview of the Zachman Enterprise Architecture Framework (ZEAF) and examines how the Unified Modeling Language (UML) can be used in describing enterprise architecture. The ZEAF is a classification scheme that organizes descriptive representations into a matrix of six distinct stakeholder perspectives and six unique concerns or aspects yielding a normalized approach in which, as a rule, particular cell content cannot be found in more than one cell. This paper presents a comparative review of four approaches for mapping UML onto ZEAF, which despite the above rule, use the same diagram types differently. At first, this appeared to be a problem, but our analysis discovered that it is result of UML’s rich and divers notation. This paper also attempts to answer several questions related to these different mappings recognizing an opportunity to extend ZEAF into a multidimensional representation

A structured specification technique for hypermedia systems

At the end of the 20th century, the single most revolutionary change in information technology will be the availability of electronic information libraries for multimedia users. Hypertext, multimedia, and hypermedia are already established research and application areas. However, very few works deal with the problem of specifications representation for hypermedia. The Extended Warnier Diagram (EWD), an acceptable diagramming technique for specifying hypermedia documents, is introduced. Such a specification should play the role of a general analysis and design representation. The EWD allows many extensions. Since hypermedia is among the fastest growing sectors of computer technology, it is realistic to expect many new features of this immature technology. It is very important to follow that expansion with new extensions to the EWD when necessary

User interface driven system design

This study attempts to look at the internal and external factors which result in improved interior design project management through the proposal and empirical validation of a theoretical model. The model incorporates three major dimensions: users’technology readiness, their perceptions of information system quality, and project management effectiveness. Sample data collected from 50 interior design companies located in north, central and southern urban cities in Taiwan (n = 497) were analyzed using structural equation modeling (SEM). Results showed that both users’ technology readiness and information system quality have positive effect on project effectiveness. Specifically, technology readiness influences project management effectiveness indirectly through information system quality, indicating that it is crucial for organizations to invest and enhance quality technological performance support tools in conjunction with fostering users’ acceptance and readiness of technology adoption and application
