Conceptual queries using ConQuer-II, ConQuer-II, and a new tool, ActiveQuery, has been developed with an improved interface. ConQuer-II‘s new features such as arbitrary correlation and subtyping enable it to be used for a wide range of advanced conceptual queries.

The next step in the evolution of automated database design tools is to incorporate knowledge and reasoning capabilities to support this higher level of participation. Doing so, requires some understanding of what d

Over the last few years, object-oriented paradigm has emerged as the natural foundational technology for reuse approaches, leading to the development of a number of reusable artifacts at different levels of abstraction and granularity. This research focuses on artifacts at one le

This explain why almost all conceptual modeling languages have developed a special, easy-to-use syntax (language features) to state the most common constraints. Most features (often wit

Towards Digital Optical Networks because to properly model applications that need incremental design and experimentation (such as CAD, software design process), the evolutionary histories of the schema objects should be traceable. In this paper we propose a method for managing schema changes by exploiting the functionality of a te
