Intelligent support for retrieval and synthesis of patterns for object-oriented design, software industry. 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

A conceptual development framework for temporal information systems,proach aiming to do this accurately must offer support for data changing over time. This paper presents a development framework for Temporal Information Systems. It is based on a Fact Based Model with time support. The mapping of the model onto a relational database is described and an algebra for i

Temporal features of class populations and attributes in conceptual models,ome logic-based language. Unfortunately, the resulting formulas may be complex, error-prone and difficult to read. 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

Managing schema evolution using a temporal object model, 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

Distributed object repositories: concepts and standards,ration, repository architectures and distributed heterogeneous computing. A repository is the basis for data/object sharing and integration for application as well as business objects in an information systems environment..This paper discusses object oriented repository architectures influenced by O

Conceptual queries using ConQuer-II,at allows users to formulate queries naturally in terms of elementary relationships, operators such as “and”, “or”, “not” and “maybe”, contextual for clauses and object-correlation, thus avoiding the need to deal explicitly with implementation details such as relational tables, null values, outer jo
