Managing Entity Versions within their Contexts: A Formal Approach
نویسندگان
چکیده
A formal model (concepts and operations) for multiversion databases is presented. It is based on the DBV approach CJ90], which allows the management of entity versions within their context. The problem of reading and comparing complex object versions is presented. The model allows to better understand the potential of the DBV approach, and will be used as a framework for new multiversion functionalities.

متن کاملContext Dependency Management in Ontology Engineering: A Formal Approach
A viable ontology engineering methodology requires supporting domain experts in gradually building and managing increasingly complex versions of ontological elements and their converging and diverging interrelationships. Contexts are necessary to formalise and reason about such a dynamic wealth of knowledge. However, context dependencies introduce many complexities. In this article, we introduc...
