The motivation of this work was the very few approaches which attempt to provide methods and tools for designing inheritance graph in object databases [.], and object software[.]. To address some limitations found in our work, we propose a new method whose principles are: (i) From a binary rela

Introduction to an Urban Ecosystem Approach,or novel techniques and mechanisms which can provide an efficient retrieval facility of the voluminous data stored in the databases. While “content-based” retrieval provides a direct and an intuitive approach for video data access, it is inadequate from efficient video data management viewpoint. Thi

In this paper, we characterize the set of valid type configurations, taking into account the constraints defined by specializations and generalizations. We also

Leakage Resilient Cryptography in Practiceity-Relationship (ER) models have been proposed that are intended to model the temporal aspects of database conceptual schemas. This work gives a logical formalisation of the various properties that characterise and extend different temporal ER models which are found in literature. The formalisation

Information Security and Cryptographyly, we have developed a general framework to support the schema transformation process, consisting of a hypergraphbased common data model and a set of primitive schema transformations defined for this model. Higher-level common data models and primitive schema transformations for them can be defined
