A Temporal Versioned Object - Oriented Data Schema
This paper describes in a formal way a data schema model which introduces temporal and versioning schema features in an objectoriented environment. In our model, the schema is time dependent and the history of the changes which occur on its elements are kept into version hierarchies. A fundamental assumption behind our approach is that a new schema speci cation should not de ne a new database, ...
متن کاملTemporal Object-Oriented Data Model for the Schema Modification
A temporal database management system is being considered as an important DBMS in new database applications such as engineering databases, VLSI, and CAD. Much researche on temporal databases, temporal query languages and temporal modeling techniques have been proposed. However, thus researche has not considered the schema modification problem in a temporal database yet. In this paper, we propos...
متن کاملAn Access Mechanism for a Temporal Versioned Object-Oriented Database
Object-Oriented database systems (OODBMS) are well known for modeling complex and dynamic application domains. Typically OODBMS have to handle large and complex structured objects whose values and structures can change frequently. Consequently there is a high demand for systems which support temporal and versioning features in both objects (or database population) and schema. This paper present...
متن کاملA Temporal Object-Oriented Data Warehouse Model
The data warehousing approach intends to exploit a very large volume of data to make relevant decisions. In this paper, we deal with objectoriented data warehouse design. More precisely, we present an object-oriented data warehouse model, integrating temporal and archive data. We provide functions allowing the administrator to specify a data warehouse from a global source schema.
