A formal model for temporal schema versioning in object-oriented databases

The problem of supporting temporal schema versioning has been extensively studied in the context of the relational model. In the object-oriented environment, previous works were devoted to the study of the different aspects of schema evolution or (non-temporal) versioning in branching models, due to the traditional origination of the object-oriented model from CAD/CAM and CIM. Nowadays, the com...

A Framework for Managing Schema Versioning in Object-Oriented Databases

An approach to schema modification management is presented which also takes into concern that alternative schema perspectives seems to be needed, in addition to revision-like changes. The primary goal is to support change transparency when the schema is modified, such that existing application programs and objects need not be affected by changes to the schema. The approach is based on explicitl...

Temporal and versioning model for schema evolution in object-oriented databases

model space that consists of the semantic and the temporal dimensions. The evolution of data objects can quickly become intractable if it is not captured and Vocabulary evolution and versioning: ontologies, vocabularies, data level changes that in turn are more schema-specific and dependent on semantics. A formal model for temporal schema versioning in object-oriented databases. Data Knowl. Sch...

On Temporal Versioning in Object-Oriented Databases

This paper describes the development of the data model TVM which contains a new concept, temporal versioning. This generalises the ideas of temporal databases and version management to object-oriented databases. TVM provides a new approach for data modelling and management; it allows the user to define a multi-dimensional temporal storage space and to model the evolution of objects within that ...

Schema Versioning and Class Hierarchy Modifications in Object-Oriented Databases

Schema Modification Management is the ability to perform changes to a database schema when the database may already be populated, and is particularly concerned about how schema changes propagate to instances to retain compatibility objects and their specification. In this paper we argue that the schema versioning approach, which allows for multiple versions of the schema to coexist, is preferab...
