On temporal versioning in object oriented databases.

Lu, J.; Barclay, Peter J.; Kennedy, Jessie

Abstract

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 space. It supports historical versions and alternative versions of objects at instance level and as well as schema level. as how these different solutions can be combined have not yet been tackled. Many applications require databases that support both temporal data and version management (such as design of engineering objects). Figure 1 shows a Car-Manufacturing Database. There are several types of lock which can be used in this car model. These locks are an alternatives of each other and valid at same time. The historical information of engine design is important, the updated data is need to be preserved. It is considered historical (temporal).
