“…The Temporal Versions Model (TVM) is proposed as an object-oriented (OO) data model that extends a version model by adding the temporal dimension to the instance versioning level [8]. Indeed, the user can model the database considering the design alternatives as well as the data evolution.…”

This paper presents a language designed for the description of both temporal schema versioning and schema modification in object-oriented databases. The language supports temporal and versions features in both schemata and data levels. An extension of the ODMG standard is presented in order to incorporate temporal and versioning features into ODL language to properly manage the schema evolution mechanism. Thus, this proposal improves the database environment with temporal and versioning features concerning database modification. The solution to the problem is shown to be feasible since it is defined in terms of the ODMG standard.

Temporal Versions Model (TVM) is an object-oriented data model with versioning facilities, allowing revisions and project alternatives, and temporal features, used to maintain the history of the system evolution. This paper presents TVM under a Software Configuration Management (SCM) perspective, compares this model with available SCM tools, and describes why TVM is adequate to be used as the basis of an SCM environment. A modeling example and the implementation of TVM on a commercial Database Management System (DBMS), which is an ongoing work, are also presented.

“…One of these, the Versions Model [4], adds to object oriented models some concepts and mechanisms for the definition and manipulation of objects, versions and configurations. To allow the historical representation of changes, this model was extended with temporal features, resulting the Temporal Versions Model -TVM [10]. TVM allows storing object versions, and for each version, all the historical changes on dynamic attributes and relationships are also maintained.…”

Abstract. In this paper, an analysis of the schema evolution process in object oriented databases is made using an object oriented data model that supports temporal features and versions definition -the Temporal Versions Model. A meta schema structure is defined to store information concerning to evolutionary schema states, as well as their classes, attributes and relationships. An implementation proposal is presented, combining specification and manipulation mechanisms including version and time concepts. Two alternatives are defined for the database extension management: multi-pool for schema versioning and single-pool for class versioning. Concerning the physical representation, both approaches can be used in the same application.
