Aspects of Version Management of Composite Objects

Résumé du livre

Abstract: "An important aspect of object-oriented database systems is the ability to build up composite objects from object parts. This allows modularity in the representation of objects and reuse of parts where appropriate. It is also generally accepted that object-oriented database systems should be able to handle temporal data. However little theoretical work has been done on temporal behavior of composite objects, and only relatively few systems attempt to incorporate both historical information and composite objects in a multi-user environment. We argue that the support for handling temporal information provided by other systems addresses only one of two important kinds of historical information. We describe the notions of temporal history and edit history
