Metalevel decomposition in AL-1/D, way. To modify the system flexibly, it is necessary to represent various abstraction levels, from the programing language level to the OS level, as well as user‘s multiple views, such as the view where the distributed environment is transparent and the view where that is not transparent, in a progr

Kernel structuring for object-oriented operating systems: The Apertos approach,taobject separation, a means of constructing an object-oriented operating system and its kernel. This method divides the implementing system facilities and applications into two types: objects and metaobjects. This paper presents the concept of object/metaobject separation and discusses why object/m

Object database systems: Functional architecture,pted overall architecture. The goal of this paper is to describe this architecture..An object database system supports an object database model. This model can be decomposed into four different aspects: data, behavior, persistence and naming..An object database system consists of a database engine s

An object-centered approach for manipulating hierarchically complex objects,uery algebra. Extensions of the object model are mainly based on a separation of structural and semantic elements in modeling complex objects, including a general distinction between aggregation reference and association reference, an introduction of type inheritance into aggregation hierarchies and

Towards the unification of views and versions for object databases, of views and versions have not been adequately explored. This paper introduces the concept of a virtual database to unify these two notions in the object database context. The semantics of virtual databases is presented, and a mechanism for interactively creating and deleting virtual databases and

Refactoring and aggregation,ied are those based on inheritance, on reorganizing a class hierarchy. However, aggregation is a relationship between classes that is just as important as inheritance, and many changes to an object-oriented design involve the aggregate/component relationship. This paper describes some common refacto
