In this paper, we propose a model of schema versions for object-oriented databases called RiBS. At the heart of this model is the concept of the Rich Base Schema (RiBS). ...
Users impose schema evolution directly on schema versions, and the effects are, if necessary, automatically propagated to RiBS. ...
Introduction The functionality of schema evolution is one of the important differences between object-oriented database management systems (OODBMS) and relational database management systems (RDBMS). ...

In this paper, we propose a model of schema versions for object-oriented databases called RIBS. At the heart of this model is the concept of the rich base schema called (RiBS). ...
In our model, each schema version is in the form of a class hierarchy view over one base schema, called RIBS, which has richer schema information than any existing schema version in the database. ...
We also wish to thank the referees for their valuable comments and suggestions, especially for referee A, which led to a considerable improvement of the presentation. ...

In the maintenance of software applications, database evolution is one common difficulty. In object-oriented databases, this process comprises schema evolution and instance adaptation. ...
In this example, the database evolution is necessary because the metadata layer (in version 'A') in the object-oriented database system (OODBS) does not follow the new class structure in version 'B'. ...
The database evolution problem, in object-oriented databases, has two parts, each in a distinct data layer: (i) schema evolution, at the database metadata layer and (ii) instance adaptation, at the data ...
