Abstract : |
This paper discusses aspects of the Change Oriented Versioning (COV) model, which provides a uniform version concept rather different from the more traditional models. Its main goal is to give users and administrators a more flexible, yet simpler, way to manage changes in large and complex sets of data. In addition to a description of our model, we here add some simple guidelines about how we think it will be used, and describe some of our recent work, not previously presented. We also discuss briefly its use in our work on cooperating transactions. One recent breakthrough in COV is that we have now designed and implemented a versioning "engine " which is independent of the data model being used. 1, |
