A fault tolerant access to legacy database systems using CORBA technology

This work presents a software-implemented fault tolerance approach for building a reliable database application in a CORBA environment. Database applications have functional requirements and non-functional requirements, such as dependability and performance. We provide an architectural framework that makes it possible to separately address these issues. More precisely, it is possible to: i) guarantee functional properties by incorporating existing software modules, and ii) add dependability to the resulting system via proper programming of the business logic of the Middle Tier. The legacy software is integrated in the new system with no changes. This strategy can effectively reduce the development effort for building a reliable system, while protecting the investment in legacy appliContact author's contact info: Dipartimento di Informatica e Sistemistica, Via Claudio 21
