Integrated Access to heterogeneous databases using forthcoming OSI standards

Integrated access to distributed data managed by heterogeneous database management systems is a critical requirement in most organizations. ISO´s OSI appears to be the most promising systems integration framework for providing integrated access to heterogeneous databases. ISO is currently advancing key standards to meet this requirement. The paper presents a functional overview of these forthcoming database access standards and a strawman architecture for integrated database access. It also discusses the use of these standards for supporting integrated access to nonrelational systems. Practical aspects such as standardization schedule and vendor and user support are also discussed
