Data access (tutorial session)

Abstract

With an explosion of data on the web, consistent data access to diverse data sources has become a challenging task. In this tutorial will present topics of interest to database researchers and developers building: interoperable middle-ware, gateways, distributed heterogeneous query processors, federated databases, data source wrappers, mediators, and DBMS extensions. All of these require access to diverse information through common data access abstractions, powerful APIs, and common data exchange formats. With the emergence of the web, database applications are being run over the intranet and the extranet. This tutorial presents an overview of existing and emerging data access technologies. We will concentrate on some of the technical challenges that have to be addressed to enable uniform data access across various platforms and some of the issues that went into the design of these data access strategies.
