Various types of transparencies in distributed homogeneous and heterogeneous database systems

Abstract

The architecture of database system becomes more complex day by day as different sites or organizations use different hardware, software, operating system or database. Not only is it about different systems, but also about different locations as same companies establish data centers at various part of the world. Distributed database system can connect the world in a system where a user thinks that it is a single system, but in architecture it is not. This heterogeneity leads to the thinking about the transparency in database management system. As whatever the system is, user need not to know about the internal architecture; they need only the accessibility of their information. And this is what transparency actually means presenting the whole system as a single system to the user and hiding the internal architecture. This paper briefly discusses the various types of transparency that need to be present in different types of distributed database systems.
