National Address Database (NAD) on the grid

Address has immense importance to every citizen. This has led to the creation of national address database (NAD), which will allow every citizen to have a valid and verifiable address and also allow diversified services to be provided to them. Traditionally, national address databases have been built and maintained at a single central location. Centralized systems of this sort have inherent drawbacks: single point of failure, congestion and low scalability. To overcome these flaws our research focus is to develop a system with NAD in a grid environment. We have implemented NAD in both centralized and grid environment and done a comparative study between them. In our research we have built a test bed that describes the computational environment in which the comparison is performed. This paper includes proposed grid system architecture for NAD, a table and a graph to show the comparison.
