Data center is an essential support system for an enterprise business supporting online social networking, computation intensive applications, web services and scientific computing. In order to offer proper storage, efficient functioning of applications and computational power, availability of efficient data center infrastructure is necessary. Nowadays, multi-tier approach for accumulation of different processes on same machine is being widely used by companies. Different tiers, which are used for communication over the network include application, web-server and database. Data modeling is an important aspect of record keeping in an enterprise as it is basically representation of data structures, which are required by a database. Data modeling and simulation is adopted to offer better results ranging from computation to architectural designs. Moreover, in order to deliver crucial decisions efficiently in time, development of cost effective modeling and simulation techniques is required. Thus, data modeling and simulation are important aspects of technical decision making in an enterprise.
