摘要：As the data grow day by day in database, it becomes difficult to handle it. One solution is to use cloud computing. The data are stored in different storage space on the servers. In this paper, the graphs are created by using two methods. One method is statistical information and second method is Pareto function. When the user enters the query in its own virtual machine, the result is found using statistical size estimation formulae used for simple query and complex query such as conjunction, disjunction and negation. After finding the values, then a graph is created for relate the size with money using histogram.
