This solution is not the final solution for our problem, because we assume that we can define the exact needs of businessmen by providing variables and components on this system. In reality it is almost impossible to be done, because as we know the business needs of businessmen are different to each other and we can't predict exactly the businessmen needs because of high changes in their needs. Although the preliminary analysis of the system can provide a wide range of variables and components to execute the variable, it is not necessarily for the system to provide the needs of business process in the future.
