applications have an intermediate layer, which is used to centrally process application logic. In this way, different customer programs can use the same data and ensure that the data logic is consistent. At the same time, the customer program can be relatively small, because a considerable part of the work is done by the middle layer, which is called a "thin" customer. Thin customers are easier to install, configure, and maintain because it does not need to contain
