Design And Implementation Of Well Side Quality Monitor And Control Network System

Client server architecture(C/S) is used in Traditional database applications usually. This structure is technically a very mature and very broad application, but the structure of this system has its shortcomings Department, such as inquiries can not be able to share, even if the same request send by two customers at the of the server needs two inquiries, and commercial-value search algorithms is stored in the client; inefficiencies result by heavy burden of of Database Server. Adding another server between the server and client with a special algorithm for temporary storage and query search will be a very good solution to the problem. Customers will be able to share the provisional results of the inquiry avoid accessing database server, thereby reducing the burden on the server. At the same time, clients can not see the secret search algorithms in the client.The emergence of distributed systems from the traditional C/S architecture brings a number of drawbacks. In addition adding another server between the server and client with a special algorithm for temporary storage and query search will be a very good solution to the problem. This is the working principle of distributed systems. PowerBuilder simplify the development of distributed applications.When the current background server services needed by end users, the core of the C/S structure merely issues request, and the server implementates the corresponding function when acceptting the request, and responses the part of the data to meet the conditions of...
