Abstract
Abstract An expert system is used to design a computer network comprising hardware platforms, applications, data bases, user interfaces, etc. The expert system initially displays questions and receives responsive information from a user as to characteristics of backend data bases and whether copies of said backend data bases should be stored in respective frontend data bases. In response, the expert system "builds" one of a predetermined set of backend models which corresponds to the information. Next, to reduce complexity, the expert system identifies two or more of the frontend data bases of compatible type that can be merged together and then displays questions and receives responsive information indicating whether the mergers should be made. Next, the expert system displays questions and receives responsive information as to characteristics of frontend components including an intermediate server. In response, the expert system builds one of a set of predetermined frontend models which corresponds to the information. Next, the expert system identifies a function of the intermediate server that can be performed on a backend platform within the backend model. Next, the expert system displays questions and receives responsive information whether the function should be performed on the backend platform, and updates the frontend model accordingly. Next, the expert system displays questions and receives responsive information as to characteristics of connections between the updated frontend model and the backend model. In response, the expert system determines a final design of the computer network based on the connection information, backend model and updated frontend model.
