What is distributed function processing?
Here the split occurs in the application functionality, one part going to the client, other to the server. Distributed function applications are the most complex of the three typologies since two separately compiled application programs must be developed. Developers must analyze where each function should reside and what type of dialog must occur between the two programs. The underlying communications facilities may implement either a message-based or remote procedure call (RPC) mechanism for transfer of dialog and data. However, there are many variants of this typology. One variant of the distributed function style is where data management and application function occur at both the client and server. In this instance, data management at the client would include referential, read-only data. Data frequently updated or accessed by many users would reside on the server.
