Downsizing Applications from Mainframes to Client/Server
Source: Software World Digest Published: Nov 1992
George Schussel, Chairman of Database World reviews the issues in migrating mainframe applications to the client/server world. Several caselets are discussed. Some text from the article follows:
Let’s first look at the technical process involved in building a client/server approach. Here, we confront a very different architecture- one that places applications on desktops and data on shared servers. Jim Davey, Senior Consultant for DCI, has been developing a new analysis approach for the client/server environment (an article from Jim is in the works). Regardless of the analysis approach used, it is clear that the native I/O code that once resided in the application will now be removed and/or executed on a different computer. So the first step in a conversion to client/server computing is to re-analyze data I/O and recode to accommodate any necessary changes.
