Looking back to Client-Server
More expensive, but had some advantages
InfoWorld in the 90s
Before the Web, tools like PowerBuilder, FoxPro, and Clipper were key parts of infrastructure creation, and SQL made possible a clean separation of client and server processing.
Fat clients made some happy customers
Sophisticated client software gave businesses highly customizable tools for requesting and processing record sets from central data stores.
Lower impact on network traffic
Clients might communicate back and forth with servers, but record set caching could minimize continual exchanges of redundant data.
Lower impact on server processing
Servers, at least at first, could focus on storage and retrieval, not more processor-intensive algorithms.
Term mostly about data, but same architectures used for documents
File servers used similar approaches, with file systems instead of database tables.
