Soon most information will be available at your fingertips, anytime, anywhere. Rapid advances in storage, communications, and processing allow us move all information into Cyberspace. Software to define, search, and visualize online information is also a key to creating and accessing online information. This article traces the evolution of data management systems and outlines current trends. A prescient 1996 paper predicted much of the NoSQL and web tools we use today... and much more.

"If there was an error in a transaction, it was not detected until that evening’s run against the master file, and the transaction might take several days to correct. More significantly, the business did not know the current state of the database – so transactions were not really processed until the next morning. Solving these two problems required the next evolutionary step, online systems. This step also made it much easier to write applications."
In one site, the COBOL programs written for an IBM-compatible mainframe were 4 pages long, including file descriptions.
The on-line programs using a DBMS ran to 110 pages without any file descriptions that were simply INCLUDEd during compile time.
On-line systems made it much easier to write applications?
They must have some high-quality weed up in Washington state!

The whole thing reads like a paper on data management systems written for a first course in DBMS by a BS (Computer Science) major in his sophomore class.
