A flat file database describes text any of various means to encode a database model (most commonly a table) as a single file (such as .txt or .ini).

Welcome. In the following series of articles a specific environment in the many and varied realms of Information Technology environments will be explored in a little detail. This is the domain of the RDBMS, or Relational Database Management System. Such systems have evolved, in the course of time, due to the demand for the services that these systems provide. Also considered in these articles is the parallel requirements of IT Management practices as the decades brought one wave of technological change after another. When the first cars appeared, they were often accompanied by a stand-by mechanic with a toolbox in hand riding on the running boards and ready for any roadside repairs.

Event Consequence Pre-1960s 1945 Magnetic tapes developed (the first medium to allow searching). Replaced punch cards and paper tape. 1957 First commercial computer installed. 1959 McGee proposed the notion of generalized access to electronically stored data. 1959 IBM introduced the Ramac system. Read data in a non-sequential manner, and access to files became feasible.

What has happened, where are we, and where do we go? Focusing on OODBMS, ORDBMS and orthogonal persistent JavaTM (PJama)

Ancient Times: Human beings began to store information very long ago. In the ancient times, elaborate database systems were developed by government offices, libraries, hospitals, and business organizations, and some of the basic principles of these systems are still being used today. 1960s: Computerized database started in the 1960s, when the use of computers became a more cost-effective option for private organizations. There were two popular data models in this decade: a network model called CODASYL and a hierarchical model called IMS. One database system that proved to be a commercial success was the SABRE system that was used by IBM to help American Airlines manage its reservations data.

Ancient to modern: The origins go back to libraries, governmental, business, and medical records. There is a very long history of information storage, indexing, and retrieval. Don't ignore this history, there is usually something to learn from these folks and their success and failure. Lots of online stuff (and there is lots) does not guarantee quality of data or search technique. Good design principles goes way back and lots is known now about how to make good designs that lead to better reliability and performance.

Life today is highly dependent on computers - they do most of the important work and are found everywhere - from homes, to police stations, government institutions and military facilities. However, the computer would have never been so popular and widely spread if it was not for the Internet.

The Macintosh, or Mac, is a series of several lines of personal computers designed, developed, and marketed by Apple Inc. The first Macintosh was introduced on January 24, 1984; it was the first commercially successful personal computer to feature a mouse and a graphical user interface rather than a command-line interface. The company continued to have success through the second half of the 1980s, only to see it dissipate in the 1990s as the personal computer market shifted toward the "Wintel" platform: IBM PC compatible machines running MS-DOS and Microsoft Windows.

AltaVista, the Google of its day, is now to be gobbled up by Overture. It's a famous name that's seen better days. But AltaVista's not the only major search player to have faded, as years have gone by. Come along and see the early search engines that have died, those that have been transformed, who's survived and how the "new" players that are no longer so young are doing.
