Chronology of Database History
1960s : Computerized
database started in the 1960s, when the use of computer became more a
cost-effective option for private organizations. There were two popular data
models in this decade: a network called Conference/Committee on Data Systems Languages (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 Internasional Business Machine (IBM) to help
American Airlines manage its reservations data
1970s to 1972: E.f. Codd
published an important paper to propose the use of a relational database model,
and his ideas changed the way people thought about databases. In his model, the
database’s schema, or logical organization, is disconnected from physical
information storage, and this became the standard principle for database
systems.
1976: A new database
model called Entity-Relationship, ER, was proposed by P.Chen this year. This
model made it possible for designer to focus on data application, instead of
logical table structure.
1980s: Structured Query
Language, SQL became the standard query language.Relational database
system became a commercial success as the rapid increase in computer sales
boosted the database market, and this caused a major decline in the popularity
of network and hierarchical database models. DB2 became the flagship database
product for IBM, and the introduction of the IBM PC resulted in the
establishment of many new database companies and the development of products
such as PARADOX, RBASE 5000, RIM, Dbase 3 and 4, OS/2 Database Manager, and
Watcom SQL
Early 1990s: After a
database industry shakeout, most of the surviving companies sold databse
products at high prices. Around this time, new client tools for application
development were released, and these included the Oracled developer,
PowerBuilder, VB, and Management System, or ODBMS, were created in the early
1990s.
Mid 1990s: The advent of
the Internet let to exponential growth of the database industry. Average users
began to use client-server database systems to access computer systems that
contained legacy data.
Late 1990s: Increased
investment in online businesses resulted in a rise in demand for internet
database connecters, such as Front Page, Active Server Pages, Java Servelets,
Dream Weaver, ColdFusion, Enterprise Java Beans, and the Oracle Developer 2000.
The use of cgi, gcc, MySQL, Apache, and the systems brought open source
solution to the Internet. With the increased use of point-of-sale technology,
online transaction processing and online analytic processing began to come of
the age.
2000s: Although the
internet industry experienced a decline in the early 2000s, database
applications continue to grow. New interactive applications were developed for
PDAs, point-of-scale transactions, and consolidation of vendors. Presently, the
three leading database companies in the western world are Microsoft, IBM, and
Oracle.
