1. What’s database?<br />“A database is a collection of information organized to provide efficient retrieval. The collected information could be in any number of formats (electronic, printed, graphic, audio, statistical, combinations). There are physical (paper/print) and electronic databases.”<br />History of database<br />“Database have even existed for thousands of years. However, in the earlier days they were recorded without computers, with crude accounting systems that banks used to use over a 500 years ago. The origins go back to libraries, governmental, business, and medical records. There is a very long history of information storage, indexing, and retrieval.”<br />1960's: Two main data models were developed: network model (CODASYL) and hierarchical (IMS). Access to database is through low-level pointer operations linking records. Storage details depended on the type of data to be stored. <br />1976: The Entity-Relationship (ER) model was proposed for database design giving yet another important insight into conceptual data models. Such higher level modeling allows the designer to concentrate on the use of data instead of logical table structure.<br />Mid-1980's: SQL (Structured Query Language) becomes quot;
intergalactic standardquot;
. DB2 becomes IBM's flagship product. Network and hierarchical models fade into the background, with essentially no development of these systems today but some legacy systems are still in use. <br />Early 1990's: Much development during this period centers on client tools for application development such as PowerBuilder (Sybase), Oracle Developer, VB (Microsoft), etc. Client-server model for computing becomes the norm for future business decisions. Development of personal productivity tools such as Excel/Access (MS) and ODBC. This also marks the beginning of Object Database Management Systems (ODBMS) prototypes.<br />Mid-1990'sThe usable Internet/WWW appears. A mad scramble ensues to allow remote access to computer systems with legacy data. Client-server frenzy reaches the desktop of average users with little patience for complexity while Web/DB grows exponentially.<br />Late-1990's: The large investment in Internet companies fuels tools market boom for Web/Internet/DB connectors. <br />Early 21st century: Decline of the Internet industry as a whole but solid growth of DB applications continues. <br />-2065655-244475<br />Personal conclusion: A database collects information, and organize it, for an easily management. Collect information could be electronic or physical.<br />Over 500 years ago the databases had been developed in libraries, governmental business, medical record, etc. But in 1950, the databases had been introduced in electronic information, because is more easier, clean, etc. during 1950 and 1990, people develop some databases programs, and own designs. <br />Bibliografía BIBLIOGRAPHY Library learning, (2009), database, recuperado el 24 de Agosto de 2010, de http://www.usg.edu/galileo/skills/unit04/primer04_01.phtml Ezine articles, (2010), database history, recuperado el 24 de Agosto de 2010, de http://ezinearticles.com/?The-History-of-Database-Management-Systems&id=904394Ashortdatabase, (2010), database history, recuperado el 25 de agosto de 2010, de http://math.hws.edu/vaughn/cpsc/343/2003/history.html <br />
