The History of Databases

The first time the term database heard was at a conference in California in 1963. A database is a wealth of information that is collected or structured.

Its origins are from of old, where there were already libraries and all kinds of records, also used to gather information on crops.

They began to develop when it became necessary to store large amounts of information or data. The concept of databases has always been linked to the computer.

In 1884 Herman Hollerith design automatic punch card machine, to this fact he began to create a tabulating machine based on punch cards.

In the early 50's origin is given to the magnetic tapes, this served to replace the information needs of new industries.

In the 60s, they lowered the prices of computers so that they could acquire and use popular discs. At this time also they began the first generation of network databases and hierarchical databases. During this time IBM and American Airlines also joined to create Sabres, an operating system that controlled flight reservations, passenger information and transactions.

Later, Charles Bachman created a new type of database and this allowed the creation of a standard in database systems thanks to invention of new languages ​​of information systems.

In the 70s, a British computer scientist, called Edgar F. Codd, said the relational model while published a series of rules for relational database systems; Following this came the second generation of Management Systems Databases.

Thanks to the work of Edgar F. Codd, Larry Ellison developed the Relational Software System, although it is now known as Oracle Corporation, creating a management system relational database with the name of the company.

At the age of 80 a query language for accessing databases that allows queries to retrieve relevant information from a database and make changes easily created; besides examining large amounts of information and detail leaves several types of operations against the same information.

During this time SQL started to become the industry model; the relational database tables with their system could compete with hierarchical and network databases.

In the 90s, they investigated the databases oriented objects. They have been quite successful in implementing complex data in the fields where relational databases have not been able to function effectively. And tools such as Excel and Access were created.

So the third generation of management systems database was created.

At this time also it began to incorporate new regular expressions, recursive queries and some object-oriented features. Besides the opportunity to SQL can be used simultaneously
