Essay: Brief History of Oracle DatabaseCompanies / Technology Apr 12, 2017 - 04:24 PM GMT
The Oracle Database is the top object-relational database management system in its category, and its dominant market position makes It one of the world’s most important database management systems. The history of the Oracle Database can help us to understand the origins of the ORDMS and the important role in plays in today’s information technology environment.
In order to understand the origins of the current Oracle Database, we should trace the history of the object-relational database management systems from their origins in relational database management systems, and how this change was entwined with the history of Oracle over the past several decades.
The Origins of ORDMSs
Object-relational database management systems emerged in the 1990s by adding object concepts to pre-existing relational database systems. The first ORDMS was the Postgres system at UC Berkeley, which in turn gave rise to Illustra and PostgreSQL. As the 1990s progressed, these early ORDMS systems developed into the wide array of systems that we know today, making the Oracle ORDMS the most robust and the most adaptable ORDMS on the market today.
As these systems were under development, they intersected with the development of the Oracle Corporation, a company that was founded by Larry Ellison, Bob Miner, and Ed Oats as Software Development Laboratories in 1977. Ellison and his cofounders had been inspired by a 1970 paper by Edgar F. Codd that outlined what would become relational database management systems. As a result of the success of relational database management systems, SDL changed its name to Relational Software, Inc. in 1979. Three years later, the company became Oracle Systems Corporation and in 1995 Oracle Corporation. One of the key innovations of Oracle was programming in C programming language, making it easier to integrate their systems with various operating systems. Ellison named the company Oracle after the code name of a secret project funded by the CIA that he had worked on during his time with Ampex.
Oracle’s database was the first commercially viable RDBMS. When its first database was released in 1979, the company launched it as “version 2” because they were concerned that consumers might view a “version 1” as untested and unready. The version 2 database was so popular and successful that the company temporarily named itself after its most successful product. Version 3, released in 1983, was the first to use the C programming language, increasing its utility and adaptability.
Version 4 added the ability to create reports as the result of query. Version 5, released in 1985, began to adapt the database system to the internet and introduced new security protocols. Version 6 in 1988 allowed users to back up the database while it was live and running, rather than having to shut it down prior to beginning the backup process.
As the company’s database developed, it took on new features, becoming portable and eventually becoming an ORDMS in 1997. In 1998, version 8i made Oracle’s database system the first to be compatible with web technology such as Java and HTTP. In 2001, Oracle added the ability to access multiple databases simultaneously, and in 2003 they expanded their services to include grid computing. In 2007, the Oracle database infrastructure was upgraded to develop a simplified format that was designed to help businesses operate more efficiently. In 2013, Oracle made its databases cloud-compatible to empower users to utilize their services in new and improved ways.
The Importance of Oracle
The Oracle Database is an industry leader in its field, and it makes an important contribution to information technology for businesses and organizations around the world. The Oracle system continues to grow and develop to keep pace with the times, and its innovations set the standards that other companies follow. As Oracle’s database continues to adapt and change over time, so too do the businesses that rely on this technology to stay abreast of the changing nature of the business world.
Oracle has kept head of the competition for four decades, and it has outlasted a large number of companies that came before it and many that followed. Its record of innovation has made the Oracle Database one of the most flexible and the strongest currently available in the marketplace.
