One of the biggest challenges that any organization or a business faces is of storage and management of data. The data could be anything and pertaining to anyone – it could be the employee records, sales records, the invoicing details, etc. Computers came across as a boon, to these organizations as it could systematically organize the data and gave the desired outputs required too.
The Origin of DBMS (Database Management System)
The first database management system was found in the late 60s to early 70s. It relatively eased the pressure and gave data in a systematic format. However; the problems were that it was not very flexible and the systems were too complex to be used, they were either network or hierarchical databases. The challenges faced were adding of an application in the existing system or organizing of the data.
A solution to the complexity of system was soon found in the form of relational databases, which was completely based on the theory of normalization.
In the 1970s, E.F.Codd defined the relational data model.
Around four years later, IBM came up with their own project called System/R which was again based on the relational database theory. A query language called “Sequel” was developed; Sequel is the abbreviation of Structured English Query Language. For purely legal reasons, in the later years, this was renamed as Structured Query Language.
In the year 1978, IBM customer sites evaluated a prototype named “System/R”. In a year’s time, the project came to an end with the conclusion that RDBMS as possible commercial product.
Brief history of Oracle
The origin of Oracle was in the late 70s to be precise in the year 1977, when Larry Ellison with his group of friends and his previous co-workers came together and started the consultancy named “Software Development Laboratories” which came to be known as SDL. The original edition of Oracle was first made by SDL. A project funded by which had a code name “Oracle” was used by SDL for the program it developed that is how Oracle was named thus. The very first version of the product was launched two years after the inception, became the first commercial RDBMS to beat IBM. It was later renamed to as Oracle in the year 1980.
Throughout the decade of 80s, a lot of new features were added and the performance was upgraded. Since the prices of hardware crashed, Oracle became the single largest RDBMS vendor, almost monopolizing the market. By the end of 1985, they almost had a record 1000 installations. The demand for relational databases started increasing and becoming acceptable by one and all. Later on the companies started demanding usage of excel sheets, storage of images this led to changing the version and they came up with object extensions. This extension enabled a user to do a variety of other tasks.
Currently it is known as Oracle or Oracle RDBMS, and is completely produced, owned and marketed by the Oracle Corporation. Until the end of the last year, Oracle had a very good presence in the world market for database computing; in fact it was one of the top leaders in Object-oriented Relational Database Management system (see the most common Oracle interview questions)
