A data base is a structured collection of records or data. A computer database relies upon software to organize the storage of data. The software models the database structure in what are known as database models. The model in most common use today is the relational model. Other models such as the hierarchical model and the network model use a more explicit representation of relationships (see below for explanation of the various database models). Reference- Database

Oracle (5)
The concept of the relational database was first described around 1970 by Dr. Edgar F. Codd .Oracle database helps in achieving reliable, flexible, secured and cost effective way to manage information and applications. Oracle offers high performance and scalability, because all computing resources can be flexibly allocated to applications as needed. In oracle the logical and physical structures are separate and thus this helps in physical storage of data can be managed without affecting the access to logical storage structures. Oracle is a major database which along with its added features passes the ACID test, which is important in insuring the integrity of data. Oracle is very much suited for enterprise computing and large database applications.

Learn SQL (9)
The Structured Query Language (SQL) is the computer language in which a user or an application communicates with an SQL-capable database system. SQL database systems include PostgreSQL, MySQL, Oracle, and many others in popular use. The language is standardized by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO), but many database systems provide their own extensions to the standard or do not fully implement the standard. These extensions typically extend SQL functionality into an altogether different programming language or markup language. SQL was first developed in the early 1970s for use with System R, a database system created by IBM.

Database Concepts (8)
In the 1960s, the System Development Corporation, one of the world’s first computer software companies and a significant military technology contractor, first used the term “data base” to describe a system to manage United States Air Force personnel. The term “databank” had also been used in the 1960s to describe similar systems, but the public seemed less accepting of that term and eventually adopted the word “database”, which is universally used today. A number of corporations, notably with IBM and Rockwell at the forefront, developed database software throughout the 1960s and early 1970s. MUMPS (also known as M), developed by a team at Massachusetts General Hospital in the late 1960s, was the first programming language developed specifically to make use of database technology. In 1970, the relational database model was born. Although this model was more theoretical than practical at the time, it took hold in the database community as soon as the necessary processing power was available to implement such systems.
