What is an Oracle Database?

An Oracle Database is a Relational Database Management System (RDBMS) developed by Oracle Corporation. The Oracle Corporation is a U.S. based multinational technology company headquartered in Northern California. Oracle database was the first commercially available RDBMS in 1979. According to DB-Ranking Engine, the Oracle, MySQL and SQL Server are the most popular relational databases in the industry.

A Relational database consists table with relevant data to ensure that the data is organized in a way so that it is readily available by the user who has permission to access the data. The information in the tables are organized, and a user can be retrieve, update, store, delete and manage those data based on their access level.

A Relational Database Management System contains tables, also known as entities, with data and maintains information regarding the relationship between the tables. A table is made up of one or more COLUMNS, and ROWS. A column name in a table represents a unique property of the entity. Each row in a table contains a unique (no instance of duplicate rows) value. In a relational database, each table is related/linked to another table by having one or more column(s) data being linked. The data in a database is accessed using Structured Query Language (SQL).

To understand “Database” concept in-depth, one would have to take one or more courses that give students the hands-on experience in creating and managing data using Oracle database. Some of the recommended courses would be SQL, PL/SQL and Database Administration (DBA). These courses are taught at multiple locations.
