WHAT IS ORACLE?
Oracle database often called as Oracle RDBMS, OracleDB, or simply Oracle is a relational database management system, developed and marketed by the Oracle Corporation. The Oracle Corporation is a software company, also known as one of the biggest providers in the database business. It has earned its reputation because of various reasons. The Oracle database is the first to support SQL. And not only that, SQL has since grown as an industry standard. Microsoft’s SQL Server is the rival that the Oracle database competes with, thus giving it some more reasons to endeavour for being one of the most esteemed and extensively used relational database engines.
After being developed in 1977 by Lawrence (Larry) Ellison and his two friends and former colleagues, Oracle database currently operates on the most influential platforms like Windows, UNIX, Linux and Mac OS. Designed for enterprise grid computing, it is the first database that presents the most adaptable and cost-effective approach to manage data and applications. There are various editions of the Oracle database that certainly includes, Enterprise Edition, Standard Edition, Express Edition and Oracle Lite.
Enterprise Edition is known to be an exceptionally robust and reliable edition, thus offering some unique yet important features of superior performance and remarkably solid security. When it comes to Standard Edition, it has its own advantages which ultimately provides the base functionality for users. The standard edition does not require the Enterprise Edition’s exceptionally robust package. Much like the other two editions of the Oracle database, Express Edition also known as XE is also designed for some unique properties, thus making it as a lightweight and free edition. It is also one of the limited Windows and Linux editions. The fourth edition of Oracle database was developed for mobile devices, thus giving it the name Oracle Lite.
