Oracle Training in Nepal

Course Duration: 60 hours

Ellipse Institute is Best Computer Training Institute for Oracle Training in Nepal. An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. Oracle Database (commonly referred to as Oracle RDBMS or simply as Oracle,) is an object-relational database management system produced and marketed by Oracle Corporation.

Larry Ellison and his two friends and former co-workers, Bob Miner and Ed Oates, started a consultancy called Software Development Laboratories (SDL) in 1977. SDL developed the original version of the Oracle software. The name Oracle comes from the code-name of a CIA-funded project Ellison had worked on while previously employed by Ampex.
