Oracle Database is an object-relational database management system (ORDBMS) developed and marketed by Oracle Corporation. Oracle Database is commonly referred. In the early 70’s Dr. EFT Codd, a computer scientist, invented the relational model for database management. The relational model deals with many issues caused by the flat file model or the FMS (File Management System). According to his model, instead of combining everything in a single structure, data is organized in entities and attributes to make it more effecient. Oracle has the SQL (Structured Query Language) and also support PL/SQL (Procedural Language using SQL).

This course is meant for everyone who would like to visualize how information gets stored and delivered to end users and a solid understanding of the Oracle products used in professional job roles.
