Course Description

In 1979, Oracle Corp. was the first company to commercialize an RDBMS platform and remains the leading database provider with a large margin in terms of revenue. Driven primarily by Oracle Database sales, it accounted for 40.4% of global database software revenue in 2016, according to Gartner. It was down two percentage points from 2015, but twice as high as Microsoft’s share of second place.


In the decades since the introduction of RDBMS technology, Oracle has significantly expanded its product portfolio through internal development and numerous acquisitions. It now also sells several other databases, business applications, data analysis software, middleware, computer systems, data storage equipment, development tools, and other technologies. In addition, Oracle is working to establish itself as a leading provider of cloud computing, after being slow to adopt the cloud. But Oracle Database remains the most common technology associated with the company. It is also the leading data management platform for Oracle applications and the data warehouse, BI and analytics systems offered to customers by Oracle.
