Eight Companies Owned by Oracle

The acquisition of Aconex, a construction software developer, by Oracle Corporation (NYSE: ORCL) during the winter of 2017 was just another example of Oracle’s reach in the technology market. Acquisitions like this have helped develop Oracle in a multitude of ways, including application development, industry solutions, middleware, server expansion, storage capabilities and network development. While the Aconex acquisition was valued at $1.2 billion, this does not represent Oracle’s most expensive purchase, that would be when Oracle bought PeopleSoft for $10.3 billion in 2005. They are often compared to Google.

On May 7, 2018, the company announced a series of autonomous services products, including Autonomous Analytics Cloud, which combines AI, machine learning and service automation to process information more efficiently. 

Due to the numerous products, services and industries Oracle caters to, it is no surprise that there are a substantial number of important subsidiaries and integrated companies that result in Oracle having the second-highest gross revenue across all software companies.
