(Yicai Global) Nov. 14 -- Oracle Corp. [NYSE:ORCL], the world's second-largest software company, has slowed its acquisition pace after acquiring 15 cloud-computing companies in recent years, said Philippe Mathieu, the firm's senior vice-president for strategy and operations.

The company will use its existing resources in research and development and internal gained through the takeovers.

Oracle has acquired several types of cloud-related companies over the past six years, such as cloud-service providers, domain-name server providers and cloud-network technology providers.

Oracle's acquisitions of cloud computing companies are based on its transition to the cloud-computing business, enabling it to seize market share quickly when introducing cloud-related products. Mathieu revealed that the company has spent USD100 billion in R&D and M&A during this shift in business.

Mathieu said that Oracle has now been transforming its business for 10 to 15 years, during which it underwent three stages, namely, business transformation, size expansion and digital innovations.

The current stage, digital innovations, involves the digital upgrade of business, systems and process to become standardized and automated as soon as possible.
