Global software major Oracle on Thursday said its Indian investment has crossed three billion dollars over the past five years, which reflects the local market as a priority for the company.

The investments include Oracle's approximately two billion dollar acquisition of Mumbai-based banking software company i-flex Solutions two years ago. Oracle holds about 83 per cent in i-flex, which is listed on the Indian bourses.

The enterprise software major has seven development and solution centres in India. On Thursay, it opened two centres -- Asia R&D unit and Partner Solutions Centre -- in Gurgaon to focus on Indian market.

"Our investment in India has crossed three billion dollars over the past five years, which includes the equity in Indian company," company's Chief Technology Officer (Asia pacific and Japan) Kevin Walsh said in New Delhi.

Oracle, which treats India as one of its fastest growing markets, said the new centres that will have handful of people to start with will drive innovation and productivity enhancing IT solutions for the Indian market.

Oracle has over 450 partners in India. The two centres will be part of the 19 R&D and solution units spread across Asia Pacific. The company did not disclose the head count nor did they reveal the investments in these two centres.
