Oracle Corp, the world's No. 3 software maker, plans to buy privately held GoldenGate Software, beefing up its portfolio of technology that helps companies manipulate information in databases.

The companies did not disclose financial terms of the transaction, which Oracle announced on Thursday.

Oracle has spent more than $34 billion buying about three dozen companies over the past five years, the bulk of then private companies like GoldenGate. While Oracle does not release the terms of most small transactions, Oracle spent up to $1.2 billion for such deals in its most recent fiscal year.

The software giant is getting ready to close its $7.4 billion acquisition of hardware maker Sun Microsystems Inc, pending antitrust approval by regulators in the United States and Europe.

San Francisco-based GoldenGate offers several products, including software that helps businesses analyze large quantities of information in databases and programs that help banks detect fraudulent activities.

GoldenGate has more than 500 customers, including Bank of America Corp, Comcast Corp, MGM Mirage and Visa Inc.

Shares in Redwood City, California-based Oracle rose 2.5 percent to $22.31, in line with a gain in the Nasdaq Composite Index.
