A growing interest in big data, analytics, and cloud computing helped propel a weak software enterprise market last year, according to research from IDC. SAP and Oracle fared the best among the large software vendors. The worldwide software market grew 3.6 percent year-on-year and totalled $342.6 billion, which is less than half the growth rates seen in 2010 and 2011, according to IDC's latest Worldwide Semiannual Software Tracker.
