Countries covered in IDC's Asia/Pacific Semiannual Enterprise Applications Tracker include Australia, New Zealand, South Korea, India, China, Taiwan, Hong Kong, Singapore, Malaysia, and Thailand.

The study shows that acquisitions were rampant in the EA space with few major vendors wanting to add technology and delivery capabilities to their existing portfolio.

Few of these acquisitions have already given returns, says IDC that has identified SAP, Oracle, UFIDA, Infor, and Microsoft as the top five vendors in the EA market.

Vendors like Salesforce.com, Bokesoft, and JDA Software have a strong position in secondary market areas like customer relationship management (CRM) market and product supply chain (PSC) market.

The CRM market saw a minor increase in percentage share in 2011 and stood at 23.3 percent as compared to 22.7 percent in 2010, at the secondary market level.
