Salesforce.com Inc reported better-than-expected quarterly revenue, helped by an increase in demand for its web-based sales and marketing software, and raised its full-year profit and revenue forecast. Businesses are increasingly moving toward cloud software services that cost less and are easier to manage, helping companies such as Salesforce and human resource management software provider Workday Inc. Spending on enterprise resource management and customer relationship management has been particularly strong. Research firm IDC expects ERM and CRM software sales to grow 20 percent at a compounded annual rate every year from 2013 to 2018.
