Business Intelligence is a growing trend in the IT industry, and Microsoft is trying to become a leader in this pioneering industry. In July, the company announced the launch of Power BI for Office 365 subscribers. The service was made to provide businesses with a cloud-based solution to view Office 365 reports, particularly from Excel documents, on the web and via mobile devices. This week, Microsoft quietly launched the Power BI app for Windows 8 and Windows RT as its latest in-house developed app for those operating systems.
