Development of the enterprise social solutions, which merge social computing and well known enterprise csolutions is a fairly new development discipline, which gains ever more on importance and traction. It is empirically proven that the traditional data processing gets more efficient and productive with an enterprise social layer on top. Although we have large software companies leading the way with integrating social layers in their known solutions – e.g. Microsoft Dynamics CRM with Yammer – there is still a lot of need for integration of the enterprise social solutions with the different software applications in companies. This development session will show how Microsoft’s enterprise social products (SharePoint 2013 and Yammer) – can be integrated with another solutions. It will show how to use these products as a common social layer across the software infrastructure in companies. Session will explore which development possibilities we have, which APIs can we use, how to implement the authentication. It will also show, how to bring such integrated enterprise social layer to the mobile devices. Last but not least, it will show which of the both products can and should be used in which scenario, what are strengths of the both products, and where there can be feature overlapping. Adis Jugo
