Mapping is one of the areas that has got the biggest attention in BizTalk Server 2010 in terms of user interface. In BizTalk Server 2013, it was improved behind the scenes where the runtime was updated to use XslCompiledTransform, which increases the performance of Map execution.

Maps range from simple to very complex, where the user interface changes have really improved the usability around complex maps.
Simple maps may only include connecting a few elements together using simple direct links as shown in the following screenshot.
