DAX.do is an online service to play with DAX using just a web browser. DAX.do is mainly a learning tool, but it is also a way to share DAX code and quickly test a DAX expression with a standard sample model (Contoso). If you have any questions about DAX.do, or want to know more about why it exists and the architecture behind it, join this live session with Marco Russo, one of the DAX.do authors. In preparation for the live event, you can also watch the DAX.do – Behind the scenes video at the link below!
