This is a great article on codeplex about creating a tablular model using AMO 2012. I am in the process of designing methods to extract information from the BISM tabular model using AMO and XML. I just wanted to share this with you as I will begin to analyze this method further. I will be posting some code here and there to show the differences from Multidimensional and tabular AMO.
