These views map directly to the tables that comprise the Enterprise Architect repository. They are used to provide a level of indirection between the repository and the (EA)<sup>2</sup> views. You can also use them to temporarily put filtering criteria on them to find certain elements. Just do not forget to remove the filters when you are finished. For each Enterprise Architect table of interest to (EA)<sup>2</sup>, you will find a corresponding view without the 't_' prefix that is Sparx's table naming convention.
