The EA.Gen.Hub.Addin is a client side install alongside Sparx Enterprise Architect that forwards events to the Service via WCF message channels. The installer registers the COM component with Sparx, and includes a sample config file for internet connection to the server.

By default, the server will record systems parameters to allow a client to connect via TCP without client side confirguration

The Hub uses the tried and trusted EA.Gen.Model Entity Framework library for data access to Sql/Server, Oracle and native eap files (though not recomended).
