In SSIS 2012 there are two deployment models One is package Deployment Model and the new one being introduced is project deployment model. In SSIS 2008 we have been working with the package deployment model. In this model once a SSIS project is created, we have a project folder under which we have sub folders like Data Sources, Data Source Views and SSIS packages. In SSIS 2012 when we create a SSIS project it is by default created in the Project Deployment Model. In the Snapshot below we see Project Params, Connection Managers , SSIS packages and Miscellaneous.
