A family of Microsoft relational database management systems designed for ease of use.

Project for the web is so new that it has the most basic functionality in place. Consider it Project for the web, version 1.0. I know that Microsoft has ambitious plans to expand the functionality of this tool in both the near-term and long-term future. In Microsoft Project, you could create a temporary master project with all of your projects inserted as subprojects, and see all of your tasks in a single location. However, Project for the web does not have this capability. The net result is that you can see one project at a time. Hope this helps.
