Nock --
I'm not a DBA professionally, so please understand this is a very simple
explanation of the SQL Server tables in Project server:
The system stores project data in a collection of tables labeled with the
prefix "msp_." The system populates these project tables each time the
project manager saves a Microsoft Project plan in the Project Server
database.
When the project manager publishes a project to Project Web Access, the
system stores the published data in a collection of tables labeled with the
prefix "msp_web."
Each time the system processes the OLAP Cube, it stores the data in a
collection of tables labeled with the prefix "msp_cube."
The system stores data used for the processing of business and presentation
logic in Project Web Access in a collection of tables labeled with the
prefix "msp_view."
Please keep in mind that this is a very simple explanation of the Project
Server database. Since you are a newbie, please refer to the following FAQ
about documentation and training on Project Server 2003:

Hope this helps.
