There are two resources you should review.
1. The Database Reference Document provides information about the tables and fields that comprise the database schema for a project.
2. If you have permission, logon to the project and then access Tools > Customize > Project Entities. Find the entity in question ( i.e. Test) then expand the list of System Fields and User Defined Fields. This will show you the name of the field as it appears in the UI and also the name of the database field that contains the data.
