I'm assuming you want to combine like time logs by the Resource/Person Or the Project.
If thats the case, you'll want to create a Resource (or Projects) table and have that be the parent of both child tables. Then you can create the summarized logs for each of the categories.
Depending on how your project data is set up, you could even make all these relationships automatic, which would be nice.
