greetings and question about data stores

[Richard Schilling]

Greetings.  This is my first post to the list.

I would like to know about the code base itself.  There is not any 
documentation that discusses the structure of the code itself and how 
the software interacts with the data store.

Can any one tell me what source code files actually contain the code 
that writes to the data store?

Thanks!
