I've read the docs for DBMS use with vector themes/layers and am left with more questions than answers.
Because my projects will involve only me I'll use SQLite. 1) My initial impression is that I need a separate database for each layer (i.e., one for highways, a separate one for streams & rivers, etc.). Is this correct? 2) Do I manually create the databases and specify table schema within each location's dbf/ directory? 3) If I want to write SELECT statments that JOIN tables in different layers, then I need to open one database and attach the others. Is this done within GRASS? I'm sure that I'll have more questions as I learn how to use SQLite with vector attributes. The soils data in particular, has a couple of dozen tables associated with it.
