You're miles from being ready to worry about "the same time." Don't
start threading till you can get a simple multi-module program understood.

For some reason you capitalize all those filenames, so you're stuck with
unpythonic module names. If you want your code readable, use lowercase
for module name, and Capitalized for class name.

Nobody's going to be able to understand your code if you persist in
using self in unpythonic ways. It's used as the first argument of a
class method. Period.

So call it:
firstarg = whatever * RequestType
secondarg = something different + RequestValue
result = HomeDatastore.QuerySqlite(firstarg, secondarg)

Where are your import statements? No module automatically sees imports
that were done elsewhere. Import what you need in a module.

I don't see any 'update data' function anywhere, but if you want to call
QuerySqlite, you need to call it:
thisresult = HomeDatastore.QuerySqlite(him, her, theother)

You presumably mean
def QuerySqlite(firstparam, secondparam):
since a function with no arguments is going to be stuck trying to use
globals, and that's not a good habit to get into.
