Answer 1

In regard to your last part of the question, this is not as simple as you want it to be. You have to programmatically limit the amount of rows. Like something with the following pseudocode

if number_of_rows in <table> > limit
    do not insert
    OR
    remove oldest row and insert new
else
    insert row

But why would you ever want to limit the amount of rows in a table?

EDIT:

You can infact remove your database programmatically.
You have to use a reference to the context to remove it with deleteDatabase
