Write app ops access data into sqlite

App op access data is primarily an audit data and is written
only once, the data is never updated. however, we keep truncating
the old data. The current architecture of discrete & historical
registry is pretty complex and the xml as persistence layer has
caused deeply nested classes. With Sqlite we are trying to
make app ops audit data more debugable, robust and simplifying
the code.
