In previous sections I discussed design principles, engineering trade offs, and implementation issues of the SQLite engine, and presented some simple SQLite applications. Due to brevity of space, I did not discuss the SQLite frontend parsing system. I encourage you to visit the SQLite homepage at http://www.sqlite.org and follow the links there to get more information about the technology. You can also subscribe to the SQLite mailing list by sending an email to email@example.com. The SQLite source code is well commented and an excellent source of information on SQLite internals. You can learn more about SQLite by actively using the technology.
