+Create a database for taking notes.
+
+* What are the columns that a note table needs?
+id, title, body, author, timestamp,
+
+* If you have a timestamp field, how do you auto-populate it with the date?
+DATETIME used with GETDATE()
+
+* A note should have a foreign key pointing to an author in an author table.
+
+
+* What columns are needed for the author table?
+id, name, 
+
+Write queries that:
+
+* Insert authors to the author table.
+insert into author (name) values ('Bob');
+insert into author (name) values ('jim');
+insert into author (name) values ('jim bob');
+
+* Insert notes to the note table.
+insert into note (title, author_id, body) values ("Test note1", 1, "This is a test note!");
+insert into note (title, author_id, body) values ("Test note2", 2, "I am your master");

+
+* Delete authors from the author table.
+  > Note that SQLite doesn't enforce foreign key constrains by default. You have
+  > to enable them by running `PRAGMA foreign_keys = ON;` before your queries.
+
+  * What happens when you try to delete an author with an existing note?
+  it keeps incrementing each time you add in a new value. so instead of starting at a new index its always missing that one anytime you pull records. 
+
+  * How can you prevent this?
+  reseed the value
+
+Submit a file `notes.sql` with the queries that build (`CREATE TABLE`/`INSERT`)
+and query the database as noted above.
