First encounter with SQL using the Antarctic survey data as an example.

• @tomwright01: 3 hours

• code/gen-survey-database.sql: re-generate survey database used in examples.
• code/sqlitemagic.py: IPython Notebook plugin to handle SQLite databases.
• data/*.csv: CSV versions of data in sample survey database.

• Run sqlite3 survey.db < gen-survey-database.sql to re-create survey database before loading notebooks.
