Database Literacy: Why use a database? (papercraft version)
Information is what we know about something.
Data is raw information that can be manipulated by a computer.
So a Database is a structured collection of information.

Database Literacy: Paper Data Models for One to Many and Many to Many relationships
I designed a pair of paper data models, pamphlets basically, to assist with teaching database concepts. The two paper data models use data about books and authors to demonstrate a flat file database, a one to many database relationship, and a many to many database relationship. These pamphlets are then used by students during class to recreate the same data models in Microsoft Access.
