Introduction to Active Record - Silicon Valley Ruby Conference 2007
Active Record is an object-relational mapping (ORM) pattern that allows developers to interact with a database using objects rather than SQL queries. It establishes a direct association between classes and database tables, and between class objects and table rows.
