Graph Constraints, and Why You Care.

Date: Dec. 7, 2010
Time: 09:30 - 10:15
Room: Glasgow

Historically, there has been a mismatch--some might even say antipathy--between relational databases and graphs, of which trees are the most common example. Until Common Table Expressions came along, there was really no general way to express trees in a relational database, let alone constrain them. In this talk, you'll learn about expressing trees and more importantly, using PostgreSQL's advanced features in a simple, intuitive way to make constraints like, "This table must contain only trees."
