The Very Hungry Transaction
The story begins with a little database transaction. As the days go by, more and more business requirements cause the transaction to grow in size. We soon discover that it isn't a little transaction anymore, and it now poses a serious risk to our application and business. What went wrong, and how can we fix it?
In this talk we'll witness a database transaction gradually grow into a liability. We'll uncover some common but problematic patterns that can put our data integrity and database health at risk, and then offer strategies for fixing and preventing these patterns.

Reflecting on Active Record Associations
Active Record associations seem magical—add a has_many here, a belongs_to there, and suddenly your models are loaded with behavior. Could it be magic, or is it plain old Ruby with some thoughtful design and a bit of metaprogramming? In this talk we'll study Active Record associations by writing our own belongs_to and has_many macros. We'll dynamically define methods, cache query results, replace a a Relation with a CollectionProxy, and automatically prevent N+1 queries with inverses. You'll leave with a deeper understanding of associations, and a new appreciation for their magic.
