Nulls Make Things Easier?

Nulls are a very useful but also very error-prone relational database feature. This talk is designed to help applications developers better manage their use of Nulls.

It covers the use of NULLs in relational databases, with a focus on Postgres behaviour. It covers three-value logic, comparing nulls, mapping nulls to strings, indexing nulls, and aggregates.
