I start with coverage of what NULLs are and how they behave in comparisons. Finally, I cover missing standard features related to NULL handling in T-SQL and suggest alternatives that are available in T-SQL. For the most part, SQL was designed to assume that NULLs represent the Missing But Applicable kind of missing value.
