Crit-bit Trees: the best way to store sets
A crit-bit tree can be used as a high-speed associative array. For example, an array mapping 54 to 1, 19 to 2, 99 to 3, 85 to 4, and 88 to 5 can be stored as a crit-bit tree containing 54=1, 19=2, 99=3, 85=4, and 88=5. The smallest string in the crit-bit tree larger than 85= is 85=4.

ORM is an anti-pattern
ORM looks great early in a project but breaks down as complexity grows, forcing you to learn SQL anyway. Relations aren't objects. Either use NoSQL for object-like data or write a model layer with real SQL. ORM's abstraction is leaky, its efficiency poor, and the alternatives are better.
