When should you avoid creating an index, considering table size?

Answer
Avoid indexes on small tables as they offer little performance gain.
Small tables can be scanned quickly; thus, the overhead of maintaining an index may not be justified. In an e-commerce system, indexing a small 'payment_methods' table might not improve lookup speeds significantly, as the entire table can be swiftly scanned.
