The use of hints in database management systems, such as Oracle, is another important aspect of finance and cryptocurrency. For instance, the CARDINALITY(table n) hint instructs Oracle to use a specific table, rather than relying on its own statistics, which can be particularly useful when working with global temporary tables.
