Lookups

The process of searching for and retrieving information from a database, table, or reference source. This involves specifying a search criterion (a 'key') to locate relevant data within a larger dataset. lookups are fundamental in various fields, enabling efficient access to stored information. They range from simple dictionary searches to complex database queries, and may involve indexed structures, hashing algorithms, or other search optimization techniques to improve speed and accuracy. The result of a lookup is typically the data associated with the key or an indicator of the data's absence.
