ABSTRACT:
Searching is an important problem that arises in a variety of applications, particularly for computerized databases. Further, many such applications involve searching set of (possible very large) integers (e.g., credit card numbers, employee identifiers, customer identifiers, dates, parts numbers, etc.). We present techniques for integer searching in a computer database based on a improved form of hashing which we shall refer to as “size-dependent hashing.” This technique can be used to strike a balance between the available memory in the computer system and the required search time.
