Kyoto Cabinet is a library of routines for managing a database. The
database is a simple data file containing records, each is a pair of
a key and a value. Every key and value is serial bytes with variable
length. Both binary data and character string can be used as a key
and a value. Each key must be unique within a database. And there is
neither concept of data tables nor data types. Records are organized
in hash table or B+ tree.
