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. There is neither concept of data tables nor data types. Records are organized in hash table, B+ tree, or fixed-length array.</p><p>Tokyo Cabinet is developed as the successor of GDBM and QDBM on the following purposes. They are achieved and Tokyo Cabinet replaces conventional DBM products.</p><ul><li>improves space efficiency : smaller size of database file.</li><li>improves time efficiency : faster processing speed.</li><li>improves parallelism : higher performance in multi-thread environment.</li><li>improves usability : simplified API.</li><li>improves robustness : database file is not corrupted even under catastrophic situation.</li><li>supports 64-bit architecture : enormous memory space and database file are available.</li></ul><p>Tokyo Cabinet is written in the C language, and provided as API of C, Perl, Ruby, Java, and Lua. Tokyo Cabinet is available on platforms which have API conforming to C99 and POSIX.
