puredb

Set of libraries for creating and reading constant databases

PureDB is a portable and tiny set of libraries for creating and reading constant databases. It manages data files that contains text or binary key/data pairs of arbitrary sizes. Lookups are very fast (normally only one disk access to match a hash value), overhead is low (a database is 1028 bytes plus only 16 extra bytes per record), multiple concurrent read access are supported, and databases can be up to 4 Gb long, and they are portable across architectures.
