Overview
DBM (Database Manager) is a concept of libraries to store an associative array on a permanent storage. In other words, DBM allows an application program to store key-value pairs in a file and reuse them later. Each of keys and values is a string or a sequence of bytes. The key of each record must be unique within the database and a value is associated to it. You can retrieve a stored record with its key very quickly. Thanks to simple structure of DBM, its performance can be extremely high.
Tkrzw is a C++ library implementing DBM with various algorithms. It features high degrees of performance, concurrency, scalability and durability.
