From the developer:
""The majority of the programs developed in C++ (as well as other languages) make an extensive use of data. However, there are no 'built-in' features to create easily relational databases. That's why we developed quickdb. quickdb enables you to have access to a light database engine, which is fast and reliable (developed in C++) with object oriented methods. Quickdb is a light database engine which resides in memory and which permits you to have a very versatile database for C++ programs. quickdb is fast and reliable (developed in C++) and does not rely on any other package (it is totally self-contained). It is delivered in a dll, which can be distributed. If you are a C++ developer, you may want to try quickdb.""
