An experimental relational DBMS developed by students @ Faculty of Organization and Informatics, University of Zagreb
What is AKDB?
AK (Russian: Автомат Калашникова, English: Avtomat Kalasnikova) DB is a simple relational database management system developed by professor Markus Schatten of Faculty of Organization and Informatics in Varaždin, Croatia. It is also regularly developed, maintained and fixed by graduate students attending 'Physical Database Modeling' course every spring.
The development started in 2009 and is still ongoing, as building a custom DBMS is not an easy task. Most of it is written in C, with some Python for Server stuff and documentation which is generated automatically and can be viewed in HTML or LaTeX form. More on that in Installation and Build pages.
