We introduce a free, open-source, non-relational database architecture that is robust, mature, scalable and extensible. The absence of a fixed schema is particularly important to research in the learning sciences where a broad spectrum of research data may need to be stored. We highlight an alternative query mechanism that is suited to highly interactive applications.
