What is it all about?
BayesDB is a probabilistic programming platform that enables users to query the probable implications of their data as directly as SQL databases enable them to query the data itself.

* The Bayesian Query Lanuage (BQL) allows analysts and domain experts to interact perform Bayesian data analysis without requiring a detailed understanding of model implementation. That means queries can be articulated before models have been build, and models can be improved and optimized without invalidating existing queries. * The Meta-modeling Language (MML) enables machine assisted modeling for populations based on samples and domain insight. By specifying population schemas and also by using the MML, domain experts can encode qualitative prior knowledge and control the behavior of BayesDB's built-in model building engine. * MML includes constructs for integrating arbitrary algorithmic models contained in external software, and for invoking a standard library of custom statistical modeling techniques. * BQL enables users to generate answers to a broad class of "what-if?" scenarios, contingencies and hypotheticals. These samples can be used as proxy data in sensitive settings, as the basis for model checking by domain experts, and as the basis for making complex risk-reward tradeoffs requiring full probability distributions on outcomes.
