A component based software architecture and data stream processing engine for implementing data mining applications. DBSA is suitable for implenting applications ranging for example from small mobile appications to larger scale and more complex production line applications. The core engine is implemented in C++, but the components the engine is running can be at the moment implemented using Python, Matlab or the R languages (in addition to C/C++). DBSA has built-in support for storing the results of each component in SQL (tested so far with MySQL) tables.
