A data collection system is provided. The system comprises a plurality of data sources that produce data. At least some of the plurality of data sources produce data in different formats. The system also comprises a plurality of listeners stored in a computer readable storage medium that, when executed by a processor, receive the data from the plurality of data sources, identify the data, parse the data, convert the data into a generic format, and validate the converted data. The plurality of listeners are implemented using a script programming language. The system further comprises a loader stored in a computer readable storage medium that, when executed by a processor, loads the converted data into a database. The loader is implemented using an object oriented programming language.
