A data analysis system for analyzing data from multiple devices has a database service module including a data storage subsystem storing data collected from different devices. The data is stored in a meta-structure using primitives to classify the data. An analysis engine analyzes the data to determine whether the data defined by the meta- structure meets certain criteria in accordance with a stored set of rules. The system is useful, for example, in the detection of faults in railway infrastructure. |
