A data stream management system (DSMS) is similar to a database system with the difference that a DSMS can search data directly in on-line streams as well as querying stored data, while a DBMS can search only stored data. Stream queries are called continuous queries because they run all the time until they are terminated. SCSQ is an extensible DSMS allowing different kinds of data sources to be integrated and queried. A SCSQ interface to a data stream system is called a datastream wrapper. A datastream wrapper allows continuous queries to be specified over an external datastream producing system. The Controller Area Network bus (CAN bus), is astandard for interfacing data streams from different kinds of equipment and engines,such as wheel loaders and other vehicles. The objective of the project is to developan interface, called a CAN bus data stream wrapper, to enable SCSQ to access to streams of sensor readings from industrial equipment through CAN bus standard interfaces. It enables the SCSQ user to specify continuous queries over equipmentdata streams.
