/**
 * Instances of this exception type are thrown by methods in DAL
 * library which query a primary data source. Primary data sources are
 * data sources that  actually generate the data, such as measurement devices,
 * databases etc. The failure may occur because of the inability to connect to
 * the data source,  to communicate to the data source or to actually exchange
 * the data (for example,  because of incompatible data formats). This
 * exception type acts as a wrapper  for an exception thrown by the layer
 * underlying the implementation of DAL.
