Abstract: This disclosure generally relates to a method and system for requesting a ride for a third party rider. In one embodiment, a user device may be used to transmit a ride request to a server for a third party rider. The user device may receive an indication of a driver from a set of trusted drivers among a pool of drivers. Further, the user device and a device associated with the third party user may receive a ride confirmation.

Abstract: This disclosure generally relates to a method and system for providing a ride for a third party rider at the request of a user ride requestor. In one embodiment, a driver device may be used to receive a ride request from one or more server computing devices for a third party rider. The driver device may receive information identifying the third party rider, including a password. Further, the driver device may transmit real time ride status information to the ride requestor directly or indirectly via the one or more server computing devices.

Abstract: A data lineage system is provided that traces a data lineage of a data warehouse. The data lineage system maps a target data element to one or more source data elements. The data lineage system further stores one or more source surrogate keys within one or more auxiliary columns of a target data record. The data lineage system further stores, for each source data element, a data lineage mapping system record within a data lineage mapping system table that represents the mapping of the target data element and the corresponding source data element. The data lineage system further maps a source data element to one or more target data elements. The system further stores, for each target data element, a shadow system record within a shadow system table that represents the mapping of the source data element and the corresponding target data element.
