In one embodiment, a device stores, in a database, relationship metadata indicative of an entry in one data field in the database being derived from that of another data field in the database. The device receives a structured database query that includes an identifier for a particular data field and a lineage keyword that requests a data lineage of the particular data field. The device executes the structured database query on the database to generate a data lineage report for the particular data field by tracing the relationship metadata associated with the particular data field to one or more related data fields. The device provides the data lineage report for display. The data lineage report includes information regarding the one or more related data fields.

In one embodiment, characteristics of a connection traversing a packet switching device is determined, which includes, but not limited to, determining a network port number and/or address of an established connection based on a signature of the connection. In one embodiment, a packet switching device receives and forwards packets of particular communication between a device and a remote node in a network. The packet switching device maintains information of the particular communication and identification data for use in subsequent identification of said particular communication. In response to receiving a communications information request specifying a signature related to said particular communications, the packet switching device prepares and sends a response, which typically includes matching the signature to said maintained identification data resulting in identification of said information including a characterization of said particular communications, and sending a reply including the characterization of said particular communications.
