Abstract: 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.

Abstract: In one embodiment, a system comprises a processor to retrieve a first data element including a value X0 and Y0, provide a hash function for use with a hash table having buckets, the hash function having a first and second input that in combination map to one of the buckets wherein the first input is in a range of X-values having X-value sub-ranges, the second input is in a range of Y-values having Y-value sub-ranges, different combinations of the X-value sub-ranges and the Y-value sub-ranges map using the hash function to different buckets, and input the value X0 and Y0 into the hash function yielding an output which is indicative of a first bucket of the hash-table. Related apparatus and methods are also described.
