Abstract: A system and method for continuous processing of data streams residing in distributed data sources. The method includes: receiving a plurality of data streams from a plurality of distributed data sources; processing each of the plurality of data streams using a plurality commands, the plurality commands are executed in parallel using a graph execution engine; and transporting, through a transport layer, each of the plurality of data streams using the plurality commands to at least one data sink.

Abstract: A system and method for performing a hash bucketing process on data in motion are presented. The method includes applying a first hash function on an input dataset to map the input dataset to a bucket, wherein the first hash function results with a first hash value; applying a second hash function on the first hash value to map the input dataset to a record in the bucket; generating metadata based on the input dataset, wherein the metadata at least points to the original location of the input dataset; and storing the generated metadata in the record in the bucket.

Abstract: A system and computer implemented method for cataloging database metadata using a signature matching process are provided. The method includes receiving an input name to be matched to a key in a seed table; generating a first fingerprint by decomposing the received input name into a first set n-grams; generating, based on the received input name, a second fingerprint using a predetermined pronunciation schema, wherein the second fingerprint is a phonetic fingerprint; generating a third fingerprint by decomposing the second fingerprint into a second set of n-grams; identifying a matching key by matching any combination of the first fingerprint, the second fingerprint, and the third fingerprint against keys in the seed table; and cataloging the metadata with the matching key as a tag.

Abstract: A method and system for tagging database columns are presented. The method includes receiving an input column name of at least one column in a database; performing signature matching of the input column name to contents of a seed table; determining a first confidence score for the signature matching; and tagging a matching value in the seed table as a tag for the input column name, when a first confidence score exceeds a first threshold value.

Abstract: A system and computer implemented method for cataloging database metadata using a probabilistic signature matching process are provided. The method includes receiving an input name to be matched to keys in a data corpus; dividing the received input name into a plurality of text segments; identifying a set of matching keys by matching each of the plurality text segments against keys in the data corpus; analyzing the set of matching keys to construct a tag; and cataloging the metadata with the matching key as the construct tag.
