Summary:Disclosed is a method for querying by pattern matching a relational data store, including a collection of records having a preset number of attributes, wherein the representation of the content of a structured or unstructured data source also encodes the structure of the data source, and including these steps:providing at least one query comprising at least a find- and a where-clause, wherein the where-clause comprises one or more query patterns, and the find-clause specifies a subset of attributes optionally including aliases thereof; executing the query by:applying predicates in the one or more query patterns to identify a subset of matching or non-matching records;forming the intersection of the two or more subsets of records for two or more patterns;in accordance with the find-clause, selecting specified attributes and applying any aliases; andthereby identifying the subset of records satisfying constraints expressed in the query patterns.
