Claim Text:
1. A method for matching format defining data structures with at least one data-containing structure, of a group of potentially corresponding data-containing structures, the method comprising: I) analyzing, using at least one processor, attributes of at least some of multiple data-containing structures to identify a set of potential candidate format defining data structures for potentially corresponding to the data-containing structures, wherein the multiple data-containing structures comprise at least one of Virtual Storage Access Method (VSAM) data structures or sequential data sets, non-transiently stored within non-volatile storage, wherein the multiple format defining data structures comprise one or more COBOL copybooks or PL/1 include files, non-transiently stored within the non-volatile storage, and wherein the one or more COBOL copybooks or PL/1 include files have no specifically identifiable data structure defining formats that specifically define data structures within any the multiple data-containing structures to allow for properly accessing data contained within the multiple data-containing structures; II) analyzing, using the at least one processor, at least some of the multiple format defining data structures using record level metrics, the record level metrics comprising record level consistency values, record uninitialized data values and record match values; III) identifying, using the at least one processor, a set of candidate data-containing structures containing data elements having formats substantially corresponding to at least one of the format defining data structures and using file level metrics, based upon results of the record level metrics; IV) ranking, using the at least one processor, the set identified based upon correspondence between one or more of: to obtain a subset of candidate data-containing structures that may correspond to at least one of the format defining data structures; and V) identifying, using the at least one processor, at least one of the format defining data structures that are usable to access at least one of the data-containing structures and thereby obtain valid data from the at least one of the data-containing structures.
