Abstract

See full text

A method for matching format defining data structures with data-containing structures involves analyzing attributes of data-containing structures; analyzing format defining data structures using record level metrics comprising record level consistency values, record uninitialized data values and record match values; identifying a set of data-containing structures containing data elements having formats substantially corresponding to a format defining data structure and using file level metrics, based upon results of the record level metrics; ranking the set based upon correspondence between one or more of: a) data types within the set and data types within the format defining data structures, or b) values within the set and definitions within the format defining data structures, to obtain a subset that may correspond to at least one of the format defining data structures; and identifying a format defining data structure usable to access a data-containing structure and thereby obtain valid data therefrom.
