A computer implemented method and system for interrelating and providing ordered access to source data files (SDFs) is provided. Each SDF contains one or more records. A parsing component compiles a configuration language (CL) and generates file descriptors usable by an interlinear sort component (ISC) and an interrelated data access component (IDAC). The CL defines adopt and order key fields, a lineage relationship between the SDFs, and one or more predetermined subprograms. The subprograms process an instance of a record from a SDF and a start point and an end point of a sequence or a subsequence of related records from the SDF. The ISC sorts each SDF into the order defined in the CL and attaches a parent position number (PPN) to each child file record. The IDAC uses the PPN to access the sorted SDFs in the order defined by the CL and execute the defined subprograms.
