The flat file format was chosen over other file formats because it can be easily defined and easily understood.
Further, it is equally useful whether the user’s computer is a mainframe or a personal computer. The flat file format defined here is kept as simple as possible. No attempt is made to separate header data from line item data. The benefit is that each record in the file completely defines the test data for each transformer on which test data is being reported. Flat files are also referred to as fixed length files in which each line or record (ile) consists of a specific number of characters. Each data element field is located in a predefined position in the string of data element fields, and each data element field contains a predetermined number of characters. For Alphanumeric fields, unused element positions are left blank. In Numeric and Integer fields, the unused elements will be flled with zero (0) so that data field position is maintained in a consistent fashion in each record.
The file definition is ASCII format with each record (line) representing an individual transformer in the case of the standard data set. The record layout is given below for both the standard data set transformer record and the extended data set transformer record. W hen the extended data set record is requested, the data elements of the standard data set listed in Table 1 will be shown on one line, immediately followed on a separate line by the data elements shown in Table 2, and together, the two lines will constitute an extended data set transformer record. Alphanumeric fields are defined as left-justified with unused elements left blank. Integer and Fixed decimal fields are right-justified with the balance of the field filled with zeroes.
Test data element fields could have been defined as either header data or item detail data. Header data applies to all transformers in the report or to a group of transformers. Item data applies to only one transformer in the report. The beneft of excluding header data would have been to eliminate the repetition of data in the file; the cost would have been a loss of simplicity. Therefore, header data is included in each transformer record.
5.2.2 Standard data set transformer record
The record layout for the standard data set is given in Table 1. The field sequence number, field name, field length, and from-to column is given for each data element field in the record. The standard data set transformer record consists of one line.
5.2.3 Extended data set transformer record
The record layout is given Table 2 for the additional data elements that, when included with the standard data set, comprise the extended data set. The field sequence number, field name, field length, and from-to columns is given for each data element field in the record. The extended data set record consists of two lines.IEEE C57.12.37 pdf free download.
