Maintenance and Support - Binary Flat Files

The most compact form of data representation is the 'binary flat file', a storage format used on early MS-DOS applications.  These would have been used in business applications written in QuickBasic, Microsoft PDS 7.x, Pascal, or C++.  Common characteristics include a 'header' record with a counter indicating the number of data records, fixed length records, intermixtures of fixed length strings, binary 16-bit and 32-bit integers, and single and double precision MBF floating point.  Our Extraction Analyzer program is used for making visual 'dumps' of these files.  Once a reasonable understanding of the data structure is developed, the program can export the extracted data to SQL based relational databases, whether SQL Server, Oracle, MySQL, or PostGreSQL.
