File Processing and Quality Control

Title: International mortality data base [electronic resource]

Original diskette files: All diskettes were mounted on a 3 1/2" drive of a Windows 98 PC. To preserve the original file content, all files were transferred to a UNIX server in binary format and retain their original time and date stamps.

Compressed files: The DOS compressed files were extracted using the file compression software included on the original diskettes (DOS PKUNZIP.EXE) on a Windows 98 PC following the instructions in the documentation file. The decompressed DOS Lotus 123 spreadsheets were transferred to a UNIX server in binary format and retain their original time and date stamps.

Documentation file: The documentation file was obtained from the National Center for Health Statistics. This file is in PDF format.

Processed spreadsheet tables: The original DOS Lotus 123 spreadsheets were translated to ASCII CSV format with Windows DBMS/COPY version 7 (www.conceptual.com). DBMS/COPY translation logs were checked for data translation error messages. No comparisons were made on the actual translated data cell values. The ASCII data files were printed to PDF format with Adobe Acrobat version 5.
