Periodically it becomes necessary to make schema changes to our ftp files. We have made several changes to the Appraisal data files that range from changing field names and sizes to consolidating data from two tables into one table. A report of the changes has been generated and is available at http://www.polkpa.org/ftpreport/ftpreport.html
The report is Interactive HTML. You can expand and collapse the object groups in the Interactive HTML report. By clicking an object you can view the differences in the object creation scripts.
