Vikki is correct about the microfiche. Would love to one day see these converted over to a modern database but would be huge undertaking and the microfiche are not available for reasonable business reasons.
The registry is not a valid sample as it depends on people to enter data, enter it correctly, and then for me to properly code the data retrieval. The last I need to work on while maintaining confidentiality of identifiable information (ie VIN). If I only had more time in the week as I have been promising it for awhile now.
