Garden Harvest Submodel Given visual access to the various beds the gardeners, naturally asked for more. They wanted to see what was harvested from any given location so they could plan crop distribution in the future. So they wanted to have the ability to record harvest information in the database directly from a visual display. 
This meant we had to include some harvest related entities and relationships.This seemed straightforward enough until we tried to establish what kind of information was involved. How do you measure a harvest? The answer depends on what is being harvested. Some things you count, others you weigh and still others you measure the volume. Our resolution was to provide a reference for the thing being harvested called 'Harvest Unit'. Harvest Units each have associated measurement methods for either volume or weight categories and with each category there is a choice of units of measure © 2023 Datamorphosis Inc. - P.O.
