This is my first project outside of school so I’m rusty and lacking practice.

I want to create a database but I’m not sure if I’m doing ok so far. I need a little help with the reports table.

The situation:

  • The food bank has multiple agencies who hand out food
  • Each agency has to submit a report with how many families/people served from a long list of zip codes.
  • I thought of putting a fk on Report to Zips table. But will that make selecting multiple zips impossible?

Maybe I’m way off base. Does someone have a suggestion for me?

    A better name for this table might be FoodService or something. I imagine the kind of reports you really want to end up are not just a single row in this table, so naming it Report is a bit confusing.

    In any case, each Report is the unique combination of {Agency ID, ZIP code, Date} and of course Agency ID is a foreign key. The other columns in this table would be number of families and people served, as you’ve indicated. This means you’ll have rows for each agency-ZIP-date combination like this:

    Agency   | ZIP   | Date   | FamiliesServed | PeopleServed
Agency A | 12345 | Jan-12 | 100            | 245
Agency A | 12340 | Jan-12 | 20             | 31
Agency B | 12345 | Jan-12 | 80             | 178
Agency B | 12340 | Jan-12 | 0              | 0

    Are these totals also broken down by “program”? If so, program needs to be part of the primary key for this table. Otherwise, program doesn’t belong here.

    Finally, unless you’re going to start storing data about the ZIP codes themselves, you don’t need a table for ZIP codes.
