Partial match then return value from a different cell

Hello, I'm sure this is really easy, but I'm not having any luck with figuring out the correct formula to get the desired results.

I'm trying to compare two lists in separate sheets. If there is a partial match in 'Main' Column A (from 'Database' column D), then return a value in a different column on the main sheet. I've tried using VLOOKUP and INDEX, but can't figure out the right way in order to get it to work.

I've attached a very simple sample file. The first 2 worksheets (Main & Database) are samples of what I currently have. The third worksheet (Desired Result) is how I would like the first worksheet to look once I get the correct formula in column C/D/E on the Main spreadsheet.
