Entity-Relationship Diagram (ERD)

This plumbing and piping plan sample shows the food truck hot and cold water supply system.
"A food truck, mobile kitchen, mobile canteen, roach coach, gut truck, or catering truck is a mobile venue that transports and sells food. Some, including ice cream trucks, sell frozen or prepackaged food; others resemble restaurants on wheels. Some may cater to specific meals, such as the breakfast truck, lunch truck or lunch wagon, snack truck, kebab trailer (UK), break truck, or taco truck.
Food trucks also cater at events (carnivals, construction sites, sporting events etc.) and places of regular work or study – college campuses, office complexes, industrial parks, auto repair shops, movie sets, farmers markets, military bases, etc. – where regular meals or snacks are in high demand by potential customers."
