We plan to construct a database for the FAU parking service system. The FAU has many parking-lots which can accommodate many vehicles. Each parking-lot has id, name, and locattion. A parking-lot consists of many parking spaces (or spots) and each parking space (or spots) has a unique number. Every customer has zno and name. A customer can purchase more than one parking-permit. A vehicle has id, brand, and color. A customer can own multiple vehicies. Each parking permit has no. and price. A parking-permit allows a vechicle to park in dedicated parking spaces (or spots). The FAU maintains a time table and uses it to record when a customer parks a vechicle at a dedicated parking space (or spot) at a specific time-slot in the time- table. A time-table has id, date, and hour. Draw an ER diagram for this application. Specify key attributes of each entity type and structural constraints on each relationship type. Note any unspecified requirements, and make appropriate assumptions to make the specification complete.
