    Need to complete the rest of my assignment that I can&quot;t do - involves SQL and ER DiagramsQ.A group of people are setting up a car pooling arrangement and require a database to manage the information about pickup locations, drivers, passengers and the routes that will be driven. Use the following information to draw an ER diagram for the required database with the symbols and notation used in lectures and notes. You must not submit scanned or bit-mapped diagrams. This will result in reduced marks. A route is identified by a Route ID and has an associated departure time. There are many Pickup locations. Each one has a unique number known as an L number. There is also a description with details of precisely where the pickup is for that location.Each route is made up of many locations. Individual locations can appear on more than one route. People who register to use the service as a passenger are each given a P number and their name and mobile number is recorded. Other people register as drivers. They are each given their own D number and also supply their name and mobile number. Based on their needs, passengers in the system select the pickup location they prefer and record the time they expect to be at the pickup location. Routes are allocated to drivers. There are always more drivers than routes so every route has a driver. Each route starts and
