2. Create an ER Diagram for the following scenario (20 Points) A company hosts running races and needs a website built. Runners need to have their information including email address, runnerid, first name, last name, and password. They are unique by email address. Runners are also unique by runner id. Runners also have attributes for how many races they've been in, as well as their best time. Both of these can be computed. An event has a name, an eventid, a date the event, and an address. Events are unique by the eventid. It is also unique by the name. Events also have a charity Events also have multiple sponsors. Each event can have one or more races. A race is only for a particular event, a race must be associated with an event, and an event must have at least one race. For instance, a May the 4th event may have a 5k run and a 10k run. A race has a distance, a unit (in what units the distance is, normally miles or km), a raceid, and the time the race begins. Races are unique by the raceid. A runner can sign up for many races, and a race can have multiple runners signed up for it. A runner technically does not have to be signed up for any races, and conversely the races do not have to have any runners signed up. A runner has a time recorded for the race they are in
