Question

Now lets consider designing a database for the a car lot. Consider the following statements ->

Our car lot sells many cars every month (we have a big inventory)
Our car lot has many customers (everyone loves us!)
Our car lot has many sales persons (we are ready to help our customers)
Each car sale persons sells many cars a week (our prices are great)
Our car lot provides many mechanical services (all our mechanics are experts)
Our Service department has many mechanics (any mechanic would love to work here)
Our mechanics provide service to our customers (our repeat business is awesome)

Examine the above information and determine the Entities.
With each entity - determine some attributes for each entity. As a note - is there any information in the above statements that is not helpful for our database design?
Now lets consider our Car Lot database design and determine the relationship of our Entities

Using LucidChart or similar tool (Visio) to construct an ERD based on the above scenario.

The approach to take to solve this problem would likely be accomplished using the following steps in your preferred ER diagraming tool

Read the statements and list out the Entities
Determine some attributes that each entity would have
Determine the Data Types for each of the Attributes
Determine and resolve the Relationship cardinality for the Entities. (Hint - there are multiple Many-to-Many relationships above. Please remember that creating an additional table to resolve is needed) You do not need to include the Data Types.

Follow-up Question

I was told what was missing from my submission was "apparent relationships (i.e PK, FK), correct cardinalities are a must. You have lines from one table to the next, but you did not align the relationship properly."

Please advise on how I would indicate that in my ERD attached.
