Here is the context for your assignment:

Tim is very impressed with your progress. Good job! You now need to move from analysis to design. Your first design objective is to create a conceptual data model based on Tim$$s business model. Your conceptual data model needs to align with the following guidelines:

Your conceptual model needs to include all the correct relationships between the entities $($i$.$e$.,$ one to many, many to many$).$

You need to include all the correct entities, but you don$$t need to include the attributes for each entity.

Your model needs to use Crow's Foot Notation.Down Town Car Repair Business Case Chegg I am looking for help can you help me create a ERD Digram or Entity Relatioship Diagram with correct relations between entities. I will include screen captures of the Tims business model explanation. Just need all entities and relationships with arrows showing one to one and one to many. the work Tim has done.

Tim will not charge over the bid amount unless he calls

the customer and gets their approval.

If the total amount due is less than a certain dollar amount, the customer has to

pay when they pick up their vehicle. If the amount due is over a certain amount

Tim allows for monthly payments. However, each payment needs to be $10\%$ of

the outstanding amount due or a minimum of $100$ dollars.

If a customer fails to make a payment for one month, he charges a $10\%$ late fee.

If the customer fails to make a payment for a second month, he turns the account

over to a collection agency. The collection agency then tries to collect payment.

If the collection agency fails to collect payment after three months, Tim doesn't

have to pay the collection agency. If the collection agents collects partial

payment or full payment, the collection agency takes $30\%$ of the amount

collected.

Introduction

Tim Smith owns a small car repair shop called Down Town Car Repair. Tim does

small and large car repair jobs for individual customers only. Tim doesn't do

commercial work. Tim manages all his accounts using pen and paper. Tim has

contracted you to automate his small business.

Assignment

You will incrementally build your proposal. Each week you will deliver a small

part of the overall proposal and deliver the final proposal the last week of class.

Business Case

Customers will call or drop in and ask Tim to bid on a repair. If the repair is small,

such as an oil change, Tim will give them a fixed bid. However, if the repair is

complex and needs some time for Tim to investigate the problem, he charges a

fixed amount for the initial investigation and then provides a bid on the work.

Either way, Tim creates a bid for all his work. Customers can either accept the bid

or reject the bid. If the customer accepts the bid, then Tim starts the work.

The bid contains the start date, estimated end date, estimated materials,

estimated labor cost, and total estimated cost of the repairs.

Tim buys material and supplies from various suppliers. Tim has an inventory of

common material, such as belts, oil, tiers, and so forth. However, when a job

requires special material, such as engines or transmissions, Tim orders these

special materials from various suppliers.

All of Tim's suppliers allow him to make monthly payments on the materials he

purchases. It is important that Tim understands what material he is purchasing

for each supplier, the total amount due to each supplier, and the monthly amount

due to each supplier.

Once Tim completes the work, Tim create a bill for the work done. The bill

contains the same information as the bid, but the amounts are adjusted based on
