QuickFix Autо Service is а service stаtiоn thаt prоvides automotive services and parts to its customers. You have been hired to design a conceptual ERD to track their business operations. Here are some notes based on interviews conducted with the Manager. While the manager has provided most details, make sure your design can support all of QuickFix's stated business needs – you may need to include attributes not explicitly mentioned. Customers: QuickFix serves two types of customers: Individual Customers and Business Customers. Individual Customers have a customer ID, first name, last name, phone number, and email address. Business Customers have a customer ID, business name, phone number, email address, and a contact person's name. Vehicles: Each customer owns one or more vehicles. Each vehicle is owned by exactly one customer. Vehicles are described by their license plate number, make, model, year, and color. Products: QuickFix offers two types of products: Services and Parts. Services are labor-based offerings like oil changes, tire rotations, and brake inspections. Each service has a service code, description, and standard labor charge. Parts are physical inventory items like oil filters, tires, and brake pads. Each part has a part number, description, unit price, and quantity in stock. Service Packages: Some services are actually packages that bundle multiple other services together. For example, a "Complete Fluid Service" package includes transmission fluid flush, brake fluid flush, and coolant flush as component services. A service can be included in multiple packages, and a package can contain multiple component services. Not all services are part of packages – many are standalone services. (Note: A service is either a basic service OR a package, not both.) Mechanics: QuickFix employs mechanics who perform the work on vehicles. Each mechanic has a mechanic ID, name, hire date, and certification level (A, B, or Master). Multiple mechanics may work on a single service visit, and a mechanic works on many service visits over time. Service Visits: When a customer brings their vehicle in for work, QuickFix creates a Service Visit record. Each visit is identified by a visit number and includes the visit date and the vehicle being serviced. During a service visit: Multiple mechanics may work on the vehicle Multiple services may be performed Multiple parts may be used QuickFix wants to be able to use the system to manage their operations effectively. For instance, they want to send out promotional offers when vehicles are likely to be due for major service milestones (e.g. 30,000 mile, 100,000 miles etc.). They want to track which vehicle manufacturers (makes) each mechanic specializes in, enabling them to assign jobs to mechanics with the most relevant expertise. QuickFix also wants to schedule appointments efficiently by knowing approximately how long each service typically takes to complete. Requirements: Create a complete conceptual ERD in text format described in the ERD Text Representation Guide. Requirements: Identify all ENTITIES and their attributes (mark primary keys with (PK)) Identify all SUPERTYPE/SUBTYPE structures (if applicable) Specify all RELATIONSHIPS with cardinalities using (min,max):(min,max) notationMake sure you include justifications for the cardinalities. State your KEY ASSUMPTIONS about the business rules You do NOT need to create associative entities for M:N relationships.
