Buad 2020 Assignment 4database Creation With Microsoft Access40 P

Create a new database (named yourLastName_AutoRepair.accdb) that tracks customers, their cars, repairs, repair types, and employees at an auto repair shop. The database should include tables for customers, cars, repairs, repair types, and employees, each with appropriate attributes. Establish correct relationships among tables using primary keys (AutoNumber) and foreign keys (Number). Populate each table with sample data: at least 5 customers, 8 cars (some customers with multiple cars), 18 repairs (some vehicles with multiple repairs), 5 repair types, and 4 employees. Use the provided figure as a reference for relationships. Submit the completed database file with correct table structures, data, and relationships.

Sample Paper For Above instruction

Creating an effective database for an auto repair shop involves precise planning and implementation of tables, relationships, and data entry to facilitate efficient management of customer, vehicle, repair, and employee information. This paper demonstrates the process of designing and populating such a database in Microsoft Access, adhering to provided specifications and best practices.

Designing the Database Structure

The foundation of any relational database lies in well-structured tables with clearly defined relationships. For this project, five primary tables are essential: Customers, Cars, Repairs, Repair_Types, and Employees. Each table must include necessary attributes with appropriate data types, utilizing AutoNumber for primary keys and Number for foreign keys to establish relationships.

Table Creation and Attributes

1. Customers Table: This table stores client information, including CustomerID (AutoNumber, Primary Key), FirstName, LastName, Address, City, State, ZIP, and MainPhone. These fields facilitate identifying and contacting customers.

2. Cars Table: It tracks each vehicle, with CarID (AutoNumber, PK), CustomerID (Number, Foreign Key), Make, Model, and Year. The CustomerID links each car to its owner.

3. Repairs Table: This records repair details, including RepairID (AutoNumber, PK), CarID (Number, Foreign Key), RepairTypeID (Number, Foreign Key), HoursWorked, and TotalCost.

4. Repair_Types Table: It standardizes repair categories with RepairTypeID (AutoNumber, PK) and RepairDescription.

5. Employees Table: Contains EmployeeID (AutoNumber, PK), FirstName, LastName, and HireDate.

Establishing Relationships

Proper relationships are vital ensuring data integrity and facilitating meaningful queries. Using the provided figure as a reference, relationships will include:

• Customers to Cars: One-to-Many (one customer can own multiple cars).
• Cars to Repairs: One-to-Many (each car can have multiple repairs).
• Repairs to Repair_Types: Many-to-One (each repair corresponds to a repair type).
• Repairs to Employees: Optional relationship if tracking which employee performed a repair (not specified but advisable).

Data Population

Sample data must be entered to demonstrate functionality:

• At least five customers with realistic addresses and phone numbers.
• Eight cars, with some customers owning two or more vehicles.
• Twenty repairs spread across the cars, with some vehicles undergoing multiple repairs.
• Five repair types (e.g., Tire Rotation, Oil Change, Brake Inspection).
• Four employees involved in repairs, with names and hire dates.

Implementation Tips

- Always define primary keys as AutoNumber to ensure unique identifiers.

- Set foreign key data types to Number, matching primary key types in related tables.

- Use the Relationships tool to link tables based on primary and foreign keys, enforcing referential integrity.

- Populate tables through datasheets or forms, ensuring each attribute is completed with appropriate data.

Submission and Evaluation

The final database should exhibit correct table creation, proper data types, accurate relationships, and sufficiently populated tables to demonstrate the system's functionality. Proper submission entails uploading the completed yourLastName_AutoRepair.accdb file to Blackboard. The grading rubric emphasizes table correctness, attribute appropriateness, relationship accuracy, data population, and proper submission.

Conclusion

Designing this database showcases skills in relational database concepts within Microsoft Access, emphasizing clarity, consistency, and accuracy. Proper implementation supports efficient management and reporting for the auto repair shop, aligning with best practices in database design principles.
