Question 24

Explanation

A. Develop three tables: Vehicles, Maintenance Records, and Driver Assignments. Vehicles store vehicle data, Maintenance Records track maintenance, and Driver Assignments record driver-vehicle assignments. This proposition is the most suitable for the situation given. By creating three separate tables, the transportation company can effectively organize and manage their vehicle fleet data. The Vehicles table will store all the necessary information about each vehicle, such as make, model, and registration details. The Maintenance Records table will track all maintenance activities, including dates, services performed, and costs. The Driver Assignments table will record driver-vehicle assignments, ensuring that each vehicle is properly assigned to a driver. This high-level structure allows for efficient data storage and retrieval, making it easier for the company to manage their fleet effectively. B. Create a single table for all fleet data, including vehicles, maintenance records, and driver assignments. This proposition is not the most suitable for the situation given. Creating a single table for all fleet data may lead to a cluttered and inefficient data structure. It would be challenging to manage and retrieve specific information related to vehicles, maintenance records, and driver assignments. Additionally, it may result in data redundancy and make it difficult to maintain data integrity. Therefore, this proposition is not the best choice for the transportation company's needs. C. Develop a single table for Vehicles, with fields for maintenance records and driver assignments. This proposition is not the most suitable for the situation given. While it suggests creating a single table for vehicles, it does not address the need to store and manage maintenance records and driver assignments separately. Combining all the data into one table may result in a lack of organization and difficulty in retrieving specific information. It is important to have separate tables for maintenance records and driver assignments to ensure efficient data management. Therefore, this proposition is not the best choice for the transportation company's needs. D. Create three separate databases for fleet data: Vehicles, Maintenance Records, and Driver Assignments. This proposition is not the most suitable for the situation given. Creating three separate databases for fleet data may lead to unnecessary complexity and difficulty in managing and retrieving information. It is more efficient to have a single database with separate tables for vehicles, maintenance records, and driver assignments. This allows for better organization and easier data management. Therefore, this proposition is not the best choice for the transportation company's needs.
