The database designed for AutoParts Warehouse is to mainly serve as an ecommerce website. Customer can register online with their shipping address and transaction information. Customer can search the parts they need from company website and place order. According to the order come from customer, company can ship the parts to correspondent customers. In order to make economy efficient, company won’t save too many parts in stock. Oppositely, Company will keep only minimum number of each part. If one of parts runs out of stock, a staff will order the part from vendor and then send it to customer. Our scope will mainly cover the function of customer order, price query, parts summary and company stock. Online transaction with bank and shipment with shipping company are out of our scope. [...]

Chapter Summaries

1. Description of the application and its users: This chapter introduces the auto parts warehouse database designed for an e-commerce website. It outlines the user roles (web customers, customer representatives, staff managers, and database administrators) and the core processes, including customer order placement, part queries, inventory updates, and stock management. The scope is defined, focusing on customer orders, price queries, parts summaries, and stock, while excluding online banking and shipping operations. Assumptions such as a complete car list and unchanging vendor prices are stated. The chapter lays the groundwork for the subsequent sections by clearly defining the application's purpose, user interactions, and the boundaries of the database design.

2. Conceptual and physical design of your database: This chapter details the conceptual and physical design of the database, building upon the requirements and processes outlined in Chapter 1. It includes an Entity Relationship Diagram (ERD) and explanations of the relationships between different entities (customers, parts, vendors, etc.). The chapter sets the stage for the more detailed discussions of transactions, integrity rules, and queries in subsequent chapters.

3. Explanation of transactions that impact the database and their SQL implementation: This chapter describes the SQL implementation of various transactions impacting the database. It details the processes involved in modifying the database through SQL commands. This chapter is crucial for understanding the practical implementation of database interactions, complementing the conceptual design introduced in the previous chapter.

4. Documentation of all integrity rules: This chapter documents the database's integrity rules, ensuring data consistency and accuracy. It outlines primary and foreign key constraints, null value restrictions on key fields (customer, staff, part, and vendor names), uniqueness constraints for email addresses, and positive constraints for price and quantity. The chapter also details rules for managing inventory updates, including consistency between the main part table and supporting inventory information, ensuring that updates are made to all relevant tables simultaneously. Further rules ensure data consistency and correctness during stock management. This chapter is essential for understanding how the database design maintains data integrity.

5. Documentation of all queries: This chapter details the various queries used to access and manipulate data within the database. It provides examples of how to retrieve specific information from different tables, allowing users to interact with the data efficiently. This chapter complements Chapter 3, which focuses on transactions, by providing the querying mechanisms needed to retrieve and display this modified information.

6. Documentation of users and their roles: This chapter defines the different user roles within the system (Web Customer, Customer Representative, Staff Manager, and Database Administrator) and their respective permissions and access levels. It provides the specific functionality and capabilities of each role within the database system, ensuring controlled access to specific data and functions.

7. Documentation of test result: This chapter outlines the testing procedures used to verify the database's functionality and data integrity. It describes the results obtained through data integrity and functional testing, validating the correctness and reliability of the database design and implementation. The chapter aims to validate the correctness and reliability of the previously designed and implemented database system.

8. Disaster recovery plan of AutoParts Warehouse: This chapter presents a disaster recovery plan, covering procedures for backing up and restoring the database, and outlines the backup strategies that provide continuous protection for critical database information.

9. Documentation of the data warehouse and its purpose: This chapter describes the data warehouse design, outlining its purpose and functionalities, such as providing inventory statistics, geographic information, and support for data mining scenarios. The chapter aims to explain the design and the overall purpose and functionalities of a comprehensive data warehouse.
