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. [...]

Project Objective and Research Scope
This project aims to design and implement a robust database system for an auto parts warehouse, facilitating efficient inventory management and order processing for an e-commerce platform. The core objective is to ensure data integrity and streamline operations such as customer order management, price querying, and stock monitoring while adhering to strict business logic and constraint rules.
- Designing a normalized database schema including Entity-Relationship modeling.
- Implementing business rules using SQL triggers and stored procedures to ensure transaction reliability.
- Developing query structures to support sales analysis and staff management.
- Establishing a disaster recovery strategy with backup and restore protocols.
- Defining user roles and access control for system security.
