Library Management System Course Design Overview
Library Management System Course Design
The Library Management System is a widely used IT project aimed at teaching students the principles and techniques of software engineering, particularly in the development of information management systems. The project requires the use of Visual Studio 2003/2005 as the development platform, and SQL Server 2000 as the database. Students will need to master the use of SQL queries, table creation, and data management. The system also utilizes ADO.NET for connecting to the database and managing data exchanges.
Key functions to be implemented include:
User Management: Registration, login, and permission control for administrators and regular users.
Book Information Management: Adding, editing, and deleting book details like ISBN, title, author, and publisher.
Borrow and Return Management: Handling borrowing, renewing, and returning books, as well as tracking their availability status.
Search Features: Searching books by title, author, and category.
Statistical Analysis: Analyzing the borrowing frequency and most popular books.
Error Handling: Managing issues like overdue books and lost items.
Through this project, students will experience all phases of the software development lifecycle such as requirement analysis, system design, coding, testing, and maintenance. Proper documentation, including requirement and design documents, along with version control (e.g., SVN or Git) and unit testing (e.g., NUnit), is also essential.

Inventory Management System for Small Goods
Inventory Management System
The Inventory Management System is a specialized application designed to handle small goods inventory management using the powerful visual development tool PowerBuilder (PB). PB is a well-established, object-oriented programming environment, particularly suitable for developing enterprise-level database applications. This system is built to help users efficiently track and manage inventory, maintaining optimal stock levels and preventing overstock or stockouts.
Core Features:
Inbound Management: When new goods arrive, the system records all relevant details—such as supplier, quantity, and date—accurately adding new items to the inventory.
Outbound Management: When processing sales orders or item transfers, the system automatically reduces inventory levels of the specified goods and generates corresponding outbound documents, facilitating easy tracking.
Inventory Inquiry: Users can view the current inventory status at any time, checking quantities and locations of items to respond to market demand swiftly.
Inventory Alerts: The system triggers an alert when any item falls below the preset threshold, reminding users to restock and prevent shortages.
Stock Counting: Conduct regular stock takes to verify that actual stock matches system records, addressing any discrepancies.
Report Analysis: Provides various reports, such as inbound/outbound statistics and inventory turnover rate analysis, to help managers make data-driven decisions.
Access Control: Permissions are assigned based on employee roles, with each role limited to specific actions, ensuring data security.
System Integration: The Inventory Management System can integrate seamlessly with other business systems (e.g., ERP, CRM), enhancing overall operational efficiency.
User Interface: Applications developed in PB feature intuitive graphical user interfaces, making operations simple and lowering learning curves.
Customization: PB’s flexible development capabilities allow for system customization to meet specific business needs, catering to diverse operational scenarios.
This Inventory Management System offers significant benefits in small goods inventory management, enhancing efficiency and reducing human error. It is an indispensable tool for small goods retailers or wholesalers aiming to optimize inventory strategy, reduce costs, and increase operational efficiency.

Denormalized Design in Database Management
非规范化设计
规范化的最终产物是一系列相关的表,这些表构成了数据库。但有时候,为了得到简单的输出,你得连接多个表,这影响了查询的性能。在这种情况下,更明智的做法是引入一定程度的冗余,包括引入额外的列或额外的表。为了提高性能,在表中故意引入冗余的做法称为非规范化。
考虑非规范化的情况
大量频繁的查询过程涉及的表都需要进行连接。
主要的应用程序在执行时要将表连接起来进行查询。
对数据的计算需要临时表或进行复杂的查询。

Library Management System Detailed Design Documentation
Library Management System Detailed Design Documentation utilizes Visual Basic as the front-end application development tool, with Access as the back-end database, running on the Windows 2000 platform. The entire system is built using Microsoft’s operating systems and development tools, ensuring consistency, integrity, and ease of use for the application. As a typical information management system, the goal is to enhance the efficiency of managing and circulating library resources through computer technology.
System Components:
User Management Module:
Provides functionalities like user login, password modification, and security features. For instance, the system exits automatically after three failed login attempts.
Algorithm descriptions are created using PAD diagrams to ensure secure user authentication.
Library Business Data Flow:
Analyzes the data flow through Data Flow Diagrams to clarify input, processing, storage, and output, ensuring information flow logic.
Functional Module Design:
Includes core subsystems such as book borrowing, user management, and book information maintenance. Each module has distinct functions and relationships, such as loan rules, maintenance, and report generation.
Access Control:
Implements high-level access control with database security authentication, enabling user creation and permission distribution.
Custom access levels for different users like students and teachers, e.g., teachers can access restricted information views, ensuring data privacy.
Through this design, the Library Management System supports library operations effectively, enhances information management, and meets user needs across multiple user types. It is also scalable to accommodate future demands.
