Database Design Using Entity-Relationship Diagrams clarifies ER diagram design by defining it in terms of requirements (end user requests) and specifications (designer feedback to that request). The book emphasizes how communication between designers and users during design is crucial for the elicitation of targeted data, and for the creation of an understandable ER diagram. The authors describe how to develop an ER diagram, how to map it to a database, and how the resulting database can be tested. This definitive guide is a beneficial component of any database course and is a strong supplement for any database professional unfamiliar with ER design.

Database Design Using Entity-Relationship Diagrams, Second Edition.pdf
08-19
Data modeling and database design have undergone significant evolution in recent years. Today, the relational data model and the relational database system dominate business applications. The relational model has allowed the database designer to focus on the logical and physical characteristics of a database separately. In this book, we concentrate on techniques for database design with a very strong bias for relational database systems, using the ER (entity relationship) approach for conceptual modeling (solely a logical implementation).

将以下文字在不改变原意的情况下适当缩写，并翻译：With the deep integration of mobile internet and the catering industry, WeChat ordering mini-programs have become an important tool for the digital transformation of catering enterprises. This article designs and implements a convenient ordering system based on the WeChat Mini Program ecosystem.Starting from the industry background, this article analyzes the research status of domestic ordering systems and clarifies the research goals and content. The system backend is built using the SpringBoot framework and MySQL database, while the front-end interaction interface is developed using the native WeChat Mini Program framework. The development environment uses JDK8, IDEA development tools, and WeChat Cloud Development Platform to ensure development efficiency and system compatibility.The system design section elaborates on the interaction logic and interface layout of the mini-program’s home page, along with the dual-platform architecture for both user and management interfaces. It implements efficient data model management through Entity-Relationship (E-R) diagrams and optimized database table structures. Core functionalities including user authentication and payment gateway integration are developed using modular programming approaches to ensure system security. Comprehensive functional testing procedures validate the system’s stability and operational reliability.
