Introduction
This book is compiled based on the author's years of Delphi development experience. The book is divided into basic and application. This topic describes Delphi's deep programming technology in combination with examples, including Chapter 9: understand Windows messages, processes and threads, writing custom components, file operations, creating DLL applications, two-layer database applications, multi-layer database applications, socket programming, and serial programming; in combination with the application development technology and experience of the material management information system project, this article describes in detail the development of general modules of software for general management information systems, including Chapter 10: overview of material management information system and its overall framework design, material management information system background database design, application server implementation, client application design, dynamic connection to application server implementation, general permission management module design, general query component and report module creation, general basic data maintenance module design, material management information system business operation module design, integrated query module design. Based on a certain degree of Delphi knowledge, readers can quickly improve the programming capability and practical development level of Delphi through the study of this book. This book is applicable to readers with preliminary programming ability, and can also be used as a guide for graduation design of senior students in colleges and universities. The website of China Water Conservancy and hydropower Publishing House (www.waterpub.com.cn) contains examples in the book and source code files of a complete Material Management Information System, which provides readers with easy learning, it also provides shortcuts and references for the actual application development of software developers.
