This This article presents a quick way to develop your system with custom components in Delphi. Use the above method can minimize code duplication, improve work efficiency. In this paper, we apply this method to the development of information management system in a university based on the Data Snap three-tier architecture. Through practice, we find that the workload of the original three months, and we only need 20 days to complete. Therefore, adopting the rapid software development method based on component design proposed in this paper can not only shorten the programming time of management systems such as ERP and information management by more than two thirds, but also bring great advantages in system development.
