Research On Information Management System Based On DataSnap Three-tier Architecture

Multi-tier architecture is one of the most popular software architecture models today,which is widely used in the development of various types of software.Traditional multi-tier architecture software development have duplication of code,the development of low efficiency and other issues in the actual development process.Therefore,taking the most representative information management system in multi-layer architecture software as research object,we proposes a templatized rapid software development method based on the DataSnap three-layer architecture through the current situation of multi-layer software development in this paper.The topic analyzed the advantages and feasibility of DataSnap architecture based on the principle of the DataSnap architecture and the actual usage requirements and usage scenarios of information management system and discussed the application of custom components in the system development process by the study on the development of Delphi components deeply.The components become the development elements that can directly implement specific functions by given the system-high-performance functions through the component development technology.The rapid development template was formed by the custom components and the DataSnap data components through a series of specific rules.That set up the overall framework of a college information management system based on the DataSnap in this paper.Completed the overall system development by the rapid development of the template method.Compared with the traditional way of developing information management system,the templated rapid development method has obvious advantages both in system development efficiency and system reusability,and the overall system development efficiency is increased by more than 50%.At the same time,the DataSnap-based three-tier architecture provides reliable data security and fast data transmission support for the system.It is shown that the templated rapid development method based on DataSnap three-tier architecture proposed in this paper can greatly enhance the system development efficiency and increase the flexibility and reusability of the system in the process of development by practice.The developed information management System achieved the desired results,have good performance in data security,transmission efficiency and system update and maintenance.It proves that the templated rapid software development method based on DataSnap three-tier architecture is an excellent software development model,which can provide a good demonstration for the development of multi-tier architecture software in the future.
