Content management (CMS) system, including content management, column management, site management, public message, file management, front-end website display and other functions; Online office (OA) system, mainly provides simple process instances. It provides common tools for encapsulation, including logging tools, caching tools, server-side authentication, data dictionaries, current organizational data (users, organizations, and regions), and other common tools. It also provides a powerful online code generation tool that provides simple single-table, one-to-many, tree-structured functionality that can be used if the appearance requirements are not too high. Using the basic framework can improve the efficiency of rapid development. Built-in functions (only some functions are listed) 1. User management: Users are system operators and configure system users. 2. Organization management: configure the organizational structure of the system (company, department, group), tree structure display, can be adjusted at will. 3. Regional management: system of urban regional models, such as maintenance of countries, provinces, cities, districts and counties. 4.

Connection pool monitoring: Monitor the current system database connection pool status, and analyze SQL to find out system performance bottlenecks. 9. Workflow engine: realize business work order flow and online process designer. The efficient and reliable code generator built into JEESZ drive project supports a variety of data models and generates routine repetitive codes according to database tables, enabling r&d engineers to focus more on the implementation of business logic codes, greatly improving their work efficiency and freeing their repetitive work
