Software features
Powerful data window (DataWindow) technology
Simplified data operations: You can insert, modify, delete, query and generate reports through the data window without writing SQL statements.
Rich data display styles: Supports various data display methods such as tables, charts, and free formats to meet different business needs.
Efficient data binding: The data window is bound to the database table, and developers can quickly build a data interface through drag-and-drop operations.
Object-oriented programming (OOP) support
Object model: supports class definition, inheritance, encapsulation and polymorphism to ensure the reliability and maintainability of applications.
Scalability: Developers can construct new user objects by themselves, expand system predefined objects, and improve development efficiency.
Cross-platform and cross-database support
Multi-operating system support: Applications can run and be distributed on multiple operating systems such as Windows and UNIX.
Multi-database connection: Supports large databases such as Oracle, SQL Server, Sybase, and DB2, as well as small databases such as FoxPro, and can be flexibly accessed through the ODBC interface.
Rich user interface components
Visual design tools: Provides standard controls such as buttons, text boxes, and list boxes, as well as advanced controls such as data windows, and supports drag-and-drop interface design.
User-friendliness: The interface design is user-centered and provides an intuitive and easy-to-understand interactive experience.
Powerful debugging and development tools
Built-in debugger: supports single-step and breakpoint tracking, and can view and modify variables and object properties.
Code generator: Automatically generate commonly used codes to reduce development workload.
Version compatibility: Supports smooth upgrade from earlier versions to protect user investment.
Software function

ActiveX and OLE support: Integrate third-party components to improve application flexibility.
API and plug-in mechanism: Provides rich API and plug-in mechanism to support integration with other systems.
FAQ
Query results are returned slowly
Reason: Database performance problems, such as excessive load, inefficient query statements, and missing indexes.
Solution: Optimize query statements, add necessary indexes, and adjust database configuration to improve performance.
Data window freezes when processing large data sets
Reason: The data window is not optimized, resulting in inefficient processing of large data sets.
Solution: Optimize the data processing logic in the data window, or consider loading data in pages.
