Developing a visual programming environment in a data analytical system

本研究设计并开发了一个可视化编程环境作为数据分析系统的用户界面。使用该系统，用户可以直观、方便地以链接图标的形式组装和构建数据分析流程。由于采用UML（统一建模语言）作为分析流的表达和内部数据格式，该系统具有可扩展性，能够将分析流程序交换到其他系统。

The research has designed and developed a visual programming environment as a user interface of a data analysis system. Using this system, a user can assemble and construct analytical flows for data as linking icons visually and easily. Because of adopting UML (Unified Modeling Language) as expression of analytical flows and internal data format, this system has extendibility that is capable of exchanging a program of analytical flows to other systems.
