基于SaaS模式的报表系统

提出一种SaaS模式下的报表系统设计方案。其关键在于结合SaaS多租户、高度复用和报表系统本身架构的特点，系统性地提出SaaS报表系统的架构，将传统的报表功能组件在SaaS下重新进行设计和组合，解决传统报表不能适用大数据量、高复用性和高可用性的问题，并且提出统一数据模型、报表多租户、中立格式导出等解决具体问题的技术手段。在国家电网统一应用开发平台上报表系统得到了应用和验证，取得了良好的效果。

Report System Based on SaaS Model

This paper proposes a typical report system design in SaaS model, the key point is to systematically present a SaaS re- port system architecture by combining the characteristics of SaaS multi-tenant, high reusability and report system architecture. By redesigning and combining the traditional report function components in SaaS model, we solved the problem that the traditional re- ports were not applicable to the situation for large amount of data, high reusability and high usability, and proposed the specific technical means ： unified data model, report multi-tenant, neutral format export, etc. The report system has been applied and ver- ified in the state grid system, and achieves good results.
