采用OLAP技术的在线监测监控系统智能报表的研究(Ⅱ)——系统设计、源代码组成和查询命令

A STUDY OF INTELLIGENT REPORT SYSTEM ADOPTING OLAP IN ON-LINE MONITORING AND CONTROL SYSTEM(Ⅱ)——SYSTEM DESIGN,CODE CONSTITUTION AND SEARCH COMMAND

OLAP的功能是面向数据的查询、分析、归纳和总结,用于决策支持和知识发现。本研究组开发的智能报表系统实现了类似OLAP的数据分析和查询功能,总称为SAP系统。SAP采用C/S模式。智能报表系统允许用户按自身需求定制报表,按报表要求对数据进行查询和分析,提供数据的格式化输出和多风格的打印。系统支持MDX(多维表达式)查询,对多个维度的数据的访问更为简单和直观。

OLAP(On-Line Analysis Processing)executes data search,analysis,induction and conclusion,and is used in decision science and knowledge finding.Our team developed an intelligent report system which is able to perform functions like data analysis and research through OLAP and called SAP system.The SAP adopts C/S mode.The intelligent report system allows self-defined report,data search and analysis according to report requirements,and to provide data-formatted output and Stylish report print.The system is supporting MDX search,which make operation on multi-dimension data easier and more direct.
