Research Of Modeling Methods And Technology For BI

Business Intelligence (BI) is a broad category of applications and technologies for gathering, storing, analyzing, and providing access to data to help enterprise users make better business decisions. BI applications include the activities of decision support systems, query and reporting, online analytical processing (OLAP), statistical analysis, forecasting, and data mining. Modeling technology is one of the most important technologies of Business Intelligence. Business intelligence modeling is mainly to create multidimensional data model. Many business intelligence applications are based on the multidimensional data model, like Data warehouse, ETL process, data analysis and data mining. In order to allow users create multidimensional data model more easily. Based on Model Driven Architecture (MDA) this article analyzes visual modeling methods and techniques, and analyzes multidimensional data model, implemented a visualization tool for BI.This paper analyzes and designs the multidimensional data model. Design the structure of XML-based description language to describe the multidimensional data model and the storage structure of the model. Design graph information, include business information, display properties, event monitoring information, XML model system conversion, mapping information, relationship information. Implementation the conversion of the model map, model and background data. Finally, model visualization techniques are discussed.In this paper, we discuss the interactive tasks in the process of visual modeling. First, we designed the interactive tasks of canvas. Second, we design and analysis the interactive between client and server, and introduced the event handling mechanism of transmission between the client and server-side. Finally, the framework and implementation of the client and server-side communication is given.In this paper we used Flex framework and Java. Flex is a highly productive, free, open source framework for building expressive web applications that deploy consistently on all major browsers, desktops, and operating systems by leveraging the Adobe Flash Player and Adobe AIR runtimes.
