The Analysis & Design Of The Multidimensional Information System Based On LC Model

Online Analysis Process is an important technique in building MultiDimensional Information System by which data analyst can have fast, consistent and interactive access to the data and get all kinds of multidimensional view of information. Hence, the inner relationship between data and the rules hidden behind them can be found out and then decision-makers can be provided with much stronger decision supports. Since the concept of OLAP has been put forward, the multidimensional information system which is based on OLAP technology have developed rapidly in the past few years and the range of the multidimensional information system have been expanding. But the status of the multidimensional information system in our country is on the reporting and OLAP level which is a quite low level.The paper represents the multidimensional information system framework (ISFx). The ISFx framework is based on the Located Contents Model and makes the model as extensible as possible. The framework can be divided into five layers: Basic Services Layer, Integration Services Layer, Analysis Services Layer, Business Space Layer and Analysis Library Layer. The Basic Services provides the common services for other parts. Business Space establishes the mapping between the customer's requirements and analysis services databases, the relationship between the integration services and data source. Integration Services is a common and extensible ETL data access interface. Analysis Services is a common and extensible online analysis services data access interface. Analysis Library is based on the Located Contents Model. Many statistical methods are imported and applied to data analysis process, which are stored in the Analysis Library. Not only simple information, such as data counting and summary, but also the inner relationship between data can be obtained from analysis results got by using these methods. Hence, the development trend can be learnt, which improve the scientific decision.The paper not only introduces the LC model but also makes further study of the multidimensional information system base on the LC model and implements the analysis and design of the architecture of multidimensional information system framework.
