The research of multidimensional analysis based on multi-source heterogeneous real estate data
Yao Zhou, Guohui He · 2018
Through multidimensional analysis of real estate transaction data provided by the government department and some relevant information crawled from the Internet, real estate market's changing rules and trends can be found from different aspects. It is convenient for people to understand real estate's development better. The traditional relational storage mode and analysis method are difficult to be used in the data from different sources and structures. Therefore, as to the problem about storage and multidimensional analysis of unstructured data, we put forward a method using MongoDB for heterogeneous data storage and Pentaho — an open source business intelligence suite — for multidimensional analysis in this paper. The research and application shows that Pentaho can solve the multidimensional problems of non-relational data better, and it is very convenient to make data visualization.
