Abstract

The present invention provides a multidimensional analysis method based on presto data, the method comprising: S1, modeling all business data in the data warehouse, and mapping the modeled logic model to the data table of the data warehouse middle; S2, according to the logic model, convert the user's query operation into SQL language; S3, submit the SQL language to the presto query engine, and obtain the analysis result. The method provided by the present invention, by storing the data analyzed by OLAP in a data warehouse in a structured form, improves the storage scalability of data, the reading rate of data and the analysis rate, and can also perform real-time performance for data of TB size. Online analysis improves user experience.

Description

technical field [0001] The present invention relates to the technical field of computer data management, and more specifically, relates to a multidimensional analysis method of presto-based data. Background technique [0002] OLAP is online analytical processing. OLAP system is the most important application of data warehouse system. It is specially designed to support complex analysis operations, focusing on decision support for decision makers and senior management personnel. It can be quickly and flexibly according to the requirements of analysts. Complex query processing of large amounts of data, and provide the query results to decision makers in an intuitive and easy-to-understand form, so that they can accurately grasp the business status of the enterprise, understand the needs of the object, and formulate the correct plan. In recent years, OLAP has become a popular method for processing multidimensional data used by data warehouses and business intelligence. [0003...
