Abstract

The present invention provides a cloud platform data query method. The method comprises: converting data query into equivalent relational algebraic expressions; and then selecting an optimal algebraic expression from the equivalent expressions to perform query optimization processing; and selecting an optimal node path and data transmission mode to perform data interaction between each node of a cloud platform. The present invention discloses the cloud platform financial data inquiring method; transmission is carried out according to attributes so as to reduce time of requesting node connection, a performance optimization effect on a transmission amount and response time is obvious, and data query efficiency is improved.

Description

technical field [0001] The invention relates to financial data processing, in particular to a cloud platform data query method. Background technique [0002] Financial data is an important basis for investors to make investment decisions and securities companies' investment research departments to conduct research. It has always been a long-term and arduous challenge for relevant departments to provide timely, accurate and easy-to-use financial data for corporate customers and investment research departments . With the advent of rich information on the Internet and the era of big data, financial data currently contains a large amount of structured and unstructured information, and the increment is huge. With the rapid development of cloud computing network technology, in order to avoid the loss of useful data information, it is necessary to establish a corresponding database as a carrier to store these data. However, because the database based on cloud computing is distrib...
