The disclosure provides a cloud computing-based adaptive storage layering system and method. The system includes a data node management module, a metadata management module, an adaptive storage layering module, and a pre-aggregated query routing module. According to predefined rules, node capacity is expanded and shrunk, collected queried hit models and scanned file paths are aggregated and sorted, and layering loading and pre-loading are performed on files. Based on the disclosure, an efficient On-Line Analytical Processing (OLAP) query execution engine may be constructed, to deal with complex OLAP queries of various reporting system. Therefore, the execution efficiency of cloud OLAP engines can be significantly enhanced.
