Software development application data management method and system based on cloud computing

Abstract

The invention discloses a software development application data management method and system based on cloud computing, and relates to the technical field of data management, and the method comprises the following steps: carrying out multi-language grammar analysis on a source code, generating a standardized AST, traversing AST nodes to identify a cross-file calling relationship, and establishing a dependency graph between files; dividing fragments on the basis of an AST logic unit, calculating an edge weight on the basis of a file dependency graph, and generating clusters meeting fragment constraints through a graph dimensionality reduction and clustering algorithm; the AST nodes are structured and serialized, data compression is achieved through dictionary compression and duplicated code template replacement, duplicated codes are recognized through subtree hash, and a fingerprint database is generated; according to the method, the file priority weight is calculated according to the AST node type and the function circle complexity, the priority queue is generated, bandwidth resources are dynamically allocated based on the priority weight and the stage coefficient, and the problems of I / O delay, bandwidth waste, low metadata management efficiency and the like caused by low small file processing efficiency in the prior art are effectively solved.
