Identification method of database associated elements and establishment method of data structure chart

The invention discloses an identification method of database associated elements and an establishment method of a data structure chart. The method comprises the following steps: determining a to-be-detected target element; analyzing target elements on the basis of a data structure chart of the database instance, obtaining associated elements associated with SQL elements associated with the target elements, wherein data structure chart comprises a vertex set and an edge set, the vertex set at least comprises vertexes used for representing the SQL elements in the database instance, and the edge set at least comprises edges used for representing the incidence relation between the SQL elements; and outputting the associated element corresponding to the target element. According to the method and the device, the technical problem that a scheme for effectively identifying the related SQL request does not exist in the related technology is solved. 本发明公开了一种数据库关联元素的识别方法及数据结构图的建立方法。其中，该方法包括：确定待检测的目标元素；基于数据库实例的数据结构图对目标元
