Problems solved by technology

[0004] There is a dependency relationship between the data of the task, for example, the execution sequence relationship between the upstream task and the downstream task. Execute tasks in order, so programmers need to determine dependencies when writing data processing tasks, otherwise it will cause execution errors of SQL statements, resulting in a problem of low fault tolerance

Abstract

The invention discloses a dependency relationship analysis method, an electronic device, a computer device and a readable storage medium, and the method comprises the steps: obtaining a data processing task, and generating a corresponding structured query language script file according to the data processing task; analyzing each structured query language statement in the structured query languagescript file to obtain a genealogy tree corresponding to each structured query language statement; obtaining keywords, a target table and a source table according to the genealogy tree; and according to the keyword, obtaining a dependency relationship between the target table and the source table. By applying the embodiment provided by the embodiment of the invention, the dependency relationship can be automatically analyzed, errors caused by manual search are reduced, and the analysis speed, the analysis efficiency and the quality are high.

Description

technical field [0001] The present invention relates to the technical field of dependency analysis, in particular to a dependency analysis method, electronic device, equipment and storage medium. Background technique [0002] Relational database is a database based on the relational database model. It uses mathematical concepts and methods such as set algebra to process data in the database. Now the mainstream relational databases include Oracle, Sql Server, MySQL, etc. Dependency: Indicates that there is a foreign key dependency between tables in a relational database. The definition of a relational database results in a table of metadata or in a formal description of tables, columns, scopes and constraints. [0003] Due to the variety of development languages ​​supported by the data platform technical framework of the relational database, many different types of tasks (programs) are generated to run on the big data platform, such as: MapReduce, Hive, Pig, Spark, Java, She...
