Data consanguinity analysis method, device and equipment and computer readable storage medium

The invention relates to the technical field of big data, and discloses a data consanguinity analysis method, device and equipment and a computer readable storage medium, which are used for meeting data consanguinity analysis requirements of different types of databases in production practice. The method comprises the steps of obtaining an input table and an output table of a structured query language (SQL) statement executed on a big data platform at present, and consanguinity between the input table and the output table; respectively converting the input table and the output table into entity objects under a preset type system, and storing the entity objects into a preset graphic database; according to the consanguinity, constructing a consanguinity map between the entity objects in a graphic database; receiving a mapping relationship between the service source table and the big data table sent by the data access platform; determining a target entity object node of the ancestor nodeto be added in the consan
