Abstract

The invention relates to a construction method and device of a metadata model, computer equipment and a storage medium, and the method comprises the steps: enabling the computer equipment to obtain type domains of unstructured data of various business domains of an enterprise and a first association relationship among the type domains, and then constructing a data association model according to the business domains, the type domains and the first association relationship; And obtaining metadata of the unstructured data according to a preset tetrahedral model, and then adding the metadata intothe data association model to construct a metadata model. By adopting the method, the integration level of the metadata model can be higher, the maintenance is easier, and the construction efficiencyof the model is improved.

Description

technical field [0001] The present invention relates to the field of data technology, in particular to a method, device, computer equipment and storage medium for constructing a metadata model. Background technique [0002] With the development of network technology, electric power enterprises have generated a large amount of unstructured data, including text, video, audio, pictures and other files in different formats. Metadata is used to manage unstructured data, and in maintaining the authenticity of unstructured data, Aspects of completeness, usability, and comprehensibility have received a lot of attention. Among them, metadata is a kind of structured data, which is used to describe unstructured data, so that the unstructured data can be understood and processed by computer equipment. The design of unstructured data metadata model is the key to apply metadata to unstructured data management. [0003] At present, the existing metadata model design method is mainly to a...
