Problems solved by technology

Most of the existing research on metadata focuses on information management in a specific field, or semantic-based retrieval methods, and does not apply metadata to the integration and integration of data resources between different systems, so the scope of application of the method is narrow. poor scalability

[0016] (1) Specify the metadata specification

[0017] Formulate a metadata specification that conforms to the characteristics of the industry and has universal adaptability; the format of metadata is XML, so the metadata specification can be defined by XSD files. The metadata specification should at least specify: identifier, language, character set, contact party information, creation date, version, dataset information and Web Service interface definition. All data sets in the same application system are described by metadata, and a piece of metadata corresponds to a data set. The following XSD file fragment gives the definition part of the dataset information:

Abstract

Provided is a unified management method for large-scale cross-platform heterogeneous data. Firstly, a metadata standard which accords with industry characteristics and has universal adaptability is made according to the conditions of existing data sets, and all the data sets in different application systems are described through metadata, wherein one piece of metadata corresponds to one data set; then, the application systems provide metadata access modes and entity data access modes for the outside; finally, a unified user entry is established to achieve data sharing and access functions based on the metadata.

Description

technical field [0001] The invention relates to the field of computer information technology, and relates to a unified management method for cross-platform large-scale heterogeneous data. Background technique [0002] With the development of information construction, various industries or departments have built numerous application systems. These systems are generally decentralized and independent. In order to obtain a certain statistical data, users often need to enter different systems, which is inconvenient and inefficient. With the continuous advancement of information technology, people hope to integrate the original independent and different systems to realize data sharing on the logical level and improve work efficiency. [0003] Metadata is a kind of structured information, which is used to describe, explain and locate an information resource, making it easy to extract and use. Using metadata to abstract and summarize heterogeneous data will facilitate the integra...
