Embodiment Construction

[0054] The embodiment of the present invention provides an analysis method and device based on a metadata model, which solves the problem that the current metadata can only support functions such as indicating storage location, historical data, resource search, and file recording. When performing analysis, additional data processing methods need to be used for data analysis, which leads to the technical problem of low integrity of the overall processing of metadata.

Abstract

The embodiment of the invention discloses an analysis method and device based on a metadata model.The technical problems that as present metadata only has the functions of being capable of supporting storage position indication, historical data, resource searching, file recording and the like, and when a metadata needs to be analyzed in the following process, as data analysis needs to be carried out with an extra data processing method, the integrity of whole processing of the metadata is low are solved.The analysis method based on the metadata model includes the steps that a metadata analysis order directly or indirectly triggered through an operation interface is obtained, and the type of the metadata analysis order is determined; if the metadata analysis order is a consanguinity analysis order, associated metadata extracting corresponding to consanguinity analysis is carried out; if the metadata analysis order is an influence analysis order, associated metadata extracting corresponding to influence analysis is carried out; the extracted associated metadata is shown in a list or graph mode.

Description

Technical field [0001] The invention relates to the technical field of big data, and in particular to an analysis method and device based on a metadata model. Background technique [0002] Big data is just a kind of appearance or characteristic of the Internet development to the present stage. There is no need to myth it or keep it in awe. Against the backdrop of the technological innovation represented by cloud computing, these are originally difficult to collect and use. The data of the world is beginning to be easily used. Through continuous innovation in all walks of life, big data will gradually create more value for mankind. [0003] Metadata, also known as intermediary data, relay data, is data describing data (dataaboutdata), mainly describing data properties (property) information, used to support such as indicating storage location, historical data, resource search, file Recording and other functions. Metadata can be regarded as an electronic catalog. In order to achiev...
