Problems solved by technology

[0004] At present, enterprises manage metadata mainly by maintaining Excel files. Once the amount of data increases, the efficiency of calling metadata is extremely low. Moreover, the maintenance of Excel files will become more and more complicated, which will affect the metadata in the enterprise. management and use

Embodiment 1

[0029] figure 1 It is a schematic flowchart of a method for invoking metadata provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of invoking metadata. The method can be executed by a metadata invoking device, which can use software and / or implemented in the form of hardware, the hardware may be an electronic device, and optionally, the electronic device may be a mobile terminal, a PC terminal, and the like.

[0030] like figure 1 As described, the method of this embodiment specifically includes the following steps:

[0031] S110. When a metadata call request is received, determine a target call model from a pre-built model library according to the metadata call request.

[0032] Wherein, the metadata calling request may be an instruction or code generated for calling the required metadata when it is desired to call the metadata. A model repository can be a pre-built database for storing the models required to invoke metadata. ...

Embodiment 2

[0045] figure 2 It is a schematic flowchart of a method for invoking metadata provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, this embodiment focuses on the determination method of the target invocation model, the determination method of the target invocation sub-model, and the target metadata For the acquisition method, please refer to the technical solution of this embodiment. Wherein, explanations of terms that are the same as or corresponding to the above embodiments are not repeated here.

[0046] like figure 2 As described, the method of this embodiment specifically includes the following steps:

[0047] S210. When a metadata call request is received, parse the metadata call request to determine a target model item and attribute information corresponding to the target model item.

[0048] Wherein, the target model item may be information for determining required metadata, for example: time range, identification ran...

Embodiment 3

[0085] image 3 A schematic structural diagram of a metadata invoking device provided by Embodiment 3 of the present invention, the device includes: a target invocation model determination module 310 , a target invocation sub-model determination module 320 , a target metadata determination module 330 and a metadata feedback module 340 .

[0086] Wherein, the target invocation model determination module 310 is used to determine the target invocation model from the pre-built model library according to the metadata invocation request when receiving the metadata invocation request; the target invocation sub-model determination module 320 is used to determine the target invocation model according to the The target call model determines at least one target call sub-model; the target metadata determination module 330 is configured to determine target metadata corresponding to each target call sub-model according to the at least one target call sub-model; metadata feedback Module 340...

Abstract

The embodiment of the invention discloses a metadata calling method and device, electronic equipment and a storage medium; the method comprises the steps: when a metadata calling request is received, determining a target calling model from a pre-constructed model library according to the metadata calling request; determining at least one target calling sub-model according to the target calling model; determining target metadata corresponding to each target calling sub-model according to the at least one target calling sub-model; generating target feedback information according to the target metadata, and feeding back the target feedback information to a target terminal corresponding to the metadata calling request. By means of the technical scheme, the technical effects of effective management and calling of the metadata are realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data management, and in particular, to a metadata calling method, device, electronic equipment, and storage medium. Background technique [0002] Metadata refers to the data that describes the data. It can be understood as data with a wider range of data than the general meaning. It not only indicates the type, name, value and other information of the data, but also further provides the context description information of the data. For example, the domain of the data, the source of the data, and so on. In the management information system, metadata is the foundation of enterprise intelligent information construction and the smallest unit of data. Metadata may specifically include technical metadata and business metadata. [0003] In the enterprise management information system, metadata can help enterprise users find the data they need conveniently. Data can be aggregated and i...
