Embodiment 1

[0051] Figure 1A It is a schematic flowchart of a metadata model extension method provided by Embodiment 1 of the present invention. This embodiment can be applied to generate aggregated metamodels that meet various business requirements, so that third-party applications can obtain various In the case of metadata requirements, each aggregated metadata model generated can be used as a new metadata model, and the method can be executed by an extension device of the metadata model, and the device can be realized by hardware and / or software, and the method specifically includes Follow the steps below:

[0052] S110. Acquire each initial metadata based on a metadata model corresponding to each initial metadata.

[0053] Wherein, the metadata model may be a model containing initial metadata. Initial metadata may be data describing data. For example, initial metadata can be data used to describe medical data, such as patient name, test report number, drug chemical name, etc.

Abstract

The embodiment of the invention discloses a metadata model extension method and device. According to the method, each piece of initial metadata is obtained through a metadata model corresponding to each piece of initial metadata, so that at least one piece of to-be-aggregated metadata selected by a user in each piece of initial metadata for a current aggregation demand is obtained, and the at least one piece of to-be-aggregated metadata is aggregated; and generating the aggregation meta-model according to the aggregation processing result, and storing the aggregation meta-model in the platform aggregation database, so that automatic aggregation of each metadata meeting the business requirements is realized, a new metadata model, namely the aggregation meta-model, is generated, a user can directly obtain each metadata meeting the business requirements by obtaining the aggregation meta-model generated by the method, and the user experience is improved. The user does not need to manually search the needed metadata, and the technical problem that in the prior art, different business parties with the same business requirement determine different metadata is solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of metadata, and in particular, to a method and device for extending a metadata model. Background technique [0002] Metadata may be data describing data. At present, in the clinical business platform, the requirements for data are often similar. Taking a scientific research platform for a specific disease as an example, it is necessary to obtain the medication status of patients under this disease for research and follow-up analysis. At this time, the metadata that needs to be used includes patient Basic information and medication status. In addition, when reporting the quality control of special diseases, the metadata that needs to be used also includes the basic situation of the patient and the situation of medication. Two different service platforms need to use two kinds of the same metadata. [0003] At this time, the user usually needs to search the required metadata in the dat...
