Method and device for customizing metadata

Abstract

The invention provides a method for customizing metadata. The method comprises the following steps of: (102) determining a service scene when a user operates a service object; (104) determining a filtering rule corresponding to the service scene; and (106) filtering the metadata of the service object through the corresponding filtering rule so as to obtain customized metadata of the service object. The invention further provides a device for customizing the metadata. The device is characterized by comprising a service scene confirmation module, a filter confirmation module and a metadata filtering module, wherein the service scene confirmation module is used for determining the service scene when the user operates the service object; the filter confirmation module confirms a filter corresponding to the service scene; and the metadata filtering module filters the metadata of the service object through the corresponding filter so as to obtain the customized metadata of the service object. According to the technical scheme of the invention, metadata filtering needed by different service scenes can be realized, the customization of the metadata by different users can be supported and the usability and flexibility of a software product developed based on the metadata are improved greatly.

Description

technical field [0001] The invention relates to data processing technology, in particular to a method and device for customizing metadata. Background technique [0002] Current management software products are usually developed based on an application platform, and all use models to a certain extent, but some are based on data models, that is, they mainly use metadata in databases, or data dictionaries. There are certain limitations in the development of metadata based on the data model, because the database is centered on data. Its theoretical basis is relational algebra. There is no clear concept of business objects. Representing business objects with data objects will lead to problems of unclear business meaning and inaccurate expression. Therefore, many software developers have researched and developed application dictionaries based on the analogy of data dictionaries, and describe business objects with business object structures. This method has a certain improvement ...

AI Technical Summary

Problems solved by technology

However, there are also some problems in the application dictionary: the description of the application dictionary does not really reflect the relationship of the business model, such as entity relationship, composition relationship, association relationship, inheritance relationship, etc.

However, using metadata will also encounter some problems. For example, a business entity will have more metadata information. If all the metadata information is displayed in the application, there will be some problems: First, the large amount of loaded data will cause Second, a large amount of metadata information makes it difficult for users to find the content they want, resulting in usability problems

But there is a problem: if the customer application needs to customize the metadata in some business scenarios, it cannot be directly supported, and secondary development must be carried out

[0004] Therefore, there is a need for a metadata processing method that can solve the above-mentioned problem that different users cannot customize metadata in some business scenarios, thereby improving the usability and flexibility of software products developed based on metadata
