Embodiment approach

[0062] According to a specific implementation manner provided in this specification, the data acquisition module 210 is specifically used for:

[0063] Judging whether the amount of business data stored in the storage medium in which the business system stores business data exceeds a preset threshold;

[0064] If so, obtain multiple pieces of business data from the storage medium in which the business system stores business data.

[0065] According to a specific implementation manner provided in this specification, the value range calculation module 230 is specifically used for:

[0066] Determine the maximum and minimum values ​​corresponding to each field according to the recorded field values ​​and occurrence times;

[0067] The value range of each field is calculated from the determined maximum value and minimum value corresponding to each field.

[0068] According to a specific implementation manner provided in this specification, the field extraction module 240 is spec...

specific Embodiment approach

[0070] According to a specific implementation manner provided in this specification, the determination module 250 is specifically configured to:

[0071] According to the pre-configured field blacklist, extract the fields whose value fields meet the preset requirements again;

[0072] It is determined that the field extracted again is the feature field of the domain model.

[0073] For the implementation process of the functions and effects of each module in the above-mentioned device, please refer to the implementation process of the corresponding steps in the above-mentioned method for details, and details will not be repeated here.

Abstract

A method and apparatus for extracting the feature fields of a domain model is disclosed. The method for extracting the characteristic fields of the domain model comprises: acquiring a plurality of service data, wherein the service data has different fields and each field has corresponding field values; integrating a plurality of different fields from the obtained plurality of service data, and recording the field values and occurrence times corresponding to each field; calculating a value range of each field according to the recorded field value and the number of occurrences; in the integratedfield, extracting the field whose field value domain satisfies the preset requirements, and determining the extracted field to be the feature field of the domain model.

Description

technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular to a method and device for extracting feature fields of a domain model. Background technique [0002] The domain model is a visual representation of conceptual classes in the domain or objects in the real world. It focuses on analyzing the problem domain itself, discovering important business domain concepts, and establishing the relationship between business domain concepts. An abstraction of how entities should relate and collaborate to perform business. Due to the characteristics of the domain model, most of the current business systems are designed using a domain model-driven solution. In the business system, the business roles and business entities involved in the domain model are represented by corresponding fields (words) to represent their specific attributes. The fields are divided into ordinary fields and feature fields. Ordinary fields have n...
