Embodiment Construction

[0060] The exemplary embodiments of the present invention will be described below, including various details of the embodiments of the invention to help understand, and they should be considered simply exemplary. Accordingly, it will be appreciated by those skilled in the art that various modifications and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Also, for the sake of clarity and concise, the following description is omitted in the following description.

[0061]With the development of Internet technology, more and more data warehouse models, such as buffering models, basic models, general models, aggregation models, dimension models, and application models, and access to model business primary keys, generally adopted R & D personnel or its maintenance. Model uses a document. However, in the case of the new model, it is difficult to predict which fields of the primary key; and find the research and ...

Abstract

The invention discloses a model primary key prediction method and device, and relates to the technical field of big data. A specific embodiment of the method comprises the following steps: extracting data of a predicted primary key from a model; analyzing and processing the data of the predicted main key to obtain the component proportion of each main component; and determining a predicted model primary key according to the component proportion of each principal component and the corresponding relationship between each principal component and each field in the model. According to the specific implementation mode, prediction and positioning of the model major key can be quickly realized when a new model of an unknown service and a plurality of model fields are provided, so that a subsequent model user can conveniently analyze the model granularity, clarify the model service and the like, and support is provided for developing and designing a data model.

Description

Technical field [0001] The present invention relates to the field of large data technology, and more particularly to a prediction method and apparatus for a model primary key. Background technique [0002] The model primary key (the primary key) is used to uniquely identify a record in the model. Model primary key includes model service primary keys, model service primary keys are fields with business logic meaning, for clarifying model particle size, facilitating downstream analysis and data model design development. [0003] The existing way to get the model business primary key is mainly used by consulting model R & D programs or models their maintenance. However, when the business of the new model does not understand, and the type and number of models are more, it is difficult to find the research and development personnel of the model, or the model is handed over, the new model person in charge will understand the model information, resulting in the master key for the acquis...
