Embodiment Construction

[0035] Dimensional model is a data modeling method in data warehouse construction. Through the dimensional model, the data of multiple systems of the enterprise are isomorphically correlated according to business needs. The dimensional model is mainly composed of two basic elements, the fact table and the dimension table; the fact table is a basic table used to store a large number of business measurement values. Fact tables are usually stored in HBase in the form of wide tables, and HBase is columnar storage.

[0036] After research, the inventor found that the above isomorphic data storage method makes it difficult to split the data after the isomorphic association is completed. Once a certain isomorphic field is configured incorrectly, it will be difficult to correct the data. In order to solve this technical problem, the present invention provides a data storage method, which maintains two types of tables: data table and isomorphic relationship table; the data table is us...

Abstract

The invention provides an isomorphic data storage method and device. According to the scheme, two types of tables, namely a data table and an isomorphic relation table, are maintained, wherein the data table is used for storing each piece of independent data and does not reflect the isomorphic relationship between the data; the isomorphic relationship is stored and maintained by an isomorphic relationship table. By adopting the storage mode, the numerical value part and the isomorphic configuration relationship of the data are respectively stored in the two tables, and the data tables directlystore the data according to the fields (such as the identification information of the fields) of the original data in the system. According to the scheme, the data and the isomorphic relationship aredecoupled, and the data and the isomorphic relationship are independently stored and maintained respectively. And if the isomorphic relationship configuration is wrong, only the corresponding isomorphic relationship in the isomorphic relationship table needs to be modified, so that the technical problem that the isomorphic relationship cannot be modified in a traditional isomorphic data storage mode is solved, and the flexibility of isomorphic data is improved.

Description

technical field [0001] The invention belongs to the field of computer technology, and in particular relates to a method and device for isomorphic data storage. Background technique [0002] Data isomorphism refers to associating a field in data from different systems. For example, if field A in system 1 and field B in system 2 have the same physical meaning, field A of data 1 in system 1 can be isomorphically associated with field B in data 2 in system 2, and the isomorphic Field creates a new field id, for example, the field id created for isomorphic field A and field B is field C. And the isomorphic data 1 and data 2 are stored in the isomorphic data table according to the newly created field id identifier, that is, in the isomorphic data table, the field value corresponding to the field after the isomorphic association is stored in the newly created field in the column corresponding to id. This storage method of isomorphic data makes it difficult to split the isomorphi...
