Problems solved by technology

In addition, when using the solution of the existing technology, if a new data model needs to be added, the resulting cost is also relatively large, because it is necessary to define conversion rules between the new data model and all old data models, if the original system There are n different data models in the database. To add a new data model at this time, you need to add n sets of corresponding data conversion rules.

Embodiment Construction

[0036] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] One of the core ideas of the embodiments of the present invention is that when data in the first data model library needs to be converted into data in the second data model library, the data in the first data model library is acquired, wherein the acquired data The structure is a first data structure; the structure of the obtained data is converted from the first data structure to the intermediate data structure of the intermediate model database; the structure of the obtained data is converted from the intermediate data structure to the second data structure of the second database; The converted data with the second data structure is saved in the second data model repository. In this application, when converting the data i...

Abstract

The embodiment of the invention provides a method and a device for data processing. The method comprises the following steps: when data in a first data model base need to be converted into the data in a second data model base, obtaining the data in the first data model base, wherein the structure of the obtained data is of a first data structure; converting the structure of the obtained data into a middle data structure of a middle model data base from the first data structure; converting the structure of the obtained data into a second data structure of a second data base from the middle data structure; storing the converted data with the second data structure in the second data model base. According to the method and device for data processing, the maintenance cost of data conversion is reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data processing method and device. Background technique [0002] In the databases of Internet companies, there are various heterogeneous databases. The properties of various databases are different, so the usage scenarios are also different. For example, some databases are more sensitive and suitable for online updates, and some databases have larger capacity and are suitable for offline backup. Due to the different application scenarios of various databases, some data transfer and interaction are often required between various heterogeneous databases. For example, an online business writes data into database A, and another business needs to read the data from database B. Therefore, the data in database A needs to be transferred to database B. Since the source database and the target database may use different data models, for example, A is a document-based database and ...
