Data association device and data association method

Abstract

The invention provides a data association device which comprises a first analysis unit, a selection unit, a second analysis unit, an information addition unit, a source data set generating unit, a reference data set generating unit, an association model generating unit, a query unit, a value acquiring unit, an address acquiring unit and a value writing unit, wherein the first analysis unit is used for obtaining at least one piece of attribute information of a processed object; the selection unit is used for selecting the obtained at least one piece of attribute information; the second analysis unit is used for carrying out analysis on the attribute information to obtain attribute field information; the information addition unit is used for adding additional field information; the source data set generating unit is used for generating a source data set by combination; the reference data set generating unit is used for generating a reference data set; the association model generating unit is used for generating a multi-level data association model; the query unit is used for generating and executing stitch query sentences to obtain a query result; the value acquiring unit is used for acquiring a result value of a written field; the address acquiring unit is used for acquiring a data address of the written field; and the value writing unit is used for writing the result value into the data address. The invention also provides a data association method corresponding to the data association device. The multi-level association data exhibition is realized in a simple and effective mode.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data association device and a data association method. Background technique [0002] The multi-level data association model is currently applied to multiple business systems. As long as there is association information between tables or objects, or a relationship can be established through an intermediate table or intermediate object, the multi-level data association model can be used to realize the presentation of the entire business. For example, a user interface, in addition to displaying the user's own information, may need to display additional information such as the user's department code and department name, which can be realized through a multi-level association model. In the prior art, the following schemes are mainly adopted: [0003] 1. By adding redundant fields to the application database table, but this solution increases the complexity of the ta...

Problems solved by technology

[0003] 1. By adding redundant fields to the application database table, but this solution increases the complexity of the table, especially if there are many associated fields to be displayed, it is necessary to add many redundant fields to the table, which not only increases the system At the same time, all fields of these associations must be foreseeable. If a business application has been completed, if a field association needs to be added, the table structure needs to be redesigned, which causes great difficulties for maintenance;

[0004] 2. Developers implement multi-table association through programs, which greatly increases the workload of developers, especially when a field is implemented through multi-layer references. For example, the user table needs to display the person in charge of the user's department , if the department table changes, the developed code must be changed accordingly, which greatly increases the workload of the developer;
