Abstract

The invention provides a data query system which comprises a data source device, a data entity device and a service data object device, wherein the data source device is used for providing initial data; the data entity device is used for quoting the initial data provided by the data source device, defining computation rules of the initial data and generating a data entity; and the service data object device is used for calculating service data according to the entity attribute of the data entity and data authority rules. By adopting the technical schemes, O / R Mapping, namely the mapping between an object in OOA / OOD and a two-dimension data list is realized. As layered processing is done, each layer can be redefined under the situation of not influencing other layers, a service data object layer, a data entity layer and a data source layer can be changed flexibly according to actual requirements, and the upper application is not influenced. The data entity and the service object after mapping can be reused highly among different service systems, thereby avoiding the repeated construction. As the data query system integrates the support of data authority, different service data can be provided according to authority levels of users, thereby providing the highest data security.

Description

technical field [0001] The present invention relates to data query technology, more specifically, to a data query system and a data query engine device. Background technique [0002] O / R Mapping (Object Relational Mapping, object-relational mapping) is a problem that most software systems need to deal with. Currently, there are many ways to implement object-relational mapping, but most of them only implement structural mapping. Insufficient consideration of sex and data reusability. In the ERP software system, the amount of data is large and the structure is complex. There is an urgent need for a method that can not only effectively map objects and relational data, but also provide sufficient support for the reusability of mapped data and the ease of mapping. support. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a data query system, including: a data source device for providing original data; a data ent...
