Problems solved by technology

Concept-level semantic heterogeneity means that different information sources use multiple terms to represent the same concept, and the same term expresses different meanings in different information sources; value-level semantic heterogeneity is mainly due to the existence of different However, due to the distribution autonomy between various information sources, this implicit relationship cannot be reflected

Embodiment Construction

[0035] Such as figure 1 As shown, one of the present invention is realized like this: a kind of method that the heterogeneous data of software platform bottom layer is unified encapsulation, and database middleware comprises intermediary device, wrapper and semantic library; It comprises the following steps:

[0036] Step 1. The intermediary library receives user query request data;

[0037] Step 2. Convert the query request data according to the semantic database;

[0038] Step 3, the wrapper performs query according to the converted query request data, and obtains the query result;

[0039] Step 4: Transform the query structure into query data in a specified format according to the semantic base.

[0040] Step 5. The intermediary processes, synthesizes and removes redundant information from the query data, and then returns it to the user.

[0041] The process of establishing the semantic database: extracting data patterns from the underlying data sources, establishing res...

Abstract

The invention provides a method for packaging underlying heterogeneous data of a software platform in a unified way. The method comprises the steps that an agency library receives query request data of a user; the quest request data is converted according to a semantic library; a packager performs a query according to the converted query request data to obtain a query result; and the query result is converted into query data in a defined format according to the semantic library. The invention furthermore provides a system for packaging the underlying heterogeneous data of the software platform in the unified way. The complexity of upper-layer application development is greatly lowered, and the upper-layer application can only pay attention to business logic realization and does not need to pay attention to an underlying data structure.

Description

technical field [0001] The invention relates to a method and a system for uniformly packaging heterogeneous data at the bottom of a software platform. Background technique [0002] The heterogeneity of data is mainly reflected in four aspects: system heterogeneity, structure heterogeneity, syntax heterogeneity and semantic heterogeneity. Many technologies have been developed to solve these different types of heterogeneity problems. Technologies and methods such as CORBA, DCOM, RMI, federated databases, and virtual databases can solve the first three heterogeneous problems, especially after XML is widely used as a public language standard. A unified data model can be used to exchange information, which effectively solves the problem of data exchange in data integration. [0003] Since different business types and data types of large-scale software platforms often involve the use of different data storage solutions, by encapsulating underlying heterogeneous data operations in...
