Data interface dynamic generation and execution method based on openEHR Composition template

Abstract

The invention provides a data interface dynamic generation and execution method based on an openEHR Composition template, and the method comprises the following steps: (1), analyzing the Composition template, and obtaining a Composition template object; (2) establishing a combination relationship and an LINK relationship among the nodes in the Composition template object; (3) obtaining a templatemapping information (TRM) object by adopting the Composition template object processed in the step (2) and combining the mapping information of each openEHR template in the Composition template and the database table; (4) generating a data interface according to the template mapping information object obtained in the step (3); (5) analyzing an HTTP request of a client by using the data interface obtained in the step (4) to obtain a template mapping information data instance; and (6) splicing the data instances according to the template mapping information to obtain SQL statements, executing the SQL statements and returning query results to the user. The dynamic interface based on the openEHR Composition template provided by the invention has flexibility and expansibility, can meet complexmedical data access requirements, and has very high theoretical guidance and application value.

Description

technical field [0001] The invention relates to the technical field of computer software data interface generation, in particular to a method for dynamically generating and executing a data interface based on an openEHRComposition template. Background technique [0002] In order to promote and enhance the effective use of medical data, medical institutions are carrying out medical data integration work, integrating fragmented data in medical institutions, and providing data access for upper-level applications. [0003] Their construction method is usually to build a data storage center to integrate data, and then provide data interfaces based on the data storage center to provide support for upper-layer applications. However, the above-mentioned method of providing data access services cannot meet the access requirements of medical data. [0004] A common way to provide data access services is to customize and develop corresponding data interfaces according to data requirem...

AI Technical Summary

Problems solved by technology

[0007] However, there are still flaws in the data interface implemented in this research. The interface is actually generated based on the storage model and can only access the data corresponding to the storage model. In actual scenarios, the access requirements of medical data and the storage model of medical data Inconsistent, therefore, the above data interface cannot meet the data access requirements
