Model conversion frame supporting separation of conversion engine and mapping rule and the method

Abstract

The invention discloses a model conversion device and method supporting the separation of conversion engine and mapping rules. The device includes a model extractor, and further includes: a target platform manager, an agent rule manager, a mapping rule query engine, and a mapping rule library , mapping rule editor, mapping rule execution engine, script combiner, script interpreter and public data area; proxy rules pass model elements to the mapping rule query engine, and the mapping rule query engine queries the mapping rule base according to the model elements to obtain the model elements The corresponding mapping rules and proxy rules will then hand over the model elements and mapping rules to the mapping rule execution engine for processing; the mapping rule execution engine will send the processed target script file to the script combiner for merge processing to generate a target script file; script The interpreter interprets the target script file to generate the target model or code. The invention realizes the separation of the model transformation engine and the mapping rule.

Description

technical field [0001] The invention relates to the technical field of computer software development, in particular to a model conversion device and method based on a Model Driven Architecture (MDA) that supports the separation of a conversion engine and a mapping rule. Background technique [0002] At the end of 2002, the Object Management Group (OMG) proposed a new system software development methodology—Model-Driven Architecture (MDA). The core idea of ​​this architecture is to separate the business function logic of the system from the implementation platform technology to avoid tight coupling between business logic and implementation technology. At the same time, MDA can map the platform-independent system function model to different implementations through model conversion technology. On the platform model, the conversion to specific code is finally realized. So that the portability, interoperability and reusability of the software system can be maintained for a long ...

Problems solved by technology

[0008] No. 0130011, 0130009, and 0130008 U.S. patents have the following disadvantages: these three patents are all aimed at different technical aspects of the same conversion engine, and their main disadvantage is that the conversion engine and conversion rules are bound together. The conversion technology only realizes the reuse on the same rule set (that is, all the conversion rules in a conversion engine process the same source meta-model and the same target meta-model), and the source model based on the same meta-model should be converted into When the target model is based on a different metamodel, a new transformation engine and corresponding transformation rules must be redeveloped
