摘要： 随着模型驱动技术的逐渐成熟和广泛应用,大量反映程序结构、行为以及性质的模型产生于软件的开发过程中,并成为软件文档的重要部分保存下来。其中,尤以UML模型的应用最为广泛,也因此形成了通过理解UML模型来理解大规模、高复杂性软件系统的研究思路。对UML模型理解的一个难点是如何有效地从大量复杂的模型中,快速查找并定位具有一定结构特征的模型片段。幸运的是,设计模式的普遍应用为我们快速、高效地理解和定位模型提供了一条重要的线索。然而,随着技术的发展,设计模式数量在不断增长,其自身在应用中的结构也在微妙变化,这些都给相应查询和识别工具的开发带来一定的困难。文中从查询和匹配UML模型中特定结构的角度入手,利用UML自身特点设计相应查询算法,通过分析和理解设计模式的结构特征,从UML模型中查询相应的设计模式,以达到灵活和高效地理解软件系统的目的。
