机助软件工程模型库及其分类体系在地质矿产点源数据库系统（ＧＭＰＤＢＳ）的设计、开发和运行中起着重要的作用．模型库是各个软件设计阶段的程序集成器和信息传递转换器，模型库分类体系的建立使全部模型库中错综复杂的属性、关系和结构信息条理化、程序化，使整个系统脱离混乱状态而变得有序，实现了开发—运行—维护一体化．机助软件工程模型库及其分类体系的应用，是系统结构、系统功能、模型结构和应用模型等实现参数化的方法基础，也是建立地矿点源数据库管理系统机助软件工程（ＧＤＣＡＳＥ）的技术基础．论述了机助软件工程模型库及其分类体系的内涵、功能、结构组成、设计思路与方法，以及它在地矿点源数据库系统（ＧＭＰＤＢＳ）中的地位．这一技术成果在其他ＭＩＳ的开发中，同样具有广阔的应用前景
The software engineering model library and its classification system play an important role in the design, development and operation of Geological Mineral Point Source Database System (GMPDBS). The model library is a programmer and information transfer converter in each software design stage. The establishment of the model library classification system makes the entire system model complex and proceduralized so that the entire system is out of chaos. Orderly, to achieve the development - operation - maintenance integration. The software engineering model library and its classification system are the basis for the method of parameterization of the system structure, system function, model structure and application model, as well as the establishment of GDCASE (Geo-point Source Database Management System Software Assisted Software Engineering) technical foundation. This paper discusses the connotation, function, structure, design ideas and methods of software-assisted software engineering model base and its classification system and its position in GMPDBS. This technical achievement in the other MIS development, also has broad application prospects
