• Chaper i the research status of relative technologies of the patrol system is firstly introduced , then the problems and shortcomings existed in the patrol system of log are analysed , finally the research contents are expended , with which followed a brief introduction to the dissertation ' s architecture . chapter ii based on the analysis of available patrol data models , the primary object - oriented thoughts and modeling techniques are used to build the patrol data model . a conceptual model in patrolling loc is constructed
  第二章，在对已有巡检数据模型分析的基础上，运用面向对象基本思想和建模技术，提出了面向对象的巡检数据模型，建立了巡检概念模型，定义了抽象数据类型，对巡检基本对象、关联对象用类的方式进行了描述，并用巡检类图表示类之间的关系，分析了面向对象巡检数据模型的特点。
• We introduce detailly the its design ideal , merit , purpose and sql language and so on , then we discuss the problem of the design and implement of the v - ordbms . compared with other products , now , v - ordbms , which we are designing , is based on the relational database system for windows os , it extends the abstract data type , such as array , set , structure etc , we solve the store and all sorts of sql operation for these extended data type . otherwise , in v - ordbms , we provide the solution of how to realize the store of class , inherit , and the mapping of the relation among classes . etc . it provides the visual environment for using
  对比国外的postgresql ， gemstone ， 02等产品，目前我们设计的v - ordbms原型系统是基于windowsos的平台，以关系数据库为基础，在支持传统数据类型的基础上扩展了抽象数据类型adt ( abstractdatatype ) ，例如数组、集合、结构等，解决了它们的存储以及相应的各种sql操作，能够支持复杂对象，所以它的数据类型丰富。
