Examples
- In the past 30 years , the database system has already developed the no relational model , the next generation object - relational database system ( ordbs ) , the third generation object oriented database system ( oodbs ) . in the 1990s later , for the speed of the internet technique , the website base based on the internet promoted the information resource share
经过30年的发展，数据库系统已经历了第一非关系型数据库、第二代关系型数据库( ordbs )的发展到面向对象数据库系统( oodbs )和各种专业数据库。九十年代后由于互联网络技术的飞速发展，基于互联网的网站数据库技术为信息资源的共享提供了技术上的保障。 - There are two areas innovation in my temporal data modeling . first is developing an arithmetic which implements information modeling by combining erwin tool and timeer model . second , an application - oriented and event - based temporal representational scheme is developed , which has advantages on following aspects : retaining simplicity of relational model , easy of implementation and query evaluation efficiency
一是将timeer模型与erwin建模工具相结合，开发了一个用erwin建模时态信息模型的方法，并对时态约束进行了具体讨论；二是在研究时态数据语义和时态数据关系模式的基础上，结合具体的应用实际开发了人力资源管理信息系统的时态关系模式及其相关的操作算法。 - In autoore , a novel approach to extract java semantic relational model is presented . to get precise object relational result , the java code polymorphism invoke location is formal defined and a program analysis method based on extended class hierarchy graph ( echg ) is proposed
代码抽取是oore的起点，从起点开始支持理解是逆向工程的重要目标， autoore在java抽取中，抽取模型采用文中提出的java词法和语义两个模型，利用一个基于java扩展类层次图( echg )的多态调用点分析算法，得到更精确的静态对象关系。 - Involuntarily , questions of these engineering datas " management appear , datas " persistance only depending relational model and rdbms is greatly insufficient , so this paper carefully studies object - relational mapping based on rdbms based on the analyse of home & overseas actualities , correlative theories and realizing methods of object - relational mapping , we find opl based on rdbms is the most suitable for object relatinoal mapping of clera . based on the engineering application analyse of opl in clera , function requirements , database modes , interface criterions and functions , running modes of opl have being detailedly described . with the framework of microsoft dna , a kind of realizing method of opl based on com / dcom / activex component technology has being brought forward , and this paper describes realizing keys from base tables " definition , object id and class hx class and inheritance of class , object storage , parallel control and affair , object query , object nesting , relations between objects , support of complex data types , right control of object and buffer management of object
本文在分析对象?关系映射技术的国内外现状、相关理论及实现方法的基础上，研究发现基于rdbms的opl是目前最适合clera的对象?关系映射方法；在clera的opl应用分析的基础上，详细描述了opl的功能要求、数据库模式、接口规范与功能、运行方式等内容；结合microsoftdna开发框架，提出了一种基于com dcom activex组件技术的opl实现思路，并从基本表定义、对象标识与类标识、类与类继承、对象存储、并发控制与事务、对象查询、对象嵌套、对象间联系、复杂数据类型的支持、对象级权限控制及对象缓冲管理等几方面概述了实现要点。 - By the review of the proceedings and history of the division of marine functional zonation , this paper gives the summary of the theory and technical methods systemically . to the questions for the concerned criterion , we discussed the objectives and their relations that dominate the results of the division . this paper try to define the spatial relational model ( srm ) and the calculate methods to describe the theory in a digital way
本文回顾了我国海洋功能区划的发展历程，对我国海洋功能区划的成果、理论与方法进行了较系统地总结，针对海洋功能区划中存在的一些问题，作者重新讨论了海洋功能区划的对象及其之间需要处理的关系，本文试图提出空间关系模型并给出海洋功能区划可应用的数量化方法，推动海洋功能区划理论与方法的发展和深化。
