An offset pistol scope on the side of the rifle instead of on top , " said terry erwin , the austin - based hunter education coordinator with the texas parks and wildlife department . " this allows their companion behind them to peer over their shoulder and help them sight it , but the blind person can pull the trigger , " he told reuters 得州公园和野生动物部的猎手培训协调员泰里艾温对此解释到"盲人可以使用来福枪，把手枪瞄准镜放到来福枪一侧，这样可以让他们身后的同伴凝视着肩膀，帮助他们观察。
In this thesis , beginning from the practical circumstances of the powermach limited corporation and aiming at a good many problems existing in the production management of this enterprise , wide investigations and analysis of this company were performed and the business flow diagrams , data flow diagrams and function flow diagrams of the system were described in details by using the advanced thought of the existing production management modes home and abroad and the structure of the erp production management systems for reference . based on these , by applying the database modeling tool erwin and java ide jbuilder9 , the design of the database modeling was finished , and eventually , a set of management information system model which could be constructed quickly was established and a set of powermach integrated production management system software based on customization was developed 本论文从强力机械有限公司的实际情况出发,针对该企业生产管理方面存在的诸多问题,借鉴国内外现有生产管理模式的先进思想和erp生产管理系统体系结构,对系统需求进行了深入的实地调研和分析,在此基础之上详细绘制了系统的业务流程图、数据流程图和功能结构图,并应用先进的数据库建模工具erwin和强大的java集成开发工具jbuilder9完成了系统数据模型的设计,最终建立了一套可快速重构的管理信息化体系模型,开发出一套基于客户定制的强力机械集成生产管理系统软件。
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。
Methods : according to the ideas of software engineering and the development strategy of management information system , classic rapid prototyping development method was applied to develop mis , which is divided into 5 phases as following : planning system , analyzing system , designing system , implementing system and maintaining system 方法:借助软件工程思想,结合管理信息系统开发策略,选用经典快速原型法,将整个系统的开发划分为系统规划、分析、设计、实施及运行维护五个阶段。编程采用跨平台java集成工具jbuilder9 ;数据库为适用于中小企业的sql2k ,及erwin建模工具;系统运行在主流的win2k和winxp操作系统下。
Success d eveloped f or t he security s ystem , a11 he sa me t ime t he se curity s ystem h as g ood popularization prospects , ones that adopt rational company rose microsoft company visio and ca company erwin , the modeling software goes on the demand to analyze , business modeling , system modeling , designer modeling , demand and analyze software must have good figure ability , offer many kinds of language formulation ability of codes at the same time 由于系统设计技术较多，开发过程复杂，涉及到软件系统间的兼容问题、数据库安全问题等诸多问题，为保证系统开发的成功，同时保证系统具有良好的推广前景，采用rational公司的rose ， microsoft的visio 、 ca的erwin等建模软件进行需求分析、业务建模、系统建模、设计建模，要求分析软件必须具有良好的图形功能，同时提供多种语言代码的生成能力。
To manage the components effectively , this paper designs and implements the component library oriented ews . in this paper , the key problems concerning library , included component classifying , component query , component storage and library maintenance , is solved according to the characteristics of electronic warfare domain and theory of library management system 为了有效的管理构件,本文设计了面向电子战仿真领域的构件库管理系统,并借助erwin工具进行了构件库系统的设计,为了安全、方便地进行构件库管理和维护,本文提供相关的工具支持。
