更新数据

The system , according to the approach and method of the software engineering on geography information system ,is under scientific system analysis and design combining with Duoluokou Market Information System's self-characteristic and is based on Ajax. Ruby on Rails framework will be applied to manage the date information. Such framework provide several ways to record data information and organize them in an efficient way and to do management, update, maintenance on them; Date information are visible that means the framework provide some operating function on map such as maximum, minimum and brose, user can use the button above the map to imply those function; Information query and brose, a corresponding entity will be offered according to the input terms and its location in the map.

系统按照地理信息系统软件工程的思路与方法，结合舵落口大市场信息化建设的自身特点，对其进行科学的系统分析与设计，并以Ajax技术为基础，利用Rails框架实现了数据信息管理，即运用多种方式录入数据信息，以有效的数据组织形式进行数据库管理、更新、维护；实现了信息查询与浏览，即提供根据输入的条件查询其对应的实体的相关属性；实现了数据信息可视化，即提供了放大、缩小、漫游等基本地图操作功能，用户可以利用地图上方按钮来方便的使用这些功能以及在地图中定位与显示所查询的目标物。

This system is divided into two roles, the one is manager and other role is bursar. Manager can add bursars and keepers. The can also delete or ban a bursar to login this system, at the same time, the manager can add and update Department, Category, Add Mode, Depot, State, Deal with Mode, search assets, Statistic assets, change the password, deal with apply, if the asset "use age" passed the bursar can apply to deal with the asset. Then the manager can see the assets that bursar apply.

在系统管理中可以实现多增加多用户和密码管理；在数据更新中可以添加、删除和修改数据；在数据查询中可以分别按不同条件查询数据；在系统中当物品的使用年限到了，会计就有权力对物品进行清理申请，这时经理就可以接到这个申请，再进行审核，如果同意，他只要点一下鼠标就可以对次申请进行审核，如不同意，他就必须说明原因。

Further, a center holds the latest version of program and at least one item of difference data, and transmits the whole data of program or difference data corresponding to a program version in a terminal apparatus, and the program is updated in the terminal apparatus using the received data.

还在中心保持最新程序的全部数据和至少一个相差数据，并且根据终端装置内的程序版本发送程序的全部数据或相差数据，终端装置则用收到的数据更新程序。

To construct a data warehouse supporting group decisions, a model of multi-data warehouse supporting group decisions was proposed based on limitation analysis of the traditional data refresh algorithm and data warehouse model.

为了构建支持群体决策的数据仓库，分析了传统数据更新算法及数据仓库模型的局限性，提出了一个支持群体决策的多数据仓库模型。

The module of data managementintegrates and renews planning data and basic data. The modules of month production planning and produc2tion scheduling have production planning and production scheduling programmed. C onsequently productionplanning and production scheduling can be quickly and effectively obtained. The module of rolling planning responses promptly to the change of information and makes rolling planning possible.

数据管理模块实现计划数据与基础数据的集成以及数据的及时更新；月本论文由无忧论文网 www.51lunwen.com 整理提供计划编制与生产作业计划编制模块使计划工作程序化，实现计划的快速有效编制；计划滚动模块及时响应信息的变更，实现计划的滚动编制。

In order to exchange data between the disconnected databases in the condition of physical isolation,this paper classes that as bidirectional mirror exchange and unilateral superadd, and emphasizes on discussing the method of data consistency between mirror database , the types and resolvent of conflict caused by data update, and the method of relation consistency among tables in unilateral superadding.

为了实现在物理隔离条件下非连接数据库之间的数据交换，该文将数据交换分类为双向镜像和单向追加两类，重点论述了镜像数据库数据一致性的方法、数据更新冲突的类型和解决以及单向追加时表间链接关系一致性的维护方法。

The digital map input and maintenance subsystem performs format conversion,editing and updating of spatial data;the rail-track video playing subsystem uses video recording as reference data,then plays,inquires and traces the corresponding frames in synchronous to the scaled mileage,realizing the query of the active picture frames;the digital map query subsystem fulfills the map query,preview and spelling of digital map orthograph.

其中，地形图输入与维护实现了数字地图的格式转换、编辑处理以及空间数据的更新操作，解决了不同格式空间数据的互相转换问题；线路录象播放将线路录像数据作为系统的一种索引数据，活动影像的画面与里程相对应，实现了基于线路录像的播放、查询和检索的功能，实现了基于活动画面的查询检索功能；数字地图子系统完成了图形查询、数字地图与线路正射图像浏览、图幅拼接等功能。

Superimposing geographical name data on image data to analyze can judge the change...

将影像数据与地名数据叠加分析，可以判断出实体的类型、位置的主化，并分析实体与地名数据的匹配情况，从而达到监测地名变化的目的，为地名数据更新提供新的手段。

The system makes use of the procedure design method that face to the object in design process, renewing the data, the data inputs, the data checks to seek, the data tidies up to output with data etc.

系统在设计过程中利用面向对象的程序设计方法，将数据更新、数据输入、数据查找、数据整理与数据输出等多项功能集为一体。

The data in data warehouses and data marts is usually updated frequently, and the data loads are typically very large.

数据仓库和数据集市中的数据通常会频繁更新，因此数据加载量通常会很大。
