BO是什么?BI是什么?

BO为BusinessObject的缩写,BusinessObject是业务对象层,表示应用程序领域内"事物"的所有实体类。这些实体类驻留在服务器上,并利用服务类来协助完成它们的职责。BusinessObjects,也简称BO,是全球领先的商务智能(BI)软件公司。公司主要业务是帮助企业更加深入地跟踪和了解其业务,改善决策水平,优化企业绩效。BI是生物信息学。是对数据进行检索和处理的组件。是简单的真实世界的软件抽象。业务对象通常位于中间层。业务对象可以在一个应用中自动的加入一个特定的功能来获得增值效应。使知识重用变为可能。比如,如果你要开发一个包含多货币处理的应用,你可以选择使用一个已经开发完成的,包含所有多货币处理功能的业务对象来开始你的开发。使您的开发工作极大的减少。生物信息学(Bioinformatics)是在生命科学的研究中,以计算机为工具对生物信息进行储存、检索和分析的科学。它是当今生命科学和自然科学的重大前沿领域之一,同时也将是21世纪自然科学的核心领域之一。其研究重点主要体现在基因组学(Genomics)和蛋白质组学(Proteomics)两方面,具体说就是从核酸和蛋白质序列出发,分析序列中表达的结构功能的生物信息。

SAS做的商务智能和SAP的商务智能有什么区别_sap商务智能是什么

这个问题有点大,几句解释不清,以下信息供参考:SAPBI解决方案的特点-SAP的BI战略强调协同,目标是使BI工具在企业的上中下游协同有效的工作。SAPBusinessObjects的BI产品组合是向决策层、分析和业务人员,SAP则使用在运营部门,两类产品相互补充,涵盖了BI应用的各个方面。对于BI解决方案的各个功能模块,SAP主要通过两个工具来实现:一是集数据仓库、数据挖掘和结果展示为一体的SAPBW;二是侧重于前端分析、展示和报表的BI平台——SAPBusinessObjectsXI。SAPBW是SAP在数据仓库和商务智能方面的经典产品,而SAPBusinessObjectsXI的亮点在于拥有世界一流的水晶报表和专为财务和业务分析师设计的OLAP分析引擎。二者的无缝集成进一步扩大了原有的优势。另一方面,操作型BI是SAP长期的重要技术目标,使用BI来获得ERP系统和供应链系统数据更大的分析和探索是SAP巩固其ERP市场地位,同时扩展新市场的重要战略。操作型BI可以通过SAPERP系统来实现实时地客户的绩效分析(也可以通过数据仓库一起来实现),同时支持利用开放的数据库实现商务智能分析。用户可以更容易的及时发现ERP工作流中的问题,从而实时修改、优化操作,提高操作的绩效。SASBI解决方案的特点-SAS公司的BI相关工具和扩展产品多达数十种,涵盖了BI应用的各个方面,这些工具可以相互组合成针对各行业和各种应用的BI解决方案,加上SAS在数据分析和数据挖掘上领先的技术,SAS的BI解决方案在BI的核心项目——发现海量数据中有价值的信息——方面占有绝对的优势。SAS产品的优势是产品包括报表和KPI以及其他针对专门业务需求的分析工具;能够有效地将高级分析功能嵌入到报表、仪表盘和其他应用程序中;提供了数据载入内存分析和非常好的可视化效果,以及用更多的业务分析功能。其劣势在于价格昂贵且使用难度大:许多数据处理和高级分析任务需要SAS编程语言,对缺乏相关技术的人形成了技术障碍。另外,SASBI的灵活性较差。

adf详细资料大全

ADF(Automatic Direction Finder:自动方位搜寻器)要搞清楚ADF,先要搞清 NDB(Non-Directional Beacon:无指向性无线电信标),NDB是设定于地面上之送讯装置,和ADF协同工作完成飞机的惯性导航。NDB-ADF虽然有容易安装的长处,但其缺点也有不少,例如所产生之最大误差有时会达到十度左右和会产生传送上之误差等。 基本介绍 中文名 :adf 全称 :Automatic Direction Finder 中文 :自动方位搜寻器 用于 :航空器上 基本资料,NDB-ADF的套用,NDB-ADF的缺点,ADF(自动输稿器)概述,ADF(酸性洗涤纤维)概述,其他内容,Application Development Framework,ADF检验,Oracle ADF的架构,软体所能模拟的体系的尺度,软体所属的类型,软体能研究的相关领域,软体中主要涉及的理论方法范畴,软体主要包含的处理工具,与此软体密切相关的软体, 基本资料 ADF(自动方位搜寻器)概述 NDB使用190-1750KHz带,通常只附上用1020Hz进行调幅调变的局部符号。由于NDB讯号包含有方位数据,所以航空器上若搭载ADF(Automatic Direction Finder:自动方位搜寻器),可以用RMI(Radio Magic Indicator:无线电磁指示器)显示机首方向与与地面上之角度。所以若飞行员飞行的角度为零的时候,表示正位于该地上局之正上方,NDB视有效通达距离而定可以输出20w至数kw,低电力NDB称为罗盘定位器(Compass Locator)与ILS外部记号并设运用在最终进场定点(FAF:Final Approach Fix)。NDB由于是以垂直偏波且水平面无指向性的方式来发射讯号,所以使用T型天线或垂直天线。垂面内的天线放射图示于图三。 NDB-ADF的套用 航机直线状向地面站前进时,站上的受讯讯号会极端的减少。这个锥形无声区(Cone of Silence)持有航线定点的机能,锥形无声区定点的精密度,与航机搭载天线的指向性相关联,如果搭载天线的图形,在下侧有空白(Null)存在的话,其经密度即可提高。 无线电电波方位之侧定,在送收讯点有唯一的传送路径存在时,可以获得正确数据。但实际上送收讯间的地表面是复杂的形状,所以常形成多重传送路径。利用来求取方位数据的电波是地表波,而地表波的传送距离会随地表性质(诱电率或导电率等)而改变。至于NDB有效通达距离则会受到输出、传送路径、大气杂音及空间波强度等的影响。NDB的送讯天线从使用周波数带到尺寸上都受到限制,所以天线的放射能率最高为20﹪左右。大气杂音乃因空电而产生,其杂音的程度以低纬度(赤道附近)最低。所以,为了获得相同得传达距离,在低纬度必须实施高电力输出。另外,由于空间波必须比地表波强度低15dB以上,所以这也决定有效传达距离的限界。表一为这些关系之一例。 NDB的设定较容易,其装置的价格在无线航法设施中也属最低,同时大多数的地上局也广泛套用,所以大部分的航机都已装备了ADF作为基本的导航设备。 ADF如图四所示,是由天线、自动定向接收机,RMI(磁方向指示器:Rotary Magic Indicator)及控制盒所组成。天线则是由环型天线(Loop Antenna)与辨向天线(垂直天线)(Sense Antenna)构成。能够自动探知地上传来送讯讯号(连续波、或用识别符号变调的连续波)的发出方向的动作称为ADF波形,这个时候是使用环型天线与辨向天线的讯号,如果只需接收无指向数据以及识别符号的话,就单使用辨向天线(ANT波形)。天线的安装位置是设于机体上侧或下侧约略中央处,并且将环型天线、辨向天线、以及四分圆误差补正器和增辐器等一起放入机体中运用。环型天线的方位数据讯号有45度、135度、225度、315度等。由于会产生甚大之方位误差所以利用四分圆误差补正器将误差补正至±2度以下。受讯讯号从天线上的三条讯号线传送至收讯机。此传送线讯号因为很微弱,所以为了使外部影响达到最小,必须考虑使其远离其它导体、或将表面遮覆住等问题。另外装着天线的机体表面,其接地阻抗不能太高,至于天线也必须要防卫雷电或静电放电影响。 ADF受讯周波数的选择,乃依据统括ADF控制器与航空电子学的管理系统而定,通常是190kHz至1750kHz之间以0.5kHz的间隔进行。至于受讯机的方位数据,其中仿真数据显示于RMI,而计数数据在实时点则不提供给驾驶员。 NDB-ADF的缺点 NDB-ADF虽然有容易安装的长处,但其缺点也有不少,例如下列之问题等。 (1)所产生之最大误差有时会达到十度左右。 (2)会产生传送上之误差。 方位测定上虽然是使用地上波,但是到了夜间时,由于电离层所反射的空间波会增加,所以常会造成误差。此外,打雷所伴随的空电影响也影响甚大。所以,渐渐地VOR被广泛的使用起来,并利用在罗盘定位器上。 ADF(自动输稿器)概述 ( Automatic Document Feeder 自动原稿输送器)自动输稿器,作为复印机的组成部分之一。在几年前还是很多用户认为可有可无的选购件,而现在却是很多数码复合机的标准配置。越来越多的用户认为,使用ADF可以大大节省扫描原稿的人工时间,特别是很多机器同时配备了自动翻转器后,复印双面文稿就得心应手了。 事实上,ADF只是单面输送原稿,而DADF才是双面输稿器,原稿放在DADF的托盘上(图中3)时,就已经启动了托盘上的感测器,感测器会检测出原稿的大小;按下复印键后,搓稿轮(图中1,使用时盖下)将原稿搓入一张,在进入ADF后,原稿正面以复印机稿台前部的ADF玻璃上经过,由玻璃下的曝光灯将原稿曝光,光经反光镜、镜头后进入CCD图像感测器,将光信号变为电信号存入主机板上的RAM(记忆体)中。原稿继续前进,输送到出稿托盘上(图中2),如果是单面原稿,那么扫描结束。如果是双面原稿,DADF在第一面扫描后,将原稿再次反搓入ADF内,并将原稿翻身,进行第二面的扫描,第二面扫描完成后,原稿被输送到出稿托盘上,结束运行。 DADF一般都是在大型复印机中才有的 一个功能 ADF(酸性洗涤纤维)概述 (Acid detergent fiber,酸性洗涤纤维) 植物性饲料可溶于酸性洗涤剂的部分称为酸性洗涤剂溶解物(ADS),主要有中性洗涤剂溶解物(NDS)和半纤维素,剩余的残渣称为酸性洗涤纤维(ADF),其中含有纤维素、木质素和矽酸盐,此外由中性洗涤纤维(NDF)与酸性洗涤纤维(ADF)之差即可得到饲料中的半纤维素含量。 其他内容 Application Development Framework (Application Development Framework)是Oracle公司为简化J2EE程式开发的复杂性专门开发的一种解决方案。 ADF通过减少实现设计模式和应用程式框架的代码量,简化了J2EE的研发难度。其优点主要体现在以下四个方面: (1) 开发环境:大部分J2EE框架都没有与之配套的开发工具,ORACLE为ADF提供了JDEVELOPER开发工具,它和ADF实现了完美的结合,方便了程式的开发。 (2) 平台独立:ADF能够运行在任何符合J2EE标准的套用伺服器上。 (3) 技术选择:对于应用程式的不同层,开发人员可以使用自己擅长的技术进行开发。 (4) 端到端的解决方案:ADF不只关注应用程式的某一层,而是对应用程式的每一层,都提供了完整的解决方案。 ADF检验 ADF检验(Augmented Dickey-Fuller test) 是Eviews软体中一种检查序列平稳性的单位根检验方法。ADF检验的输出结果包括检验滞后变数系数的ADF统计量和检验所需的临界值(1%,5%,10%)。如果系数显著不为零,实为小于零,那么 包含单位根的假设将被拒绝,从而接受备择假设平稳。 Oracle ADF的架构 Oracle ADF的架构是基于MVC设计模式的,其架构如图1所示。从图1我们可以看出,ADF把应用程式分成了四层,下面我们分别介绍: 1)Business Service 层 Business Service 层包括三个小层(见图1),分别是持久层(Persistent Business Objects),数据访问层(Data Aess)和接口层(ADF Application Module)。这三层建立的顺序是这样的,先建立持久层的实体对象(Entity Object),然后建立数据访问层的视图对象(ViewObject),最后建立接口层。其中建立持久层的实体对象主要是和资料库的表或者同义词对象建立关联,数据访问层的视图对象(ViewObject)是基于实体层的实体对象建立的,主要是进行资料库的访问,而接口层是整个Business Service 层和Model层的接口,在数据访问层建立的视图对象需要注册到接口层中,这样在Model层中才可以访问。 2)Model 层 该层包括两部分(见图1),分别是ADF Bindings和ADF DataControl,其中ADF Bindings是ADF提供的一种绑定技术,ADF DataControl 是指我们已经在接口层中注册的视图对象(ViewObject)。这一层在实际开发中基本不需要开发者做太多的工作。 3)Controller 层 ADF 在Controller层中扩展了APACHE基金会的STRUTS框架,它为Struts提供了一个页面流转图,以简化应用程式的开发。开发者可以简单地拖拽Struts的组件到这个图表中,这个图表会自动地同步更新Struts-config.xml档案,其中我们最常用的是DataPage组件,该组件的作用主要是建立一个页面,并且自动为其建立一个DataForwardAction,如果我们有一些自定义的方法,也可以写一个Action,然后覆盖DataForwardAction。 4)View 层 在View层可以采用ORACLE 的UIX 技术,它里面定义了大量功能强大的组件。Oracle Jdeveloper 在View 层提供了一个可视化的布局编辑器,开发者可以使用组件面板向应用程式添加可视化的组件,并可以运用属性编辑器(Property Inspector)来定义这些组件的属性。可视化的编辑器是和源码同步的,所以开发者可以选择自己喜欢的开发方式。 Amsterdam Density Functional ADF(Amsterdam Density Functional)是基于密度泛函理论(DFT)的量化计算软体。 软体所能模拟的体系的尺度 软体所能模拟的体系的尺度,如微观,介观或跨尺度等 ADF软体可计算气相、液相和蛋白质体系,并附带独立程式BAND用于处理周期性体系,如晶体、聚合物以及固体表面。ADF软体被广泛套用于许多研究领域,如催化作用、光谱性质、(生物)无机化学、重元素化学、表面性质、纳米技术和材料科学等。 ● 适于研究化学反应能垒、分子内电子结构特征以及各种波谱性质 ● 不仅可以计算气相分子,还可研究溶液环境和固体表面性质 ● 能够计算晶体、聚合物和蛋白质 ● 处理过渡金属和重元素化合物时具有独特优势 ● 支持Client-Server模式,高效快捷地提交计算和管理计算任务 ● 专业的技术团队支持,活跃的网上交流社区 ● 支持各种主流作业系统,运行速度快,计算结果精确 软体所属的类型 软体所属的类型,如MD,DPD,DFT,MC,量化,或交叉等 DFT,与其他软体相比的优点是: 使用STO基函式而不是常见的GTO来描述原子轨道,计算量由原来的O(Natom3)减少为O(Natom),对大分子体系的计算速度显著提高。 可以使用全电子基组计算周期表中的所有元素而无需引入赝势,计算结果更加精确。 能够充分套用所有分子的对称性,包括非Abelian群,从而大幅度减少对称性分子体系所需的计算时间 对于过渡金属和重元素的开壳层体系,其它量化软体往往难以收敛,而ADF一般都能正常得到结果。 计算过程中可以定义外加电场(均匀电场或点电荷电场),并提供多种溶液环境模型,包括目前套用最为广泛的FDE和COSMO模型。 独有的分子片段分析方法,用户可以将研究的体系任意划分为多个片段,详细分析各个片段之间的轨道相互作用。 提供了丰富的波谱预测手段(UV/Viz、IR、Raman、X-ray、CD、NMR、ESR等),并可以图形方式显示大部分的波谱拟合结果。 提供功能强大的图形用户界面,仅用滑鼠就可以完成非常复杂的参数设定,用户不必再面对枯燥的计算脚本,工作效率大幅度提高且不容易出错。 提供专门的任务管理界面,用于远程任务控制(提交任务、查看进度、中止计算、下载计算结果)。 提供批量任务设定与查看,对于任务类型相同的计算,批量导入三维分子结构后即可得到完成一组计算的参数设定,并在计算完成之后以表格形式对比显示各个计算任务的结果。 软体版本更新迅速,可以及时为用户提供各种最新的算法和分析手段。 软体能研究的相关领域 软体能研究的相关领域,使用者的背景最好是? 对密度泛函理论,基本量子力学有一定的理解即可。 软体中主要涉及的理论方法范畴 20世纪60年代,Hohenberg、Kohn和Sham提出密度泛函理论(DFT)。DFT理论奠定了将多电子问题转化为单电子方程的理论基础,给出了计算单电子有效势的方法。DFT在计算物理、计算化学、计算材料学等领域取得巨大成功,1998年,Kohn与分子轨道方法的奠基人Pople分享了诺贝尔化学奖。 与Hartree-Fock方法以及半经验方法相比,DFT方法可以提供更高的计算精度,并能够地处理含金属原子的分子体系。而与传统的从头算方法(MP2,CI,CC等)相比,DFT方法的优势在于它所需的硬体资源较少,计算速度快,利用目前的硬体平台能够精确处理含有数百个原子的体系(结合QM/MM方法可以处理数千个原子)。 软体主要包含的处理工具 ADF软体的可选模组包括用于处理分子体系的ADF程式和用于处理周期性结构的BAND程式,以及相应的图形用户界面ADF-GUI、BAND-GUI。ADF2008新增COSMO-RS模组,专门用于研究溶液体系的热力学性质。 与此软体密切相关的软体 ADF-GUI,Molden ADF法案:《废弃物处理预收费法》

有关圣诞节既英文故事~

更新1: 有冇英文? Plot summary The story begins by establishing that Jacob Marley Ebenezer Scrooge&#39;s business partner in &quot;Scrooge & Marley &quot; was dead—the narrative begins seven years after his death to the very day Christmas Eve. Scrooge and his clerk Bob Cratchit are at work in the counting-house with Cratchit stationed in the poorly heated &quot;tank &quot; a victim of Scrooge&#39;s stinginess. Scrooge&#39;s nephew Fred es in to wish his uncle a &quot;Merry Christmas&quot; and invite him to Christmas dinner the next day. He is di *** issed by Scrooge. Two portly gentlemen collecting charitable donations for the poor e in right after but they are rebuffed by Scrooge. At the end of the workday Scrooge grudgingly allows Cratchit to take Christmas Day off but to be all the earlier to work on the day after. Scrooge leaves the counting-house and eventually returns to his home an isolated townhouse formerly owned by his late business partner Jacob Marley. In keeping with his miserly character Scrooge lives in a *** all suite of largely unfurnished rooms within the house which he keeps dark and cold. While he unlocks his door Scrooge is startled to see the ghostly face of Marley instead of the familiar appearance of his door knocker. Marley has e to warn Scrooge that his miserliness and contempt for others will subject him to the same fate Marley himself suffers in death condemned to walk the earth in penitence since he had not done it in life in concern for mankind. A prominent symbol of Marley&#39;s torture is a heavy chain wound round his form that has attached to it symbolic objects from Marley&#39;s life fashioned out of heavy metal: ledgers money boxes keys and the like. Marley explains that Scrooge&#39;s fate might be worse than his because Scrooge&#39;s chain was as long and as heavy as Marley&#39;s seven Christmases ago when Marley died and Scrooge has been adding to his with his selfish life. Marley tells Scrooge that he has a chance to escape this fate through the visitation of three more spirits that will appear one by one. Scrooge is shaken but not entirely convinced that the foregoing wasn&#39;t a hallucination and goes to bed thinking that a good night&#39;s sleep will make him feel better. At one o&#39;clock in the morning the first spirit appears and introduces himself to Scrooge as The Ghost of Christmas Past. This spirit leads Scrooge on a journey into some of happiest and saddest moments of Scrooge&#39;s past. These include the mistreatment of Scrooge by his uncaring father the loss of a great love sacrificed for his devotion to business and the death of his sister the only other person who ever showed love and passion for him. Visions provided by the second spirit The Ghost of Christmas Present show him the meagre Christmas celebrations of the Cratchit family the sweet nature of their crippled son Tiny Tim and a possible early death for the child; this prospect is the immediate catalyst for his change of heart. They also show the faith of Scrooge&#39;s nephew in his uncle&#39;s potential for change a concept that slowly warms Scrooge to the idea that he can reinvent himself. The visit of the third spirit The Ghost of Christmas Yet to Come a grim spectre much more frightening that the other spirits harrows Scrooge with visions of the Cratchit family bereft of Tiny Tim of Scrooge&#39;s own lonely death and final torment and the cold avaricious reactions of the people around him after his passing. Without explicitly being said Scrooge can avoid his own fate and that of Tiny Tim – but only if he changes.

荒岛余生 课本原文

In the movie Cast away,Tom Hanks plays a man named Chuck Noland.Chuck is a businessman who is always so busy that he has little time for his friends.He is a successful manager in a company that sends mail all over the world.One day Chuck is on a flingt across the Pacific Ocean when suddenly his plane crashes.Chuck survives the crash and lands on a deserted island. On the island,Chuck has to learn to survive all alone.He has to learn how to collect water,hunt for food, and make a fire.Perhaps the most difficult challenge is how to survive without friends.In order to survive, Chuck develops a friendship with an unusual friend--a volleyball he calls Wilson. Chuck learns a lot about himself when he is alone on the island.He realises that he hasn"t been a very good friend friend because he has always been thinking about himself.During his five years on the island,Chuck learns how to be a good friend to Wilson.Even though Wilson is just a volleyball,he becomes fond of him.He talks to him and treats him as a friend.Chuck learns that we need friends to share happiness and sorrow,and that it is important to have someone to care about.He also learns that he should have cared more about his friends.When he makes friends with Wilson,he understands that friendship is about feelings and that we must give as much as we talk. A volleyball is certainly an unusual friend.Most of our friends are human beings,but we also make friends with animals and even things.For example,many of us have pets,and we all have favourite objects such as a lucky pen or a diary.The lesson we can learn from Chuck and all the others who have unusual friends is that friends are teachers. Friendship helps us understand who we are,why we need each other and what we can de for each other. 希望你能用上 我也是在网上找的其实大部分的资料网上都是有的

ArcGIS可以安装在哪些运行环境

从应用的角度,地理信息系统由硬件、软件、数据、人员和方法五部分组成。硬件和软件为地理信息系统建设提供环境;数据是GIS的重要内容;方法为GIS建设提供解决方案;人员是系统建设中的关键和能动性因素,直接影响和协调其它几个组成部分。 硬件主要包括计算机和网络设备,存储设备,数据输入,显示和输出的外围设备等等。 软件主要包括以下几类:操作系统软件 、数据库管理软件 、系统开发软件 、GIS 软件,等等。 GIS软件的选型,直接影响其它软件的选择,影响系统解决方案,也影响着系统建设周期和效益。 数据是GIS的重要内容,也是GIS系统的灵魂和生命。数据组织和处理是GIS应用系统建设中的关键环节,涉及许多问题: ——应该选择何种(或哪些)比例尺的数据? ——已有数据现势性如何? ——数据精度是否能满足要求? ——数据格式是否能被已有的GIS软件集成? ——应采用何种方法进行处理和集成? ——采用何种方法进行数据的更新和维护,等等。 方法指系统需要采用何种技术路线,采用何种解决方案来实现系统目标。方法的采用会直接影响系统性能,影响系统的可用性和可维护性。 人是GIS系统的能动部分。人员的技术水平和组织管理能力是决定系统建设成败的重要因素。系统人员按不同分工有项目经理、项目开发人员、项目数据人员、系统文档撰写和系统测试人员等。各个部分齐心协力、分工协作是GIS系统成功建设的重要保证。 GIS应用系统建设需要从以上五个方面着手。GIS 的应用领域 地理信息系统在最近的30多年内取得了惊人的发展,广泛应用于资源调查、环境评估、灾害预测、国土管理、城市规划、邮电通讯、交通运输、军事公安、水利电力、公共设施管理、农林牧业、统计、商业金融等几乎所有领域。 (加测绘、应急、石油石化等国民经济各个领域。) 以下地理信息系统的应用领域分别回答了在各自领域内的作用 ◆ 资源管理 (Resource Management) 主要应用于农业和林业领域,解决农业和林业领域各种资源(如土地、森林、草场)分布、分级、统计、制图等问题。主要回答“定位”和“模式”两类问题。 ◆ 资源配置 (Resource Configuration) 在城市中各种公用设施、救灾减灾中物资的分配、全国范围内能源保障、粮食供应等到机构的在各地的配置等都是资源配置问题。GIS在这类应用中的目标是保证资源的最合理配置和发挥最大效益。 ◆ 城市规划和管理 (Urban Planning and Management) 空间规划是GIS的一个重要应用领域,城市规划和管理是其中的主要内容。例如,在大规模城市基础设施建设中如何保证绿地的比例和合理分布、如何保证学校、公共设施、运动场所、服务设施等能够有最大的服务面(城市资源配置问题)等。 ◆ 土地信息系统和地籍管理 (Land Information System and Cadastral Applicaiton) 土地和地籍管理涉及土地使用性质变化、地块轮廓变化、地籍权属关系变化等许多内容,借助GIS技术可以高效、高质量地完成这些工作。 ◆ 生态、环境管理与模拟 (Environmental Management and Modeling) 区域生态规划、环境现状评价、环境影响评价、污染物削减分配的决策支持、环境与区域可持续发展的决策支持、环保设施的管理、环境规划等。 ◆ 应急响应 (Emergency Response) 解决在发生洪水、战争、核事故等重大自然或人为灾害时,如何安排最佳的人员撤离路线、并配备相应的运输和保障设施的问题。 ◆ 地学研究与应用 (Application in GeoScience) 地形分析、流域分析、土地利用研究、经济地理研究、空间决策支持、空间统计分析、制图等都可以借助地理信息系统工具完成。 ◆ 商业与市场 (Business and Marketing) 商业设施的建立充分考虑其市场潜力。例如大型商场的建立如果不考虑其他商场的分布、待建区周围居民区的分布和人数,建成之后就可能无法达到预期的市场和服务面。有时甚至商场销售的品种和市场定位都必须与待建区的人口结构(年 龄构成、性别构成、文化水平)、消费水平等结合起来考虑。地理信息系统的空间分析和数据库功能可以解决这些问题。房地产开发和销售过程中也可以利用GIS功能进行决策和分析。 ◆ 基础设施管理 (Facilities Management) 城市的地上地下基础设施(电信、自来水、道路交通、天然气管线、排污设施、 电力设施等)广泛分布于城市的各个角落、且这些设施明显具有地理参照特征的。它们的管理、统计、汇总都可以借助GIS完成,而且可以大大提高工作效率。 ◆ 选址分析 (Site Selecting Analysis) 根据区域地理环境的特点,综合考虑资源配置、市场潜力、交通条件、地形特征、环境影响等因素,在区域范围内选择最佳位置,是GIS的一个典型应用领域,充分体现了GIS的空间分析功能。 ◆ 网络分析 (Newwork System Analysis) 建立交通网络、地下管线网络等的计算机模型,研究交通流量、进行交通规则、处理地下管线突发事件(爆管、断路)等应急处理。 警务和医疗救护的路径优选、车辆导航等也是GIS网络分析应用的实例。 ◆ 可视化应用 (Visualization Application) 以数字地形模型为基础,建立城市、区域、或大型建筑工程、著名风景名胜区的三维可视化模型,实现多角度浏览,可广泛应用于宣传、城市和区域规划、大型工程管理和仿真、旅游等领域。 ◆ 分布式地理信息应用 (Distributed Geographic Information Application) 随着网络和Internet技术的发展,运行于Intranet或Internet环境下的地理信息系统应用类型,其目标是实现地理信息的分布式存储和信息共享,以及远程空间导航等。GIS常用软件 国外的: AutoCAD Map3d ArcGIS(包括ArcGIS, MapObjects, ArcIMS、ArcSDE、ArcEngine、ArcServer等) MapInfo GeoMedia MGE SmallWorld Grass 国内的: Supermap MapGIS GeoStar TopMap GeoBean VRMap MapEngine geobrain

这个是好东西,收集纪念了!一.控制面板-》服务-》MS SQL SERVER-》登陆--》本地系统帐户--》重新启动MS SQL SERVER用windows验证登陆查询分析器--》执行 sp_password null,sa新密码,"sa"二."无法连接到服务器,用户xxx登陆失败"该错误产生的原因是由于SQL Server使用了"仅 Windows"的身份验证方式,因此用户无法使用SQL Server的登录帐户(如 sa )进行连接.解决方法如下所示:1.在服务器端使用企业管理器,并且选择"使用 Windows 身份验证"连接上 SQL Server操作步骤:在企业管理器中--右键你的服务器实例(就是那个有绿色图标的)--编辑SQL Server注册属性--选择"使用windows身份验证"--选择"使用SQL Server身份验证"--登录名输入:sa,密码输入sa的密码--确定2.设置允许SQL Server身份登录操作步骤:在企业管理器中--展开"SQL Server组",鼠标右键点击SQL Server服务器的名称--选择"属性"--再选择"安全性"选项卡--在"身份验证"下,选择"SQL Server和 Windows ".--确定,并重新启动SQL Server服务.在以上解决方法中,如果在第 1 步中使用"使用 Windows 身份验证"连接 SQL Server 失败,那就通过修改注册表来解决此问题:1.点击"开始"-"运行",输入regedit,回车进入注册表编辑器2.依次展开注册表项,浏览到以下注册表键:[HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSSQLServerMSSQLServer]3.在屏幕右方找到名称"LoginMode",双击编辑双字节值4.将原值从1改为2,点击"确定"5.关闭注册表编辑器6.重新启动SQL Server服务.此时,用户可以成功地使用sa在企业管理器中新建SQL Server注册,但是仍然无法使用Windows身份验证模式来连接SQL Server.这是因为在 SQL Server 中有两个缺省的登录帐户:BUILTINAdministrators<机器名>Administrator 被删除.要恢复这两个帐户,可以使用以下的方法:1.打开企业管理器,展开服务器组,然后展开服务器2.展开"安全性",右击"登录",然后单击"新建登录"3.在"名称"框中,输入 BUILTINAdministrators4.在"服务器角色"选项卡中,选择"System Administrators"5.点击"确定"退出6.使用同样方法添加 <机器名>Administrator 登录.说明:以下注册表键:HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSSQLServerMSSQLServerLoginMode的值决定了SQL Server将采取何种身份验证模式.1.表示使用"Windows 身份验证"模式2.表示使用混合模式(Windows 身份验证和 SQL Server 身份验证).
