❷ 什么是MS sql 2000, ColdFusion, .NET, UML, JavaScript/AJAX, CSS/DHTML, 它们的关系
sql是MS出的大型数据库，coldfusion是adobe公司的一个功能强大的应用开发平台，.net是MS出的web开发平台,js是sun公司的，css/dhtml是网页的格式类型，CSS是指用来定义网页样式的一种言语，现在特流行
你问的这些基本都是web方面应用的
❸ 怎么把STAR UML 导入 SQL
你要看他有没有反向工程功能，能不能支持模型导入sql，比如trufun plato建模工具有支持正向工程的框架，也有支持数据库建模，支持将数据库表反向生成数据库模型，也可以将数据库模型正向生成数据库表和视图！
❹ 输入SQL Server原代码，就可以生成UML类图，其他的UML图也可以。急呀，请告知。
不能够用源代码生成UNL的类图,不过可以在SQL Server中已有的表进行生成的，使用工具PowerDesigner来生成就行,有关PowerDesigner的资料你可以去网上找找,有很多的
❺ SQL SERVER数据库报824错误怎么解决
Hi黑暗ㄨ吠，
824错误，也就是所谓的软IO错误，可以理解为SQL Server已经读取到该页，但通过计算CheckSum等值发现不匹配，因此SQL Server认为该页已经被损坏。此错误与错误 823 类似，只是 Windows 不检测这一错误。这通常表明 I/O 子系统中存在问题，例如磁盘驱动器存在故障、磁盘固件存在问题、设备驱动程序不正确等等。查找硬件故障运行硬件诊断以解决任何问题。也可以通过检查 Microsoft Windows 系统和应用程序日志以及 SQL Server 错误日志以查看是否存在由硬件故障引起的错误。解决这些日志中包含的所有与硬件相关的问题。如果存在持久性数据损坏问题，请尝试改用其他的硬件组件来解决此问题。进行检查以确保系统未启用磁盘控制器上的写缓存。如果您怀疑是写缓存出现问题，请与硬件供应商联系。最后，您可能会发现，切换到全新的硬件系统是解决问题的极佳途径。此切换操作可能包括格式化磁盘驱动器和重新安装操作系统。如果出现的问题与硬件无关，并且已知的干净备份可用，则请从备份中还原数据库。考虑将数据库改为使用 PAGE_VERIFY CHECKSUM 选项。
另外你也可以通过用WINHEX分析SQL Server文件的结构并更正，再DBCC检查

❼ UML是什么，包括哪些内容
解释：
1、 UML -----The Unified Modeling Language is a standard language for writing software blueprints.The UML may be used to visualize, specify, construct, and document the artifacts of a software-intensive system.
2、 Stereotype-----A stereotype is an extension of the vocabulary of the UML, allowing you to create new kinds of building blocks similar to existing ones but specific to your problem.
3、 Tagged value-------A taffed value is a property of a stereotype, allowing you to create new information in an element bearing that stereotype.
4、 Component--------A component is a replaceable part of a system that conforms to and provides the realization of a set of interfaces.
5、 Message-----A message is the specification of a communication among objects that conveys information with the expectation that activity will ensure
6、 Note-----A note is a graphical symbol for rendering constraints or comments attached to an element or a collection of elements.
7、 Constraints------A constraint is a textual specification of the semantics of a UML element, allowing you to add new rules or to midify existing ones.
8、 Interaction-----An interaction is a behavior that comprises a set of messages exchanged among objects in a set of roles within a context to accomplish a purpose.
9、 Action----An action is an executable computation that results in a change in state of the model or the return of a value.
简答
1， UML中描述软件体系结构的五种视图及其内容？architecture view
@The use case view of a system encompasses the use cases that describe the behavior of the system as seen by its end users,analysts,and testers.
@The design view of a system encompasses the classes,interfaces,and collaorations that from the vocabulary of the problem and its solution.
@The interaction view of a system shows the flow of control among its various parts,including possible concurrency and synchronization mechanisems.
@The implementation view of a system encompasses the artifacts that are used to assemble and release the physical system.
@The deployment view of a system encompasses the nodes that form the system`s hardware topology on which the system executes.
2， 建模的四项基本原则？principles of modeling
*The choice of what models to create has a profound influence on how a problem is attached and how a solution is shaped.
*Every model may be expressed at different levels of precision.
*The best models are connected to reality.
*No single model or view is sufficient.Every nontrivial system is best approached through a small set of nearly independent models with multipe viewpoints.
3，如何建模系统的接缝？modeling the seams in a system
To model the seams in a system:
!!Within the collection of classes and components in your system,draw a line around those that tend to be tightly coupled relative to other sets of classes and components.
!!Refine your grouping by considering the impact of change,
. Classes or components that tend to change together should be grouped together as collaborations.
!!Consider the operations and the signals that cross these boundaries, from instances of one set of classes or components to instances of other sets of classes and components.
!!Package logically related sets of these poerations and signals as interfaces.
!!For each such collabotation in your system,identify the interfaces it requires from(imports) and those it provides to others(exports).You model the importing of interfaces by dependency relationships,and you model the exporting of interfaces by realization relationships.
!!For each such interface in your system,document its dynamics by using pre-and postcongitions for each operation, and use cases and state machines for the interfaces as a whole.
4.如何建模系统的需求？modeling the requirements of a system
To model the requirements of a system:
//Establish the context of the system by identifying the actors that surround it;
//For each actor,consider the behavior that each expects or requires the system to privide;
//Name common behaviors as use cases.
//Factor common behavior into new use cases that are used by others;factor variant behavior into new use cases that extend more main line flows.
//Model these use cases,actors,and their relationships in a use case diagram;
//Adorn these use cases with notes or constraints that assert nonfunctional;you may have to attach some of these to the whole system.
5如何利用制品图建模物理数据库？modeling a physical database by artifact diagrams
1. For simple CRUD(create, read, update,delete) operations,implement them with standard SQL or ODBC calls;
2. For more-complex behavior(such as business rules), map them to triggers or stored proceres.
Guidelines:
&Identify the classes in your model that represent your logical database schema.
&Select a strategy for mapping these classes to tables.You will also want to consider the physical distribution or your databases.Your mapping strategy will be affected by the location in which you want yout data to live on your deployed system.
&To visualize,specify,construct,and document your mapping,create an artifact diagram that contains artifacts stereotyped as tables.
&Where possible,use tools to help you transform your logical design into a physical design.
6如何对注释建模？modeling comments
*Put your comments as text in a note and place it adjacent to the element to which it refers. You can show a more explicit relationship by connecting a note to its elements using a dependency relationship.
*Remember that you can hide or make visible the elements of your model as you see fit.This means that you don`t have to which it is attached are visible.Rather,expose your comments in your diagram only insofar as you need to communicate that information in that context.
*If your comment is lengthy or involes something richer than plain text,consider putting your comment in an external document and linking or embedding that document in a note attached to your model.
*As your model evolves,keep those comments that record significant decisions that cannot be inferred from the model itself,and-unless they are of historic interest-discardthe others.
7，如何建模逻辑数据库模式？modeling a logical database schema
The UML`s class diagrams are a superset of entity-relationship(E-R) diagrams, a common modeling tool for logical database design.
To model a schema:
$Identify those classes in your model whose state must transcend the lifetime of their applications.
$Create a class diagram that contains these classes.You can difine your own set of stereotypes and tagged values to address database-specific details.
$Expand the structural details of these classes.In general,this means spencifying the details of their attributes and focusing on the associations and their multiplicities that relate these classes.
$Watch for common patterns that complicate physical database design,such as cyclic association and one-to-one associations.Where necessary,create intermediate abstractions to simplify your logical structure.
$Consider also the behavior of these classes by expanding operations that are important for data access and data integrity.In general,to provide a better sepatration of concerns,business rules concerned with the manipulation of sets of these objects should be encapsulated in a layer above these persistent classes.
$Where possible,use tools to help you transform your logical design into a physical design.
8，给出顺序图的步骤？modeling flows of control by time ordering
To model a flow of control by time dodering:
+Set the context for the interaction,whether it is a system, subsystems,operations,or class,or one scenario of a use case or collabotation;
+Set the stage for the interantion by identifying which objects play a role in the interaction.Lay then out on the sequence diagram from left to right,placing the more important objects to the left and their neighboring objects to the right;
+Set the lifeline for each object.In most cases,objects will persist through the entire interaction. For those objects that are created and destroyed ring the interaction ,set their lifelines,as appropritate,and explicitly indicate their birth and death with appropriately stereotyped messages;
+Starting with the message that initiates this interaction, lay out each subsequent message from top to bottom between the lifelines,showing each message`s properties, as necessary to explain the semantics of the interaction;
+If you need to visualize the nesting of messages or the points in time when actual computation is taking place, adorn each object`s lifeline with its focus of control;
+If you need to specify this flow of control more formally, attach pre-and postconditions to each message.
9，如何利用制品图建模可执行程序的发布？modeling an executable release
To model an executable release:
#Identify the set of artifacts you`d like to model.Typically,this will involve some or all the artifacts that live on one node,or the distribution of these sets of artifacts across all the nodes in the system.
#Consider the stereotype of each artifact in this set.For most systems you`ll find a small number of different kinds of artifacts.You can use the UNL`s extensibility mechanisms to provide visual cues for these stereotypes.
#For each artifact in this set, consider its relationship to its neighbors.Most often,this will involve interfaces that are exported by certain artifacts and then imported by others.If you want to expose the seams in your system,model these interfaces explicity.If you want your model at a higher level of abstraction, elide these relationships by showing only dependencies among the artifacts.
❽ 什么是时态数据库、和传统数据库有什么不一样还有中间件和UML，谁能简要介绍下
区别于传统的关系型数据库(RDBMS)，时态数据库(Temporal Database)主要用于记录那些随着时间而变化的值的历史，而这些历史值对应用领域而言又 时态数据库是重要的，这类应用有：金融、保险、预订系统、决策支持系统等。
目前时态数据库还没有像如Oracle、SQL Server等大型关系数据库那样的产品。在当前时态数据库技术尚未完全成熟的现状下，DBMS提供商不会轻易把时态处理功能引入现有的DBMS中，因此，利用成熟的RDBMS数据库，建立时态数据库的中间件，在现阶段是一个较好的选择，因此就应运而生TimeDB和TempDB了。
中间件是一种独立的系统软件或服务程序，分布式应用软件借助这种软件在不同的技术之间共享资源。中间件位于客户机/ 服务器的操作系统之上，管理计算机资源和网络通讯。是连接两个独立应用程序或独立系统的软件。相连接的系统，即使它们具有不同的接口，但通过中间件相互之间仍能交换信息。执行中间件的一个关键途径是信息传递。通过中间件，应用程序可以工作于多平台或 OS 环境。
可扩展标记语言 (Extensible Markup Language, XML) ，用于标记电子文件使其具有结构性的标记语言，可以用来标记数据、定义数据类型，是一种允许用户对自己的标记语言进行定义的源语言。 XML是标准通用标记语言 (SGML) 的子集，非常适合 Web 传输。XML 提供统一的方法来描述和交换独立于应用程序或供应商的结构化数据。
❾ 各位老师：UML是什么，主要是干什么用的请简单说明
UML统一建模语言，哎，这么写的话根本不知道是什么吧
我举个例子吧，sql
uml跟sql一样，是一种语言，它是用来建模的（实体、用例等），使用在设计领域的
而我们通常说的uml指的是uml工具
比如visio里可以建uml工程，rose可以建uml工程等等，很多工具都能（就像oracle，sql server都能建数据库，用sql语言访问）
❿ UML的类图可以转换成SQL吗
从用例图过渡到类图，用例图一般是分析项目功能的，类图是项目实现。
从用例图到类图，没有直接的转换关系，一般都是根据开发经验。
