Business intelligence development studio enhances the development of business intelligence applications because you can work on analysis services projects in a source - controlled , multi - user environment without requiring an active connection to an analysis services instance Business intelligence development studio增强了商业智能应用程序的开发，原因是您可以在源代码管理的多用户环境中处理analysis services项目，而不需要与analysis services实例建立活动连接。
It is found ecn could n ' t solve the problem that the sender responds to congestion slowly , and the average queue length of router is sensitive to the static parameters of ecn . in chapter four we propose an algorithm called fecn , which provides congestion control and indication messages in router , so that the sender could response to congestion in good time . this algorithm can also adjust the max drop probability according to the active conne Ik的特性，而且平均队列长度和网络吞吐量对ecn的静态参数较为敏感，因此本文在第4章中提出了一种fecn算法，该算法在路山器处提供拥塞控制和指示机制，使源端能够快速响应路由器发回的拥塞指示消息，调整发送速率，避兔拥塞的发生，该算法还可以通过估计链路中的活动连接数动态调整最大丢弃概率。
Users running ole db applications need a connection for each open connection object , users running open database connectivity odbc applications need a connection for each active connection handle in the application , and users running db - library applications need one connection for each process started that calls the db - library 对于运行ole db应用程序的用户，每个打开的连接对象需要一个连接；对于运行开放式数据库连接( odbc )应用程序的用户，每个活动连接句柄需要一个连接；对于运行db - library应用程序的用户，每个调用db - library
It combined into the loose datum visiting demand , multi - layer web application program and web service as well as expand function of ado . through supporting the visiting to loose coupling of the data , ado . net has reduced the active connecting figure with activity of the data base ( reduce the possibility of a lot of user ' s competence to the limited resource of database server ) , thus reached the share at the maxium degree 它扩展ado的功能，并且支持结合松散的数据访问需求、多层web应用程序及web服务。通过支持对数据的松耦合访问， ado . net减少了与数据库的活动连接数目(即减少了多个用户争用数据库服务器上的有限资源的可能性) ，从而实现了最大程度的数据共享。
