If you use SQL Server Authentication login, its greatest advantage is that it is easy to achieve through the Enterprise Manager, the biggest drawback is that SQL Server Authentication login is only valid for a specific server, that is, in a multi-server environment is more difficult to manage . SQL Server authentication using a second important drawback is that, for each database, we have administrative rights for it separately. If a user on the two databases have the same permission requirements, we have to manually set permissions for the two databases, or write a script to set permissions. If the small number of users, such as 25 below, and these changes in the users permission is not very frequent, SQL Server Authentication login may apply. However, in almost all other cases, the administrative burden of this login will be more than its advantages. Even the best security policy is often the case in a prior submission, this situation is to use SQL Server Web application data. In this case, the typical method is to validate a set of SQL Server login name and password embedded in the Web server, running programs, such as the ASP page or CGI script; then verified by the Web server is responsible for the user, the application is used It is your own login account for users to access data.
Nvidia Jen-Hsun Huang, president and CEO, said the new card will help PC should come out in 2007 many of the graphics processing power applications with high requirements, including Windows Vista Aero graphical operating system technology, high-definition video, DirectX10 API. Nvidias general manager, Desktop Business Modise explained that the computer graphics requires a series of processing steps. Basic step is to draw the outline of an image graphics chip, and then outline the part of the graph coloring. The problem with this is that for the vertex shader and pixel shader circuit number is fixed. Some graphics have complex shapes, but the color is relatively simple, while awaiting completion of the vertex shader, pixel shader is responsible for the circuit is idle. Nvidia unified architecture allows the processor to GPU pixel shader is responsible for the original part of the circuit to help complete the process of vertex coloring. This will greatly improve the configuration of the PC GeForce 8800 graphics card performance.
