TAILIEUCHUNG - Thủ thuật Sharepoint 2010 part 02

Ứng dụng dịch vụ Ngoài ra thú vị khác là ứng dụng dịch vụ SharePoint. Nếu bạn đã sử dụng MOSS 2007, sau đó bạn có thể quen với dịch vụ chia sẻ kiến trúc của nó (SSP) cung cấp. Các SSP là một dịch vụ trung tâm là chia sẻ nguồn tài nguyên chung với một hoặc nhiều ứng dụng web. Điều này cho phép SharePoint để thực hiện một trong thu thập dữ liệu, ví dụ, nhưng cung cấp các chức năng tìm kiếm cho tất cả các ứng dụng web trong trang trại mà không nhân đôi nỗ. | Service Applications 7 FIGURE 1-3 SERVICE APPLICATIONS Another exciting addition to SharePoint is Service Applications. If you have used MOSS 2007 then you may be familiar with its Shared Service Provider SSP architecture. The SSP was a central service that shared common resources with one or many web applications.
