What Is Business Connectivity Services?<br />

BCS bridges the gap between various applications that a company uses and the company’s<br />

need to surface key business data from those applications into SharePoint. These<br />

applications can include Siebel, CRM, and SAP, and the data from the applications needs<br />

to appear in SharePoint sites, lists, search functions, and user profiles. In the context of<br />

BCS, these applications are known as external systems. By using BCS, a company can accomplish<br />

the following objectives:<br />

●●<br />

●●<br />

●●<br />

●●<br />

Reduce or eliminate the code required to access line-of-business (LOB) systems.<br />

Achieve deeper integration of data in places where a user works.<br />

Centralize deployment of connection definitions for use by both BCS and Office<br />

applications. This capability is a major advantage of BCS over the connection methods<br />

described in Chapter 6, “Working with Data Sources,” where each site owner<br />

needs to acquire connection details of the external system data.<br />

Reduce latency to access and manipulate data. Once an external system is defined<br />

in BCS, the connection definition is available in all site collections in Web applications<br />

within the same service application group. Then, in the browser, data from the<br />

external systems can be presented by using the XSLT List View (XLV) Web Part on<br />

Web pages and business data columns in lists and libraries. On SharePoint Server<br />

Enterprise edition, the Business Data Web Parts are available to present data from<br />

the external systems. In addition, users who can use SharePoint Designer on their<br />

sites can create a DFWP. Both an XLV Web Part and a DFWP can be used to create<br />

views or data entry forms that can create, read, update, and display (CRUD) data<br />

from the external systems.
