What is "Business Connectivity Services" A Beginner View
In this article, we will learn what is Business Connectivity Services, take a look at its key features, and some of the common usage scenarios.
What is "Business Connectivity Services" - Provides read/write access to external data within Microsoft SharePoint 2010 - Replaces BDC in the previous version.
Here is a short description of some of the new features - Provides read/write access to external data within Microsoft SharePoint 2010 - Write-back to external systems - In addition to view access to data, BCS allows write-back to external systems, thus providing true external system integration. To enable write-back or data updates, the external system must support the operations and must be modeled appropriately. - Online as well as Offline data access - End-user Ease-of-use and training curve - The end users can access features and data from multiple systems thus limiting the number of systems that need to be learned. Users can focus on a single point of access using familiar UI. - Extensible Provider Model: Provides an extensible model allowing developers to plug-in connectors for a new external system type - Batch and Bulk operation Support - Reads multiple items in a single call, thus reducing roundtrips to the backend and improving performance. - Blobs, Complex types - Blob data support added. Complex types supported using the dot notation. - Abstraction - allows developers to use an abstract entity model - the same application can be used to target different external systems that use the same entity model
Here are some scenarios describing where BCS can be used: The obvious applications of BCS are in the integration with external systems into SharePoint applications. Examples include integration with databases, web/WCF Services, .Net Connection assemblies, Custom data sources - any external LOB system, in general. Another interesting scenario is the use of BCS in providing a common integration portal among different entry points. Eg. Using common standards, multiple vendor systems can be set up to feed into the Vendor Management System application for order status and invoices. Upgrade systems - SharePoint applications can be set up as the common face of an application that is expected to be upgraded/stabilized/replaced in the future. The common UI can be maintained and the backend LOB system can be replaced. Offline Data Access - A Sales LOB System can be exposed to a SharePoint application via BCS. Users can make use of the Offline Data Access feature to enter data offline and synchronize the data back when they are online.
