SharePoint 2010 – Business Connectivity Services (BCS)

In this article we can explore another feature of SharePoint 2010 – Business Connectivity Services.  This service allows data reading and writing from external data sources.

Using BCS we can access and modify data from:

·  WCF Service
·  Database
·  Business Applications
·  .Net Assembly connecting to Business Data
·  Custom Connectors

BCS Architecture


The BDC Runtime is responsible for connecting to the external data sources.  External data sources connections are stored in BCS Metadata inside SharePoint.  The BCS Metadata allows connecting to the data sources in offline mode too.  SharePoint acts as a Presentation layer in this scenario.




Note


The previous version of BCS was BDC (Business Data Catalog)

Following are the components of BCS.
 
 
BDC Metadata Store

This component provides storage for metadata consisting of external data sources and content types and it will be part of the BCS layer.

BDC Server Runtime


This runtime component is responsible for connecting to the BDC Metadata Store and processing the requests.

BDC Client Runtime


Client runtime providing offline storage, synchronizing data back to server etc.

SharePoint Designer


We can use SharePoint Designer provided tools for creating BCS Solutions.
