The Layer2 Business Data List Connector for SharePoint makes it as easy as possible to connect native SharePoint lists to almost any external data source, codeless and bi-directional. The app closes many issues and overcomes limitations that still exist with SharePoint out-of-the-box data integration today.
To configure simply:
1. Enter connection string
2. Enter select statement
3. Enter primary keys.
Fast background updates (changed data only) via timer job. Alerts and workflows can be used to take business actions in SharePoint, when external data records are changed. Optionally write-back changes to data source.
