The Layer2 Business Data List Connector for SharePoint 2007, 2010 and 2013 connects almost any external data source to native SharePoint lists (e.g. contacts, tasks, events, news or custom lists) codeless and in just minutes with ALL list features available - even change notifications and workflows. It simplifies your SharePoint architecture and solves many issues that still exist with SharePoint out-of-the-box data integration. Version 4 now comes with additional data providers to support CSOM (SharePoint 2010/2013, SharePoint Online, Office 365), File System (for SharePoint library replication), XML/RSS (files and web requests) and OData (e.g. Microsoft ERP/CRM) as external sources.
