Office 365 SharePoint Integration and Synchronization
Office 365, SharePoint, and OneDrive for Business can be integrated and synchronized codelessly with various other data sources using the Layer2 Cloud Connector via the Layer2 Data Provider for
SharePoint (CSOM), bi-directionally if required. While structured data
like database queries can be synchronized with native SharePoint lists,
unstructured data - for example a file share - can be synchronized with
SharePoint libraries. Please take a look here for supported systems and applications.
