Benefits of OLEDB Integration with SharePoint


  • Very easy to setup in a few minutes: Create a SharePoint list, click "Connect to external data source" in the list settings, select the data provider, enter connection settings and data query as shown below. That's it.
  • No changes in the OLEDB data source: No programming, no additional tools.
  • Connected data always up-to-date: The connected OLEDB data updates automatically in background (via SharePoint Timer Job), or alternatively, on-demand (Action Menu / Ribbon Button, URL, via workflow, API).
  • One-way and optional two-way connection: You can write-back the changes made in SharePoint to the external OLEDB data source automatically with full CRUD (Create / Update / Delete) functionality. The SharePoint list can act as a full-featured front-end for external systems.
  • Well-known BCS external list issues and limitations are completely solved: ALL list features are to you. Views, sorting and grouping, filters, calculated fields, search, managed metadata. Lookups, additional columns and attachments can be created as normal. All kind of lists can be used, e.g. contacts, tasks, calendar, or custom lists. You can take external data offline via Outlook.
  • Workflows and notifications on external data change: List workflows and change notifications per RSS or email can be used to take business actions in SharePoint, when external OLEDB data records are changed.
  • Application logging, reporting, and notifications: A SharePoint list is used to store settings and log information. SharePoint item versioning and workflows can be used to manage reporting and notifications. Direct notification per email in case of errors is supported as well.
  • Highest Security, best performance, easy to maintain: SharePoint Secure Store can be used to store security relevant configuration information safely in one central place. Users are working with the SharePoint lists as an external data cache with highest security and performance.
  • 100+ external systems supported: Layer2 Data Providers included (e.g. for SharePoint/Office 365, Exchange, Dynamics, OData, XML/RSS, SOAP), vendor specific data providers can be used (e.g. SQL Server Oracle, mySQL etc.), 3rd party data providers also supported, e.g. for ERP/CRMs, Facebook or Twitter.

  • Please enter an appropriate primary key (column with unique values), depending on query (see data preview for this).
  • You can use the connection for uni- or bi-directional synchronization.
  • No installation or changes are required at the ODBC data source or data destination.
