How to Use a Microsoft Access Database to Update XML Data in Real Time

Update XML data by creating a linked table in Microsoft Access with the CData XML ODBC Driver.

CData ODBC drivers connect your data to any database management tool that supports Open Database Connectivity (ODBC). This includes many of the most popular productivity tools, adding new capabilities for document sharing and collaboration. Using the CData ODBC driver for XML, you can update live XML data in Microsoft Access; for example, you can make updates that can be immediately seen by other users.

Connect to XML as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Connecting to Local or Cloud-Stored (Box, Google Drive, Amazon S3, SharePoint) XML Files

CData Drivers let you work with XML files stored locally and stored in cloud storage services like Box, Amazon S3, Google Drive, or SharePoint, right where they are.

Setting connection properties for local files

Set the URI property to local folder path.

Setting connection properties for files stored in Amazon S3

To connect to XML file(s) within Amazon S3, set the URI property to the URI of the Bucket and Folder where the intended XML files exist. In addition, at least set these properties:

  • AWSAccessKey: AWS Access Key (username)
  • AWSSecretKey: AWS Secret Key

Setting connection properties for files stored in Box

To connect to XML file(s) within Box, set the URI property to the URI of the folder that includes the intended XML file(s). Use the OAuth authentication method to connect to Box.

Dropbox

To connect to XML file(s) within Dropbox, set the URI proprerty to the URI of the folder that includes the intended XML file(s). Use the OAuth authentication method to connect to Dropbox. Either User Account or Service Account can be used to authenticate.

SharePoint Online (SOAP)

To connect to XML file(s) within SharePoint with SOAP Schema, set the URI proprerty to the URI of the document library that includes the intended XML file. Set User, Password, and StorageBaseURL.

SharePoint Online REST

To connect to XML file(s) within SharePoint with REST Schema, set the URI proprerty to the URI of the document library that includes the intended XML file. StorageBaseURL is optional. If not set, the driver will use the root drive. OAuth is used to authenticate.

Google Drive

To connect to XML file(s) within Google Drive, set the URI property to the URI of the folder that includes the intended XML file(s). Use the OAuth authentication method to connect and set InitiateOAuth to GETANDREFRESH.

The property is the controlling property over how your data is represented into tables and toggles the following basic configurations.

  • Document (default): Model a top-level, document view of your XML data. The data provider returns nested elements as aggregates of data.
  • FlattenedDocuments: Implicitly join nested documents and their parents into a single table.
  • Relational: Return individual, related tables from hierarchical data. The tables contain a primary key and a foreign key that links to the parent document.

See the Modeling XML Data chapter for more information on configuring the relational representation. You will also find the sample data used in the following examples. The data includes entries for people, the cars they own, and various maintenance services performed on those cars.

Create a Linked Table to people Data

Follow the steps below to create a linked table, which enables you to access live people data.

  1. On the External Data tab in Access, click ODBC Database. ๐Ÿ‘ Use the Get External Data wizard to work with ODBC data sources in Access.
  2. Select the option to link to the data source. A linked table will enable you to read from and write data to the people table. ๐Ÿ‘ Linked Tables enable you use the live connection to XML that is provided by the driver.
  3. Select the CData XML data source from the Machine Data Source tab.

    ๐Ÿ‘ DSNs listed in the Get External Data wizard.
  4. Select the people table. For more information on this table, see the "Data Model" chapter in the help documentation. ๐Ÿ‘ Available tables. (Google is shown.)
  5. Double-click the linked table to make edits. The linked table will always have up-to-date data and any changes will be reflected back to the underlying table.

    ๐Ÿ‘ A linked table to the live data. (Google is shown.)

XML ODBC Driver

The XML ODBC Driver is a powerful tool that allows you to connect with live XML data stores, directly from any applications that support ODBC connectivity.

Access XML data like you would any standard database - read, write, and update etc. through a standard ODBC Driver interface.
