This section details a selection of advanced features of the Microsoft Excel Online driver.

User Defined Views

The driver supports the use of user defined views, virtual tables whose contents are decided by a pre-configured user defined query. These views are useful when you cannot directly control queries being issued to the drivers. For an overview of creating and configuring custom views, see User Defined Views .

SSL Configuration

Use SSL Configuration to adjust how driver handles TLS/SSL certificate negotiations. You can choose from various certificate formats;. For further information, see the SSLServerCert property under "Connection String Options" .

Firewall and Proxy

Configure the driver for compliance with Firewall and Proxy, including Windows proxies and HTTP proxies. You can also set up tunnel connections.

JDBC Remoting

Configure JDBC Remoting to connect to the driver from remote machines. You can choose between remoting via CLI and using a configuration file.

Caching Data

Caching Data enables faster access to data and reduces the number of API calls, improving performance. The connector supports a simple caching model where multiple connections can also share the cache over time. When configuring the cache connection, you can specify automatic or explicit data caching.

Query Processing

The driver offloads as much of the SELECT statement processing as possible to Microsoft Excel Online and then processes the rest of the query in memory (client-side).

For further information, see Query Processing.

Logging

For an overview of configuration settings that can be used to refine CData logging, see Logging. Only two connection properties are required for basic logging, but there are numerous features that support more refined logging, which enables you to use the LogModules connection property to specify subsets of information to be logged.
