The Mimer Provider Manager allows an application to transparently access ADO.NET
providers. The application is isolated from the specifics of different
providers. It allows an identical application to access several underlying
ADO.NET providers with no or minimal changes to the application.
The benefits of this architecture are the following:
Independent on underlying provider used.
Easy to switch to another provider.
Possible to pick the highest performance configuration without any application
Not locked into a specific database.
Allows concurrent access to different providers.
The interfaces supported are the standard interfaces for accessing ADO.NET
providers. This means that applications that use the Mimer Provider Manager by
default does not use ADO.NET provider specific features. However, the
architecture allows the applications to also access provider specific features.
This is done in a manner that makes it clear that this is happening. So, for
example, an application may consist of 98% provider independent code and 2%
provider specific. When using the Mimer Provider Manager the 2% are easily
