[[Image:MKDE model.svg|right|241px|thumb|The MKDE model allows for different database backends to be plugged into Pervasive's software product.]]
Starting with version 6.15, Pervasive started using a new modular method of separating the database [[Back-end database|backend]] from the interface that developers used. They separated the core database operations (like update, write and delete records) from the Btrieve and [[Scalable SQL]] modules. By separating the Micro-Kernel Database Engine (MKDE) from the other functions it allowed [[programmer]]s to use several methods of accessing the database simultaneously. For instance, an application may be created using the Btrieve [[API]] and another [[Application software|application]] that needs to access the same data may use a totally different method, like using Scalable SQL. Because the [[Record (computer science)|record]] primitives have been separated from these methods, both applications can use the MKDE to access the same data [[Computer file|file]].

The Micro-Kernel Database Engine is unrelated to [[microkernel]] operating system kernels.
