Since early 90s of 20th century has seen a steady and dynamic growth databases and collected information. There has also been a steady increase in demand for information, on the other hand growth in collection and storage information. One of the properties of some databases is their dynamic, changing during the group structure. The article presents an overview of the basic concepts of dynamic grouping and its proposed new definition. It was also a practical method to implement dynamic grouping based on self-learning neural network type of GNG. The results of simulation studies are presented in a dynamic grouping.
