Intellectual Rollback

---

Thanks to LeoBase journal of changes there is a unique possibility of intellectual rollback.Here is an example. There were several incorrect changes in a large network done by unreliable client. This was discovered too late. This changes should be cancelled without disturbing what was done by others, if it's possible. The standard rollback will lead to annulling not only his actions but also changes of other users. The intellectual rollback allows to avoid it, and that's the purpose of this rollback. The actions cancelling is complete except points which threaten the database wholeness. For example, there are situations when a record was added by mistake, by it was already reffered to by other clients. In such cases a special trigger is called. It can be overloaded, and the input data can be interpreted by programmer.
