Modern situation in information systems design from the aspect of domain-specific languages implementation and using is discussed. Today there are several ways of integrating DSL into information system. Firstly all these methods differ in DSL type being used: internal or external, API-like or fully integrated. If all these methods are analyzed to find out all their disadvantages those ones will help to state problems which can occur while using textual DSL in information system. Such analysis will make possible to formulate research tasks which after solving will help to create new more efficient method of implemention and integration DSL into information system.
