Abstract
Information systems (data tables) are often used to represent experimental data [4],[5],[8]. In [16] it has been pointed out that notions of extension and restriction of information system are crucial for solving different class of problems [6],[7],[10]-[11],[12]-[15]. The intent of this paper is to present some properties of an information system extension (restriction) and methods of their verification.
