The paper is devoted to the problem of the need to improve the efficiency of intervalvalued data processing in computers, complexes and computer networks and to reduce the
time of its creation; search for methods to improve the reliability of the application software,
the means of unifying its development. Interval-valued data library has been developed in
order to solve these tasks. It implements a user-defined interval-valued type and basic
operations on it which makes it possible to reuse a reliable and efficient data type which
performs integrity checks in databases by default, removing this task from an application
programmer, providing to operate with the boundaries of the intervals as with single objects
speeding up the software development when organizing interval data bases and requesting to
analytical processing. Solutions to support interval data types in database systems allow to
solve a wide class of data analysis tasks operating with interval data, in particular, the
clusterization of cast iron problem in the industrial reference information-analytical system.
