Realisation of Object-Oriented 'SPRAVOCHNIC' (Extended Dictionary) by Means of Documental Information System 'IRIS'

An hystohierarchial object-oriented database model, 'SPRAVOCHNIC' (extended dictionary), is presented, which was realised on the base of the documental information system 'IRIS'. It provides an integration of office databases into common information fond for some application environments. The information funds of the dictionary include the integrated data about objects, that must be defined previously. 'Spravochnic' allows to build multihierarchies on objects, to look through all the modification of objects and to construct the search-tree upon the object database with names of hierarchies, types of dependencies, time of modification of objects and times of actuality of the values of atributes taken as parameters.
