Investigation of gas media spectroscopy at high temperature is accompanied by large and complex data amount. In order to manage these data one should use specialized information systems able to execute formal stale operations with friendly interface. In the present paper we discuss the problems of development of an integral distributed information system using up-to-date object oriented technologies and technologies for distributed systems based on CORBA 2.0 (Common Object Request Broker Architecture). On the basis of modern information technologies we have developed HOTGAS and SMOLA software. Both can be run under Windows operation system. HOTGAS is intended for calculation of spectral line parameters (SLP) and absorption coefficients for CO, CO2 and H2O in 250 - 3000 K temperature range. SMOLA is intended for accumulation, systematization and use of published SLP data for different molecules. It also has a graphic interface and possesses the advantages of other Windows software. To provide comprehensive informational support and to execute all the diversity of tasks in the sphere of rovibrational spectroscopy of gas media we offer a project for integral distributed informational system design.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
