The outline of JICST factual database (JOIS-F), which JICST has started from January, 1988, and its online service are described in this paper. First, the author mentions the circumstances from 1973, when its planning was started, to the present, and its relation to "Project by Special Coordination Founds for Promoting Science and Technology". Secondly, databases, which are now under development aiming to start its services from fiscal 1988 or fiscal 1989, of DNA, metallic material intensity, crystal structure, chemical substance regulations, and so forth, are described. Lastly, its online service is briefly explained.

The computer programme, which builds atom-bond connection tables from nomenclatures, is developed. Chemical substances with their nomenclature and varieties of trivial names or experimental code numbers are inputted. The chemical structures of the database are stereospecifically stored and are able to be searched and displayed according to stereochemistry. Source data are from laws and regulations of Japan, RTECS of US and so on. The database plays a central role within the integrated fact database service of JICST and makes interrelational retrieval possible.

This paper describes the system outline, characteristics and use of JICST Thermophysical and Thermochemical Properties Database of which service was started as one part of JICST Factual Database System. This system enables to store data of more than 60 kinds of physical or chemical thermal properties. It covers elements, pure substances of inorganic and low molecular organic compounds, and two or three component systems of these compounds. The system is designed to enable to deal with floating decimal point numerical data identifying significant figures, to provide versatile searching supports, and to link its searching to other databases. The actual use examples and some points to be careful are also described.

JICST Mass Spectral Database which had started from March, 1987 made a fresh start at January, 1988 as JOIS-F (JICST Online Information System-Fact) including two other JICST Factual Databases. Renewal point of it are data up-dated, a new function of cross-retrieval and a small change of command. The outline of data items, retrieval system and availability are given again.

In considering the relationship of informationization and industrial structure, this paper analize some factors such as information revolution, informationization of industries and industrialization of information as background of informationization of Japanese society. Next, some information indicators such as, information coefficient of household which is a share of information related expenditure, information coefficient of industry which is a share of information related cost to total cost of production, and information transmission census developed by Ministry of Post and Telecommunication are introduced. Then new information indicator by Economic Planning Agency, that is, electronic info-communication indicator is showed. In this study, the information activities are defined to produce message or to supply services on process, stores or sale of message using electronic information equipment. International comparisons of information labor force are also presented.
