On-Line Information Systems for the Environmental Sciences

On-line systems are available to assist engineers and scientists in the retrieval and acquisition of technical information. This paper reviews the on-line data bases and related information services in the environmental sciences. The different types of data bases (bibliographic, numeric, and full text), the information they contain, and their potential value to researchers are described.

A data-base system as a decision-taking aid in a cardiologic environment

A software package is presented for the set up and management of archives of the definite population for clinical use. The archives accept both numeric data and free text. The package runs on a minicomputer system to allow the access to Data Base technology by small clinical groups. Besides the read/write facilities the system is oriented toward the extraction of user suggested and defined subsets of the population and their analysis.The Data structure has been defined so as to:—discharge the data-entry operator from non-relevant procedures and to maximize his performance.—leave the Data Base manager free to modify easily the previously defined data base and to up-grade with new not previously accepted variables.—accept data from direct recordings from the patient via automatic instrumentation.The system has been applied to a few different populations with related cardiovascular problems such as:(a) data from coronary arteriography, ventriculography, and other special cardiac examinations.(b) data from pa...
