Relational data structure of the coating database from the "Coatings & High Temperature Corrosion Data Bank"

Abstract
A data bank on coatings and high temperature corrosion, called C[MATH]HTC-DATA, has been created and will be operated by the Corrosion Data Centre at the University of Provence in Marseille - France. This data bank has been created to help to choose coatings for specific applications, knowing their fabrication process characteristics and their protectivity characteristics. C&HTC-DATA will include five databases, viz. 1) a bibliographic reference data base, 2) a coatings database, 3) a corrosion database, 4) an alloy composition database, and 5) a directory of addresses of companies and researchers involved in the field of high temperature corrosion and protection of materials. Four of these databases have been installed by the ORACLE Relational Data Base Management System (R.D.B.M.S.) and are in the β stage of "on line" operation. In this paper the relational structure of the factual data on coatings in the coating database is discussed.
