Conception and administration design of database support of web service for thermodynamic calculations

The contribution deals with proposal of conception and structure of two cooperating databases - preparatory and operating - for purposes of administration of database infrastructure of web service designed for thermodynamic calculations. The substances´ data structure is in the both databases the same. Operating database directly supports web service operation. Preparatory database attends to creation, charging, check, correction and copying of correct data into operating database. The paper specifies both databases structures, web service´s data model, sources and ways of data acquisition into preparatory database and for more detail specifies check and copy processes of particular data from preparatory to operating database. These processes are controlled by means of for this purpose created substance´s table, that contents for each substance list of error states.
