Hello, I'm a Ph D student. My dissertation (Agronomy area) is about the = importance of relational databases (RDBMS) as a source of structured information for several = aspects at the agricultural engineering level. One of the points that I = would like to study is the link between a RDBMS and DSSAT models. In the last days I have been practising with DSSAT software. One of the = first conclusions of that "hands-on" is that DSSAT software would be = must more friendly if, at most for the novice (those like my self...), = there is a underlying RDBMS. I would be very pleased with some answers about this topic. Thank you very much for your time. Carlos P. Caldeira Note: I am using LUIS MIRA DA SILVA copy of DSSAT software.
