And these are that real obstacle, in so many cases. A relational model is also an obstacle to the building of a distributed non-standard multiple interface multiple dispatch nightmare :-) As Ole-Hjalmar has explained, a relational database is middle ground, you have something standardised with wich others can work, too. Imagine IDL and proxies as an alternative. Data exists, but which part of the ORBA application takes care maintaining its existence? Incidentally, SETL2, a set language, is said to have a tranparent database backend (proprietary), so data exists. Also between program runs. -- Georg
