Object-oriented databases are still struggling to gain a foothold in corporate data management. One of the problems has been reconciling the object model with the relational model. David Linthicum discusses this problem in "Objects Meet Data" (www.dbmsmag.com/9609d16.html), and includes a list of object-to-relational products and vendors. A comprehensive list of object-oriented CASE tools from the July 1997 issue of DBMS Online can be found at www.dbmsmag.com/9707d161.html.
