It seems me that Oracle DB will be able to reach this term.
May be in the future some of todays large DB servers like Oracle, MS SQL Server, MySQL and DB2 will continue live and will have backward compatibility.
But according me every 10 years you client should update and to implement newer technologies, keeping main DB structure.
