Current DBMSs all seem to be using B+ Trees, but AVL Databases are quicker on solid state storage. Is there a DBMS that can plug Applied Calculus into its back end.
I checked out Enterprise DBMS on the internet. It seems that that is a classification rather than an actual product. All the databases they mentioned there were B+ Trees. It seems that nobody is doing AVL Trees. AVL Trees speed up by a factor of 20 on Solid State Drives.
Perhaps AVL Databases don't need a DBMS. You access the services of an AVL Database directly at the source code level. The databases are highly stable and don't really require any form of managment.
