Subject Re: cross posting white paper pointer - "Oracle Berkeley DB Java Edition vs Apache Derby: A Performance Comparison"
Date Thu, 30 Nov 2006 05:51:25 GMT
I read the paper and it seemed like an apples to oranges comparison. It 
sounded like comparison of
some proprietary API  to JDBC ?

Also could not find details about how exactly the timings were measured 
(JDBC PreparedStatement v/s some put(key,data) API  ?).

Anyways, here is another paper from them comparing Berkeley DB with 
Relational database systems in general.

This one seemed more relevant since Berkeley DB is essential touted as a 
library and not a full-fledged database system.

Also should you get a chance try reading the licensing terms ( I got a 
bit lost reading their FAQ):
