Berkeley DB Family

Hi,
I am currently working on a project for my masters degree. I have a large distributed system in which several thousand applications are regularly publishing messages to a few tens of servers. These messages can be any data structure and all of them have an associated time stamp. I have to be ready to accommodate for any general data structure but most of them are numeric values, strings or arrays of numbers.
The servers keep these messages in RAM and then dispose of them. What I have to do is archive the messages in databases so that later someone can use a tool to see plots of how the system behaved over time in the past, aggregate data etc
Is Berkely DB a viable option for my project? Where could I get more information to help me make up my mind about this?

Thank you,
Alex
