Users of the Wev services is increasing by the diffusion of smartphone and tablet pc.
However it caused the webserver down.
Therefore, scalability is the important software factor for Web services today.
Scalability in distributed system is able to increase performance linearly when just added new node to system.
In order to provide scalability to Web services, database must have scalability.

For study of scalable database, we are designing and developing a database Jungle which has non-destructive tree structure.
Non-destructive tree structure dose not destruct the data when data editing by creating new tree.

In this paper, we implemented persistent and distributed database on jungle.
Distributed data on Jungle is developed by using Alice which is parallel distributed framework.
We confirm the data distribution between the server nodes on Jungle with our cluster system.
Also, we developed simple bulletinboard system with Jungle and key-value store database Cassandra.
We compared response time of Jungle and Cassandra using simple bulletinboard.
As a result, Jungle got better performance than Cassandra.
