+Recently, Smartphone and tablet pc are widely used, thereby Web services that handle large amounts of data are emerging.
+It has caused the webserver is down.
+Therefore, scalability is important software factor today.
+Scalability in distributed system is able to increase performance linearly when just added new node to system.
+In order to make provide scalability, we considered design of architecture.
+
+We are developing database Jungle. 
+It is use non-destructive tree structure.
+Non-destructive tree structure is not the destruction of data.
+Editing of data is done creating by new tree.
+Jungle was designed as a distributed database.
+But data distribution and persistent has not yet been implemented in the Jungle.
+
+In this paper, we develop distributed database on jungle for pursuit architecture with scalability.
+Distributed data on Jungle is developing using parallel distributed framework Alice.
+As a result, we confirmed that data is distributed  between the server node.
