I am working on a project in which i need to consolidate 2 or more decision tree generated by J48 algorithm.

full scenario is as follows:

- My work is in distributed data mining.
- Students educational record is being used for evolution purpose.
- there are 4 server and 4 dataset[huge].
- J48 algorithm is applied to all datasets.
- Individual decision tree is generated at each server accordingly.
- All decision tree are fetched at middleware to consolidate these trees to form a global decision tree.
- Generated global tree will sent to all server.
- when any query comes, it will divided into 4 numbers of equal file and process at each server which contains global decision tree.
- result from all server will fetched to middleware and global result will be generated.
