A Concurrency Control Protocol for Clipping Indexing project is a cse project which is implemented using java and Mysql. 

This project explains about analyzing the situation in multidimensional databases and its growth in various applications and improvements need to be done to satisfy present growth.

In this paper we propose a effective concurrency control protocol which is integrated to R+ tree for supporting fast access to multidimensional data. 

But this new mechanism is not possible to directly apply to R+tree because object in R+tree may be indexed in multiple levels.

In order to solve this problem, we use granular locking for clipping indexing. This is the first method which is specially designed for R+ trees.
