Abstract
Database systems and computer network make easy distribution of data into the geographical dispersed locations. Distribution of data at network nodes enables us to sustain data availability, reliability and achieve performance. A continuous effort were given by researcher with the passage of time to cope-up with existing design weaknesses and seems to be a challenging task due to expandable behavior of the network, continuous redesign of existing distributed system to entertain queries of different nature from different users. To implement distributed system a sequential process of fragmentation, allocation and replication of data is required. In a distributed transactional environment getting relevant data and satisfying query responses are the key issues. So, appropriate ramification in the existing approaches is required to overcome distributed data distribution challenges. In my propose paper, it is to focus on highlighting different challenges of fragmentation, allocation and replication in distributed environment with their countermeasures to resolve it.
