Peer-to-Peer (P2P) systems share and manage huge amounts of data and resources distributed across a large number of machines. In pure P2P environments the control is totally decentralized in peers, which are autonomous, perform the same roles and do not have a global view of the entire system. Several P2P solutions have been deployed and proposed in literature managing data within a single P2P system with a variety of different features and performances. But in all cases a single P2P system conceptually corresponds to a single database containing a unique relational table and all functions, such as querying, routing and content location, are defined to properly work just within such a single system. Existing solutions cannot support several databases, which originate and grow separately, or simply just one database with several tables, because it would be necessary many distinct P2P systems. In this paper we present a solution to merge G-Grid P2P systems, which are multi-dimensional di...
