It is the middleware layer for NOSQL which guarantees full ACID properties for multi-item transactions. The architecture describes that each LTM (Local Transaction Managers) has the replica of its query to the other LTM’s, to support ACID guarantees it works on 2-Phase Commit protocol (2PC) so that if all the LTM’s commits the transactions successfully then its coordinator will complete the transactions else it will aborted the transactions. For the simple consistent read operations the query read directly in the cloud data service without referring the LTMs. Table 1 shows some key differences between cloud data services
