Abstract
In one aspect, a computerized method for managing consistency and availability tradeoffs in a real-time operational database management system (DBMS) includes the step of implementing consistency in an AP mode of the real-time operational DBMS by implementing the following steps. The method adds a set of schemes that enable a real-time operational DBMS to linearize read/write operations in all situations except a first specified situation and a second specified situation. The real-time operational DBMS is in AP mode, at least one master node for every data item is available in the database cluster of the real-time operational DBMS at all times. The method implements a CP mode of operation.
