- What does a stable database state entail, and how is it accomplished? The DBMS makes no promise that the transaction's symbolic sense accurately reflects the underlying real-world event. What are the potential ramifications of that restriction? Give an illustration. What does the term "serializable transactions" mean?arrow_forwardDiscuss the various architectural models of Distributed DBMS, such as client-server, peer-to-peer, and hybrid models. Provide examples of scenarios where each model is suitable.arrow_forwardWhat does a stable database state include, and how is it attained?
