If we apply a distributed version of the multiple-granularity protocol of Chapter 18 to a distributed database, the site responsible for the root of the DAG may become a bottleneck. Suppose we modify that protocol as follows:• Only intention-mode locks are allowed on the root.• All transactions are given the strongest intention-mode lock (IX) on theroot automatically.Show that thesemodifications alleviate this problem without allowing any nonserializable schedules.

Types of database architectures

A Database Architecture represents the Database Management System’s (DBMS) design (schema). The DBMS architecture makes it easy to understand the components involved in the database system and their relations. The DBMS architecture may vary based on the system on which it runs. Some systems contain both client and server machines whereas some run only on a server machine. Based on the architecture, the system can be classified as centralized, decentralized, or hierarchical.
