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.

Question

By storing data in a temporary location, buffers help speed up data transfers
between various layers of a computer's memory system. In the above
architecture, please detail any buffers that may exist between the L1 and L2
caches, and between the L2 cache and the RAM.

Expert Solution

Step 1

Between the L1 and L2 cache, buffers are required.

The buffer required between the L1 cache and the L2 cache is the write buffer.

The purpose of this write buffer is to decrease access latency.

If there is a miss on the L1 cache, the data may be retrieved via the L2 cache.
