The definition of a schedule assumes that operations can be totally orderedby time. Consider a database system that runs on a system with multiple processors,where it is not always possible to establish an exact ordering betweenoperations that executed on different processors. However, operations on adata item can be totally ordered.Does this situation cause any problem for the definition of conflict serializability?Explain your answer.

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.
