Is it possible to fully ensure transaction independence by excluding any interactions between them in a database management system?

It is practically impossible and impractical to fully ensure transaction independence by eliminating any interactions between them. In database management systems (DBMS), transactions often compete for the same resources (e.g., data), so synchronization and isolation mechanisms are necessary.

Levels of transaction isolation (e.g., Read Committed, Repeatable Read, Serializable) are used to manage interactions, balancing performance and data consistency. Complete independence (Serializable level) provides maximum isolation but reduces concurrency and performance.

Thus, interactions between transactions are not completely eliminated but are controlled to ensure the correctness and efficiency of the system.
