How you map Java objects to relational tables determines the efficiency of the generated SQL queries. Poor mapping choices lead to unnecessary joins and data redundancy. Identifier Generation Share public link This foundation then moves into

Essential when data contention is high and conflicts are costly (e.g., financial transactions, inventory reservation). It issues a SELECT ... FOR UPDATE statement, blocking other transactions from modifying or reading the target rows until the current transaction commits. 5. Advanced Database Tuning for Java Developers
