Final answer:
Concurrency Control is critical in systems with concurrent processes to prevent data inconsistencies and preserve database transaction integrity.
Step-by-step explanation:
Concurrency Control is needed to address the Concurrency Control Summary Problem in databases and other systems where multiple processes or users access and manipulate data concurrently. Without adequate concurrency control mechanisms, several issues can arise, such as lost updates, temporary inconsistency, and permanent inconsistency of data. These problems are significant in systems where data integrity is critical; therefore, implementing robust concurrency control strategies is essential to ensure that the system functions correctly and reliably. Concurrency control ensures that database transactions are performed in a secure and consistent manner, preserving the ACID (Atomicity, Consistency, Isolation, Durability) properties of transactions.
