Concurrency control is a database management technique that ensures transactions are executed in a safe and consistent manner, even when multiple transactions occur simultaneously. It prevents conflicts and maintains data integrity by managing the interaction between concurrent transactions, ensuring that the system remains reliable and efficient.

Transactions are fundamental units of work in databases and financial systems, ensuring data integrity and consistency through a sequence of operations that are treated as a single logical unit. They follow the ACID properties—Atomicity, Consistency, Isolation, and Durability—to ensure that even in the event of a system failure, data remains accurate and reliable.

Conflicts happen when people or groups don’t agree on something, and it can make them feel upset or angry. Solving conflicts is important because it helps everyone feel better and makes sure everyone can play or work together happily.

Data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle, ensuring that it remains unaltered and trustworthy for decision-making and analysis. It is crucial for maintaining the credibility of databases and information systems, and involves various practices and technologies to prevent unauthorized access or corruption.
