What types of data integrity and reliability guarantees are provided when working with a database?

When working with a database, the following types of data integrity and reliability guarantees are provided:

• Atomicity: operations within a transaction are executed completely or not at all.
• Consistency: after a transaction is completed, the database remains in a correct state, satisfying all constraints and rules.
• Isolation: parallel transactions do not affect each other, and the result is equivalent to sequential execution.
• Durability: after a transaction is committed, changes are saved and not lost even in case of failures.

These properties are known as ACID and form the basis of reliable data management.

Additionally, databases ensure:

• Data integrity through constraints (e.g., uniqueness, foreign keys).
• Recovery after failures using transaction logs and backups.

In Go, when working with databases, drivers and ORMs are typically used, which support transactions and allow managing these guarantees.
