What are the main causes of database inconsistency?
Database inconsistency can arise from various factors, including concurrent updates, hardware failures, and software bugs.
Can you explain how concurrent updates lead to inconsistency?
Sure! When multiple transactions are executed simultaneously without proper isolation, they can overwrite each other's changes, leading to inconsistent data.
What role does data integrity play in preventing inconsistency?
Data integrity ensures accuracy and consistency of data over its lifecycle, using constraints and validation rules to prevent errors.
Are there specific strategies to avoid these inconsistencies?
Yes, strategies include using transactions, implementing locking mechanisms, and regularly auditing data for discrepancies.
