What are the disadvantages of banks using databases?

Banks using databases face several disadvantages, including the risk of data breaches that can expose sensitive customer information. Additionally, maintaining and securing large databases can be costly and complex, requiring significant resources and expertise. There is also the challenge of data integrity and accuracy, as errors or inconsistencies can lead to financial losses and regulatory issues. Lastly, reliance on technology may result in operational disruptions if systems fail or if there are issues with data migration.
