Databases are used in banking applications to store and process financial transactions; from keeping track of customer accounts, balances and deposits, to asset management, loans, and credit cards. Banking websites and mobile apps use databases to store content, customer login information and preferences and may also store saved user input.. Databases allow data to be stored quickly and easily and are used by banks in their front, middle, and back office operations. As banks continue their digital transformation efforts, migrate to the cloud, and adopt new technologies, the choice of database type and vendors is becoming increasingly critical.
