# Management of Bank Accounts

The management of bank accounts are a demanding task which has used database systems as aid for some time. Today, it is unthinkable to operate in the very complex world of finances without the help of database systems.
The most important characteristics of such database systems:

Transaction | The successfull and correct course of transactions is very important when managing bank accounts. It cannot be true that a credit is made to the wrong account or that a debit is made more than once.

Data Integrity | Data integrity is very important. It needs to be clearly defined what the requirements and rules of consistency are and how these can be followed.

Data Persistence | For an owner of a bank account it is reassuring to know that the persistence of the data is guaranteed. Data are not deleted arbitrarily or are lost mysteriously.
