Hardware malfunctions, such as disk crashes
Natural disasters, such as fires and floods
There are many ways to minimize these threats to data integrity. These include:
Backing updata regularly
Controlling access to data via security mechanisms
Designing user interfacesthat prevent the input of invalid data
Using error detection and correction software when transmitting data
