About Data integrity

What is the difference between ALCOA AND ALCOAPLUS

Data integrity is the degree to which data are complete, consistent, accurate, trustworthy,
reliable and that these characteristics of the data are maintained throughout the data life cycle.
The data should be collected and maintained in a secure manner, so that they are attributable,
legible, contemporaneously recorded, original (or a true copy) and accurate. Assuring data
integrity requires appropriate quality and risk management systems, including adherence to
sound scientific principles and good documentation practices.

Data should be: (Following ALCOA principles)
A - attributable to the person generating the data
L – legible and permanent
C – contemporaneous
O – original record (or certified true copy)
A - accurate
Data governance measures should also ensure that data is complete, consistent, enduring
and available throughout the lifecycle, This is ALCOA Plus+
Complete – the data must be whole; a complete set
Consistent - the data must be self-consistent
Enduring – durable; lasting throughout the data lifecycle
Available – readily available for review or inspection purposes
Hope you have understood the concept.
