Question

Law in IT

Good afternoon!
What should be considered ISPD - a separate Database where PD is stored, or all software where they can be stored?
For example, personal data can be scattered in different 1C products (accounting, payroll and personnel, ERP, CRM), on several sites and the processing goals are different for everyone. It turns out that the organization has several ISPDs?

Answer 1

type one, containing this is all

Answer 2

An information system is called a system because it can include different elements and subsystems ... it’s all of you who describe in the PD policy what (what software) it consists of, how it receives, uses and stores PD, etc. ...
