Quality Perception in Information Systems
The quality of information is usually perceived by accessing multiple objects, namely
- Hardware (e.g. a computer),
- Application (e.g. query software, web browsers, search engines, etc.),
- Schema / Ontology (i.e. the structure in which the data is stored), and
- Data itself
In order to find the root cause of information quality problems, it is important to be aware about the above layers. E.g. performace issues regarding data access may often be referred to insufficient configuration of the application or lack of hardware performance.
