The general data resources refer to the database systems that assembled data during the early stages of information processing (Oracle, SQL Server, DB2, etc.), and the dedicated data resources to geographic data, medical images (X-ray film, MRI and CT scans, etc.), and multimedia whose processing is by dedicated equipment or software. In this regard the term “sensitive” is purely descriptive; whether a data resource is sensitive or publicly available must fit criteria guided by law.
