QCE Digital Solutions Unit 2: Validation, security and data management processes
Students check data with validation and verification, then protect and manage it using encryption, searching, pattern recognition and de-identification.
One content description from the full QCE Digital Solutions Unit 2 — Data and Programming Techniques journey. All 21 modules below are in that journey too, with the same content — add just these to a class, or the whole strand.
