A company stores its customer data using a database managed by a Database Management System (DBMS). A new employee needs read-only access to customer records but must not be able to modify or delete any data. Which feature of the DBMS is used to enforce this restriction?

Q: How do I try a free CIE Computer Science question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Computer Science bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Computer Science students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Computer Science questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Computer Science syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A company stores its customer data using a database managed by a Database Management System (DBMS). A new employee needs read-only access to customer records but must not be able to modify or delete any data. Which feature of the DBMS is used to enforce this restriction?

Accepted Answer

Access rights — Award 1 mark for Access rights. Access rights (also called user privileges) within a DBMS allow the system administrator to grant different levels of permission — such as read-only, read/write, or full control — to different users. Data validation (C) checks that data entered meets defined rules (e.g. range checks), but does not restrict user permissions. A is incorrect — data encryption protects data from unauthorised external access by encoding it, but does not manage internal user permission levels. B is incorrect — backup scheduling ensures data can be recovered after loss, but does not control what individual users can do with data.
