Database and DBMS basics – UGC NET Question

Statements A, B and C correctly describe what databases and DBMSs do in ICT systems. They highlight that databases store structured data, DBMSs manage and control access to it and relational models use tables with rows and columns. Statement D is clearly false because a DBMS is software, not a hardware cupboard for printed documents. Thus the combination A, B and C only is correct.

Option A:
Option A is incorrect because it includes only A and B and omits C. While A and B are true, statement C is also correct in describing relational storage structures. Leaving out C means the option does not capture all the valid statements.

Option B:
Option B is incorrect because it groups A, B and D as correct, thereby accepting D. Statement D completely misrepresents a DBMS, so any combination that treats it as true is invalid.

Option C:
Option C is incorrect because it lists B and C only and leaves out A. Statement A is fundamental in defining a database as an organised collection of data. Excluding this definition makes the combination incomplete.

Option D:
Option D is correct because it selects A, B and C, all of which align with standard database concepts. It correctly excludes D, which confuses software with physical storage and printed documents.
