- JOIN
- A physical backup containing every data file
- A lock that limits access to selected rows
- An index containing only unique values
- A named query that presents data like a virtual table
- It stores a reference that must point to a row in another table.
- It uniquely identifies each row and cannot contain NULL values.
- It automatically sorts the table's rows on disk.

DBMS Quiz - Description and methodology of the test
Students, early-career developers, and professionals revisiting database fundamentals can use the dbms quiz to check how confidently they reason about common relational problems. The result points toward concepts that feel secure and those needing targeted review. It is useful before coursework, while refreshing SQL practice, or when planning a focused study session. Its broad coverage makes it a practical database fundamentals quiz for turning uncertainty into specific revision goals.
What This Assessment Measures
This assessment focuses on applied DBMS knowledge rather than isolated vocabulary. Its situations ask readers to model relationships, reduce redundancy, choose SQL clauses, and distinguish transaction guarantees from concurrency failures. It suits learners reviewing database fundamentals or checking which topic needs more practice.
The result is a DBMS Knowledge score from 0-16: Foundations to build (0-6), Developing knowledge (7-12), or Strong knowledge (13-16). As a DBMS knowledge assessment, it shows how consistently a respondent applies foundational principles across connected topics.
The main thematic groups are:
- Relational design examines whether you can represent many-to-many relationships and preserve clear table links.
- Normalization checks whether you can recognize dependencies and reduce repeated facts.
- SQL querying tests joins, grouping, filtering, aggregation, and index use.
- Transactions and reliability cover ACID properties, locking, isolation anomalies, constraints, and recovery logs.
Methodology and Evidence Base
Each item uses four-option multiple choice. The respondent selects the best answer for a database situation, such as choosing a junction table, identifying a dirty read, or selecting HAVING for an aggregate condition. Distractors represent technical mistakes, so success depends on applying principles rather than recognizing terms.
Scoring combines responses into the displayed result. No separate weighting, partial-credit, or penalty scheme is stated, so the outcome is a broad snapshot across tested topics rather than a fine-grained profile. Used as a relational database quiz, it is most helpful when missed concepts lead to targeted review.
The content is conceptually consistent with Database System Concepts (Silberschatz et al., 2020), Elmasri and Navathe’s coverage of schemas, normalization, SQL, transactions, and recovery, and Codd’s relational model. These works support the principles represented in the questions; this online questionnaire is not presented as an adaptation or restandardization of any one published instrument.
The result has no population norms or reported reliability estimates. Performance can shift with recent study, wording familiarity, and how confidently a respondent interprets each scenario. It is a formative self-check, not certification.
