Databasespørsmål

Databasespørsmål is a Norwegian term for questions about database systems. It is used in education, exams, interviews, and professional assessments to test knowledge of data storage, retrieval, and management. The phrase can refer to prompts, tasks, or problems that participants must answer or solve, often focusing on how databases are designed, implemented, and maintained.

Typical topics include data models (relational, document, key-value), database design and normalization, SQL and querying, transactions and ACID properties, indexing and performance tuning, data integrity and constraints, security and access control, backups, recovery, replication, and basic concepts in distributed databases and cloud services.

Question formats vary: theoretical questions; practical tasks such as writing queries or outlining a schema; case studies about business requirements; multiple-choice items; and hands-on labs. Good questions are clear, self-contained, and specify expected outputs and evaluation criteria.

Approaching such questions involves defining requirements, selecting appropriate data models, justifying design choices, considering trade-offs, and describing testing and validation. In interviews, emphasis is commonly placed on correctness, efficiency, scalability, and an understanding of edge cases and real-world constraints.

Databasespørsmål is used across software development, data engineering, and database administration to assess fundamental and applied knowledge of database systems.
