      Top 5 Technical Interview Questions Asked Database Administrator

      • Context: ACID (Atomicity, Consistency, Isolation, Durability) properties are the cornerstone of reliable transaction processing in a database system.
      • Expected Answer:
        • Atomicity: Ensures that a transaction is treated as a single unit, which either fully completes or fully fails.
        • Consistency: Ensures that a transaction brings the database from one valid state to another, maintaining database invariants.
        • Isolation: Ensures that concurrent transactions occur independently without interfering with each other.
        • Durability: Ensures that once a transaction is committed, it remains persistent even in the case of a system failure.
      • Context: Backup and restore procedures are critical for data recovery and disaster recovery planning.
      • Expected Answer: The candidate should explain the process for creating backups (e.g., full, incremental, differential backups) and restoring databases. They might also discuss tools and commands specific to the DBMS (e.g., pg_dump for PostgreSQL, mysqldump for MySQL, or RMAN for Oracle).
      • Context: Indexes are essential for optimizing query performance by allowing faster retrieval of records.
      • Expected Answer: An index is a data structure that improves the speed of data retrieval operations on a database table. Candidates should explain different types of indexes (e.g., B-tree, Hash indexes) and discuss scenarios where indexes can improve performance, as well as cases where indexes might negatively impact performance (e.g., on write-heavy operations).
      • Context: Deadlocks occur when two or more transactions prevent each other from accessing resources, leading to a standstill.
      • Expected Answer: The candidate should describe the process for detecting deadlocks (e.g., using logs, system monitoring tools) and methods for resolving them, such as transaction timeout settings, deadlock detection algorithms, or altering the transaction sequence.
      • Context: Understanding different types of indexes is crucial for optimizing database performance.
      • Expected Answer:
        • Clustered Index: Sorts and stores the data rows in the table based on the key values. Each table can have only one clustered index, as the data rows can be sorted in only one order.
        • Non-Clustered Index: Creates a separate structure from the data rows and includes pointers to the actual data. A table can have multiple non-clustered indexes.
