Step 2:: Analyze the Key Concepts of Database File Maintenance
Database file maintenance involves activities that help preserve, optimize, and protect database performance and data integrity. This requires understanding the core maintenance techniques.
Step 3:: Evaluate Each Option Carefully
Let's examine each option systematically: A. Using log files to recover data - This is a CORRECT maintenance technique - Log files track database transactions - Critical for data recovery in case of system failures - Allows reconstruction of database state at different points in time B. Writing new database client software - This is NOT a typical maintenance activity - Client software development is a separate process - Not directly related to routine database maintenance - Incorrect option C. Compacting the database - This is a CORRECT maintenance technique - Reduces physical storage space used by database - Removes unused or fragmented data spaces - Improves overall database performance D. Defragmenting the database index - This is a CORRECT maintenance technique - Reorganizes index structures - Improves query performance - Helps optimize data retrieval speed
Step 4:: Determine Correct Answers
Based on the analysis, the correct options are: - A: Using log files to recover data - C: Compacting the database - D: Defragmenting the database index
Final Answer
A, C, and D are correct database file maintenance techniques.
