Effect of fragmentation
Fragmentation in databases causes data to be scattered, leading to performance issues. It includes disk fragmentation (slowing access), internal fragmentation (wasting space within structures), and external fragmentation (unused space between blocks). These reduce efficiency, requiring strategies like defragmentation for optimization.
Indexing in databases is vital for optimizing query performance. Key tips include identifying frequently queried columns, avoiding over-indexing, using composite indexes for multiple columns, maintaining indexes regularly, understanding query patterns, monitoring performance, considering index types, and testing before deployment.
Tracking SQL Server database recovery progress is vital for timely restoration and minimal downtime. Monitoring transaction logs and checkpoint progress helps manage the process efficiently. SQL Server management tools facilitate effective tracking for swift data recovery and integrity maintenance.
