  Unlocking the Power of Data Compression in SQL Server   In the world of relational databases, storage optimization is often a top priority. SQL Server, a popular relational database management system, offers two compression techniques: page compression and row compression. But how do you choose between them, and what are the trade-offs? Let's dive in and demystify these techniques. Page Compression: Maximizing Storage Efficiency Advantages: High Storage Savings: Page compression, as the name suggests, works at the page level. It employs advanced algorithms to significantly reduce the storage space required for your data. If you're dealing with a data warehouse or large datasets, this is your go-to option. Disk I/O Improvement: By shrinking the data footprint on disk, page compression can reduce the amount of data read from and written to storage. This can lead to better I/O performance, particularly for read-heavy workloads.   Disadvantages: CPU Overh...
