Microsoft SQL Server at a glance
Microsoft SQL Server is a widely deployed relational database behind countless business applications. Microsoft services it with cumulative updates (CUs) and occasional GDRs (security-only); each version has a defined support lifecycle including mainstream and extended phases.
For admins the routine is CU management and lifecycle planning: apply cumulative updates in a test environment first, then production, minding availability groups/clustering and the documented order. Back up databases before patching. SQL Server holds sensitive data and belongs on the internal network with least-privilege access, TLS and audited logins. Watch the end-of-support dates per version — after that, security fixes stop unless you're on extended support. Keep the edition's licensing in view when planning upgrades.
