Technical Support Analyst Skills
1. SQL
SQL (Structured Query Language) is the common tongue of relational databases. Ask questions of data, shape it, clean it, and move it where it needs to go.
Why It's Important
When tickets hinge on facts, SQL lets you dig straight into the database, verify assumptions, trace patterns, and generate answers without waiting on someone else. Faster root causes. Cleaner reporting. Less guesswork.
How to Improve SQL Skills
Lock down the fundamentals: SELECT, JOINs, filtering, grouping, and subqueries. Get comfortable with INSERT, UPDATE, DELETE, and schema basics.
Level up with indexes, query plans, normalization, and constraints. Learn when a window function beats a subquery.
Practice on real data: write troubleshooting queries for incidents, build saved views, and create ad-hoc reports.
Explore analytical functions like ROW_NUMBER(), RANK(), and window frames for trend analysis and deduping.
Use the right tools: a SQL client with explain plans, formatting, and snippets speeds everything up.
Read execution plans and profile slow queries; shave milliseconds by fixing predicates and indexes before they snowball.

User problems often orbit identity. Passwords, permissions, access, group policy—AD gives you one place to untangle them.
How to Improve Active Directory Skills
Harden and patch domain controllers. Keep replication healthy; monitor DNS and time synchronization like a hawk.
Apply least privilege. Use role-based delegation, tiered admin accounts, and privileged access workstations.
Audit and alert. Track changes to high-value groups, GPOs, and service accounts. Review sign-in anomalies.
Clean house: stale accounts, orphaned SIDs, unmanaged service principals. Implement lifecycle processes.
Strong password policies and MFA where possible. Consider LAPS for local admin password rotation.
Document recovery: backups, system state, and a rehearsed forest recovery plan.
Know hybrid: sync basics with cloud identity providers and how conditional access affects user experience.
