5. SQL
SQL lets you peek under the hood—validate data, verify side effects, and confirm that the app and database agree.
Why It's Important
You can test beyond the UI. That means confident checks for data integrity, auditing, and complex business logic.
How to Improve SQL Skills
Nail the fundamentals: SELECT, INSERT, UPDATE, DELETE, WHERE, ORDER BY, GROUP BY, HAVING.
Work with joins and subqueries: INNER/LEFT/RIGHT joins, EXISTS, CTEs—compose readable queries.
Practice often: Daily query exercises, sample datasets, and real test data validation.
Understand schema design: Keys, indexing, normalization—write queries that scale.
Use SQL in test cases: Pre/post conditions, data seeding, and result verification.
Read query plans: Spot slow queries, add indexes, and avoid table scans when possible.
Keep a snippets library: Reuse patterns for pagination, deduping, and date math.
Learn vendor quirks: MySQL vs. PostgreSQL vs. SQL Server—dialect differences matter.

6. Python
Python is clean, friendly, and everywhere. Perfect for small utilities, data checks, and automation that grows with you.
Why It's Important
It shortens the path from idea to script. Less boilerplate, more testing momentum.
How to Improve Python Skills
Master core syntax: Data types, control flow, functions, modules, virtual environments.
Adopt testing frameworks: pytest or unittest for structure, fixtures, and parametrization.
Automate real tasks: CSV/JSON parsing, REST calls, log scrapers, simple UI or API checks.
Version control everything: Use Git branches and clear commits for your scripts.
Lean on libraries: requests, json, csv, pathlib, logging—tools you’ll reach for daily.
Refactor often: Functions, modules, and docstrings that make scripts shareable.
Keep learning: Small daily exercises beat rare big bursts.
