Introduction

📊 Dive into the data job market! Focusing on data analyst roles, this project explores 💰 top-paying jobs, 🔥 in-demand skills, and 📈 where high demand meets high salary in data analytics.

🔍 SQL queries? Check them out here: Project Folder

Background

Driven by a quest to navigate the data analyst job market more effectively, this project was born from a desire to pinpoint top-paid and in-demand skills, streamlining others work to find optimal jobs.

Data hails from Hugging Face. It's packed with insights on job titles, salaries, locations, and essential skills.

The questions that were intended to be answered through SQL queries were:

  1. What are the top-paying data analyst jobs?
  2. What skills are required for these top-paying jobs?
  3. What skills are most in demand for data analysts?
  4. Which skills are associated with higher salaries?
  5. What are the most optimal skills to learn?

Tools Used

For the deep dive into the data analyst job market, I harnessed the power of several key tools:

  • SQL: The backbone of the analysis, allowing to query the database and unearth critical insights.
  • PostgreSQL: The chosen database management system, ideal for handling the job posting data.
  • Visual Studio Code: Go-to for database management and executing SQL queries.
  • Git & GitHub: Essential for version control and sharing the SQL scripts and analysis, ensuring collaboration and project tracking.

	job_title,
	job_location,
	job_schedule_type,
	salary_year_avg,
	job_posted_date,
    name AS company_name
FROM
    job_postings_fact
LEFT JOIN company_dim ON job_postings_fact.company_id = company_dim.company_id
WHERE
    job_title_short = 'Data Analyst' AND 
    job_location = 'Anywhere' AND 
    salary_year_avg IS NOT NULL
ORDER BY
    salary_year_avg DESC
LIMIT 10;
