SQL skills for product managers: What do you need to know?

In the realm of product management, data serves as a critical tool for informed decision-making, akin to a weapon for an assassin. Product managers are encouraged to develop data-oriented skills such as mastery of SQL for querying data, understanding of data visualization tools like PowerBI and Tableau, proficiency in exploratory data analysis, and familiarity with event mapping and product analytics. SQL, a programming language used for managing and exchanging data in relational database management systems, is particularly crucial as it empowers product managers to independently access and analyze data, thus improving efficiency and reducing reliance on engineering teams. Knowledge of SQL enables managers to track key performance indicators (KPIs), enhance their understanding of products, and communicate more effectively with stakeholders. While familiarity with SQL is often unnecessary for early-stage companies, it becomes essential in established firms with significant data collection. Alongside SQL, understanding the structure of databases, such as through Entity Relationship Diagrams (ERDs), is vital for product managers to effectively harness data for strategic insights and product improvements.
