I’ve been working with Express.js and building some backend applications lately. As I get deeper into development, I keep hitting the same wall when it comes to choosing databases. I’m curious about what the current market trends are showing for 2025.
Is it better to focus my time on mastering SQL databases first, or should I jump straight into NoSQL solutions? I want to make sure I’m investing my learning time in the right direction.
What do you think gives better career prospects and matches what companies are actually looking for right now?
Transitioning from frontend to full-stack development highlighted the importance of mastering SQL fundamentals. Most enterprises continue to depend on relational databases, making SQL crucial for grasping database design principles that apply broadly. However, the choice between SQL and NoSQL often hinges on your industry. Startups and companies handling unstructured data may favor NoSQL options like MongoDB, while traditional sectors like finance and healthcare often prefer PostgreSQL or MySQL. Therefore, starting with SQL, especially PostgreSQL, is advisable before exploring NoSQL, as it equips you with essential skills for any database environment.
honestly both are pretty important but if i had to pick one id say go with sql first. most job postings still ask for it and once you understand relational concepts nosql becomes way easier to grasp later
what kind of apps are you building with express? that might help narrow things down tbh. like if you’re doing real-time stuff or handling lots of user-generated content, the database choice could be pretty different. have you run into any specific pain points yet that made you think about this?
