SQL and NoSQL Flashcards

Keep your database fundamentals sharp on the go. Brush up on core SQL and NoSQL principles, commands, query patterns, and database design.

These cards are ideal for both beginners and experienced developers looking to reinforce concepts, revisit tricky queries, and solidify their understanding of relational and non-relational databases.

Pretty handy if you're a few days away from a technical interview or a database-related exam.

Packed with real-world examples and concepts often asked in FAANG interviews. Inside this deck are popular SQL queries, NoSQL use cases, and key differences between the two approaches.

If you're prepping for a tech interview and need to quickly master joins, indexing, or document modeling, this deck has your back.

A solid addition to your toolkit for a quick refresher before your next database challenge.

Each card delivers concise, color-coded information with sample queries and visual aids to make complex topics like normalization, and indexing easier to grasp and remember.
