Firestore is a NoSQL database, differing from traditional relational databases in its data modeling. Instead of tables with rows and columns, Firestore organizes data into collections of documents. Each document contains key-value pairs, which can be nested to create complex hierarchical structures. This allows for flexible schemas that can evolve over time. Unlike relational databases, Firestore doesn’t support joins or transactions across multiple documents. However, it offers real-time updates and offline support, making it ideal for mobile applications.
