What are the different databases used in Full Stack Application Development?
The different databases used in Full Stack Application Development include **relational databases** such as **MySQL** and **PostgreSQL**, **NoSQL** databases like **MongoDB** and **Cassandra**, and **graph databases** such as **Neo4j**. Relational databases are structured, with data organized into tables and relationships defined using foreign keys. They are suitable for applications with complex relationships and transactions. NoSQL databases are schema-less and provide flexible storage for unstructured data. They are commonly used in applications that require scalability and fast data access. Graph databases are designed to represent and store relationships between data elements efficiently. They are beneficial for applications where relationships are a key aspect, such as social networks or recommendation systems.
