Database

Databases are essential for storing, managing, and retrieving structured data efficiently in various applications. They provide a systematic way to organize data, ensuring security, consistency, and scalability. There are different types of databases, including relational databases like MySQL, PostgreSQL, and Oracle, as well as NoSQL databases like MongoDB and Cassandra. Structured Query Language (SQL) is commonly used to interact with relational databases, allowing users to perform operations like querying, updating, and managing data. Modern databases support indexing, transactions, and replication to enhance performance and reliability. With the rise of cloud computing, database management services like AWS RDS, Azure SQL Database, and Google Cloud Firestore provide scalable and automated solutions for businesses.
