databases

Databases are structured collections of information that are stored in a way that allows for easy access and updates. They are essential for managing persistent data in applications, particularly in web development. A database management system (DBMS) is typically used to interact with the database, enabling developers to create, read, update, and delete data efficiently.

There are various types of databases, including relational databases, which organize data into tables with rows and columns. These tables can have relationships based on key columns, allowing for flexible data access. Non-relational databases, known as NoSQL databases, also exist and are designed for different types of data and use cases. Examples of popular relational databases include PostgreSQL, MySQL, and SQLite, while NoSQL options include MongoDB and Cassandra ¹².

In Python, the DB-API provides a standard interface for database access, and libraries like SQLAlchemy and Django support various database backends, making it easier to work with databases in applications ³⁴.
