database connections
A database connection is a communication link between an application and a database. It allows the application to send queries and receive data, enabling users to interact with stored information. This connection is essential for tasks like retrieving, updating, or deleting data within the database.
To establish a database connection, an application typically uses a database driver or API that provides the necessary protocols. Once connected, the application can execute commands using a structured query language, such as SQL, to manage the data effectively. Proper management of these connections is crucial for performance and security.
