A DB Connector is a tool or software component that facilitates communication between a database and an application. It allows applications to send queries to the database and retrieve data efficiently. This connection is essential for applications that rely on databases to store and manage information, such as web applications and mobile apps. DB Connectors support various database management systems, including MySQL, PostgreSQL, and Oracle. They often use standard protocols like ODBC or JDBC to ensure compatibility across different platforms. By providing a seamless interface, DB Connectors help developers focus on building features rather than dealing with the complexities of database interactions.
