DB Connectors are tools that enable communication between applications and databases. They allow software to send and receive data, making it possible for users to interact with databases without needing to understand the underlying complexities. These connectors can support various database types, such as SQL and NoSQL, and are essential for data-driven applications. Typically, DB Connectors come in the form of libraries or APIs that developers can integrate into their applications. They handle tasks like establishing connections, executing queries, and managing transactions, ensuring that data is accessed and manipulated efficiently and securely.
