Database Connectivity refers to the methods and technologies that allow applications to communicate with a database. This connection enables applications to send queries, retrieve data, and perform updates, ensuring that users can access and manipulate information stored in the database efficiently. To establish Database Connectivity, developers often use specific protocols and drivers, such as ODBC (Open Database Connectivity) or JDBC (Java Database Connectivity). These tools help standardize the way applications interact with different types of databases, making it easier to integrate and manage data across various systems.
