Data Base Connectivity refers to the methods and technologies that allow applications to communicate with a database. This connection enables software to send queries, retrieve data, and perform updates on the stored information. Common standards for database connectivity include ODBC (Open Database Connectivity) and JDBC (Java Database Connectivity), which provide a consistent interface for different types of databases. Using these connectivity methods, developers can build applications that interact with various database management systems (DBMS) like MySQL, PostgreSQL, or Oracle. This flexibility allows for efficient data management and retrieval, making it easier to develop robust applications that rely on structured data.
