DBC, or Data Base Connectivity, refers to a standard method for connecting applications to databases. It allows software programs to communicate with various database management systems, enabling them to retrieve, manipulate, and store data efficiently. DBC is essential for developers who need to integrate database functionality into their applications. In the context of programming, DBC often involves using specific drivers or APIs that facilitate this connection. Common examples include ODBC (Open Database Connectivity) and JDBC (Java Database Connectivity). These tools help ensure that applications can work with different types of databases, promoting flexibility and interoperability.
