Question
Which of the following statements best describes the
role of the JDBC package in Java programming?Solution
The JDBC (Java Database Connectivity) package is a crucial part of Java's database interaction framework. It provides a standard API that allows Java applications to connect to relational databases and perform various database operations. Key Aspects of JDBC: • Database Interaction: JDBC provides a set of classes and interfaces that facilitate communication between Java applications and relational databases. This allows developers to execute SQL queries, updates, and retrieve results from the database. • Standard API: JDBC offers a consistent API that abstracts the underlying database system, enabling Java applications to interact with different databases (e.g., MySQL, Oracle, PostgreSQL) using the same set of interfaces.
