JDBC (Java Database Connectivity) is a Java API (Application Programming Interface) that enables Java applications to interact with databases. The purpose of JDBC in Java applications is to provide a standard way to communicate with databases, irrespective of the type of database being used.
JDBC API enables Java programs to execute SQL (Structured Query Language) statements and retrieve data from a database. JDBC API also provides interfaces for connecting to and managing database connections, which are important for managing database transactions, committing and rolling back changes, and handling errors.
JDBC drivers are used to connect Java programs with specific types of databases, such as MySQL, Oracle, or PostgreSQL. These drivers are either included in the Java platform or provided by different database vendors.
Overall, JDBC plays a critical role in Java applications that need to store, update, and retrieve data from a database. By using JDBC, Java developers can build robust and efficient applications that can interact with databases in a platform-independent and consistent manner.
