JDBC, short for Java Database Connectivity, is a standard Java API (Application Programming Interface) that enables Java programs to interact with databases. It provides a set of classes and methods for executing SQL statements and managing database connections from a Java application.
JDBC acts as a bridge between the Java programming language and various database management systems (DBMS). It allows developers to write database-independent code, which can be executed with different databases without any changes to the application code.
The core functionality of JDBC revolves around establishing a connection to a database, executing SQL queries and updates, and processing the results. It provides a unified interface for accessing different types of databases, including relational databases such as Oracle, MySQL, and PostgreSQL.
JDBC follows a driver-based architecture, where different JDBC drivers customized for various databases are required. These drivers handle the communication between the Java application and the database.
Using JDBC, developers can perform various database operations like creating tables, inserting, retrieving, updating, and deleting data. It also supports transaction management, allowing applications to maintain the ACID properties of the database (Atomicity, Consistency, Isolation, Durability).
In summary, JDBC is a Java API that facilitates the interaction between Java applications and databases. It provides a standardized way of accessing and manipulating databases, making it easier to develop database-driven applications in Java.
