Java - JDBC - Introduction

Java Database Connectivity (JDBC) is a Java API used to interact with relational databases. It provides a standard interface for connecting to a database, executing SQL statements, and retrieving results. With JDBC, Java applications can connect to and work with various databases, such as MySQL, Oracle, SQL Server, and more. JDBC is included as part of the Java Standard Edition (Java SE) platform and is a crucial component of many Java-based enterprise applications that require database connectivity.

Java Database Connectivity (JDBC) is a Java API that enables Java applications to interact with various databases like MySQL, Oracle, SQL Server, and many others. JDBC provides a standard interface to communicate with databases, making it possible to write database-independent code in Java.

JDBC drivers are software components that allow Java applications to interact with a database. There are four types of JDBC drivers:

  • JDBC-ODBC Bridge driver: This driver uses the ODBC (Open Database Connectivity) driver to communicate with the database. It provides a bridge between JDBC and ODBC, allowing Java applications to use ODBC drivers to connect to databases. However, this driver is not recommended for production environments as it is less efficient than the other driver types.
  • Native-API driver: This driver is specific to the database and is written in the native language of the database. It uses the client-side libraries provided by the database vendor to communicate with the database.
  • Network-Protocol driver: This driver uses middleware to communicate with the database. It converts JDBC calls into the protocol that the database understands. This driver type is more efficient than the previous two driver types.
  • Thin driver: This driver is completely written in Java and communicates directly with the database using TCP/IP sockets. It does not require any client-side libraries, making it more portable than other driver types.

Each driver type has its advantages and disadvantages, and the choice of driver type depends on the specific requirements of the application.
