This document provides an overview of JDBC (Java Database Connectivity):
- JDBC provides a Java API for updating and querying relational databases using SQL. It allows Java applications to connect to and execute SQL statements on a database.
- Every JDBC program follows a 4 step approach: 1) open a connection to the database, 2) execute a SQL statement, 3) process the result, and 4) close the connection.
- Key JDBC concepts include Statements, ResultSets, PreparedStatements, and the different types of drivers that can be used to connect to databases from Java applications.
