The Java Database Connectivity (JDBC) API
provides universal data access from the Java programming language. Using the JDBC API, you can access virtually any data source, from relational databases to spreadsheets and flat files. JDBC technology also provides a common base on which tools and alternate interfaces can be built.
The JDBC API is comprised of two packages:
- java.sql
- javax.sql
You automatically get both packages when you download the Java Platform Standard Edition (Java SE) 8.
To use the JDBC API with a particular database management system, you need a JDBC technology-based driver to mediate between JDBC technology and the database. Depending on various factors, a driver might be written purely in the Java programming language or in a mixture of the Java programming language and Java Native Interface (JNI) native methods. To obtain a JDBC driver for a particular database management system, see JDBC Data Access API.
요약하자면 JDBC는 데이터베이스로 부터 데이터 접근을 자유자재로 도와주는 자바언어로 된 API 이다. (자바언어로 데이터베이스프로그래밍을 하게끔 도와주는 라이브러리, 데이터베이스에 종속적이지 않아 생산성이 좋다.)
