JDBCって何？ MySQL接続する為のドライバだった記憶があるが。。
JDBC is, in word, “a standard Java API for accessing relational dattabases (and almost any tabular data). JDBC is said to be short for “Java Database Connectivity” but it is not actually specified in the JDBC specification.
Critical data in an enterprise is often stored in a relational database. As such, JDBC is one of the key APIs underlying Java-based enterprise applications.
Portable database applications can be built by using JDBC drives that absorb differences between databases and JDBC APIs that are standard APIs that do not depend on specific vendors. Not only for the platform of the execution environment, but also for the connected database, it is possible to realize WORA(Write Once, Run Anywhere), which is one of the outstanding features of Java, at a higher level.
JDBC can be used from various Java components such as:
– Regular Java classes and JavaBeans
– Java application that runs on the client
– Java Applet that runs on a web client(web browser)
– Servlets and JSPs that run on a web container(J2EE server)
– Session Bean or Entity Bean that runs on EJB container(J2EE server)
ああああああああ、Javaでアプリケーション作らないといけない、という課題が露呈してしまった。あかん。
