JDBC

1.

JDBC (Java Data Base Connectivity,java database connection) is a Java API for executing SQL statements that provides unified access to a variety of relational databases, consisting of a set of classes and interfaces written in the Java language. JDBC provides a benchmark to build more advanced tools and interfaces that enable database developers to write database applications, while JDBC is a trademark name.

2.

with JDBC, it's easy to send SQL statements to various relational data. In other words, with the JDBC API, You do not have to write a program specifically to access the Sybase database , write a program specifically for accessing the Oracle database , or To access the Informix database and write another program , etc., programmers just need to write a program in the JDBC API , it can send SQL calls to the appropriate database . At the same time, the Java language and JDBC are combined so that programmers do not have to write different applications for different platforms , just write the program once to let it run on any platform, which is the Java language "write once, run everywhere" advantage .
