JDBC is a Java API that performs a SQL statement. In fact, the JDBC itself is a trademark name of a product. Relative to ODBC (Open Database Connectivity open database connection), JDBC can also be regarded as "Java Database Connectivity". It consists of a set of classes written in Java language. JDBC has become a standard API for tools / database developers, and users can use pure Java API to write database applications.
Using JDBC can easily transfer the SQL statement into any relational database. In other words, users do not need to write a program for each relational database. Write the unique program with JDBC API to send SQL statements to any of the databases. Java combined with JDBC allows programmers to run on various database systems after you only write a database application. Since the Java language has the advantages of robust, safe, easy to use, easy to understand and automatically download to the network, so it is an excellent base language for database applications. Now you need to find a way to make Java applications with a variety of different database dialogues, while JDBC is a mechanism for implementing this conversation.
JDBC expands the application range of Java. With more and more people in learning Java program, access requirements for Java database will become more and more urgent. MIS administrators want Java to combine with JDBC because it helps to make it easier and more economical. And each company can constantly use the installed database, easy access to information, do not take care of the DBMS system under what DBMS system. It helps to shorten the development time of new applications and greatly simplify the installation and version control of the database.
