4、y (JDBC) is a set of classes that can be used to develop client/server applications that work with databases developed by Microsoft, Sybase, Oracle, Informix, and other sources. With JDBC, you can use the same methods and classes in Java programs to read and write records and perform other kinds of
5、database access. A class called a driver acts as a bridge to the database sourcethere are drivers for each of the popular databases. Client/server software connects a user of information with a provider of that information,and its one of the most commonplace forms of programming. You use it every ti

Web servers provide the requested information,if it can be found, for the client. One of the biggest obstacles faced by database programmers is the wide variety of database formats in use, each with its own proprietary method of accessing data.To simplify using relational database programs, a standard language called SQL (Structured Query 2 Language) has been in
