Java has a database access to MySQL and other databases via JDBC Connections (see http://java.sun.com/products/jdbc/index.jsp) for more information. What you would do would be to create a database table containing key terms, another table to hold urls, and a third to link the two together. As the spider runs it would add table entries. Database programming in Java is no harder than doing regular file i/o (assuming you know how to code in Java and know some basic SQL commands). |
