Any database vendor (that has JDBC drivers) can add entries to this database. This database contains all JDBC driver entries sent to Sun Microsystems by JDBC driver vendors requesting to be listed in this database. Using the Web interface to this database, you can select a list of JDBC drivers based on your particular needs (for example, database support and features required). Also, you can check the Certified for J2EE check box to list only those drivers that have been certified for use with J2EE-compatible products.

:nth-child()

Typically, a two-tier model refers to a client-server model. A two-tier model for JDBC refers to clientserver architectures in which the user interface (Java/JDBC application) runs on the client machine and the database management system (that is, a database server) is stored on the server machine. Figure 2-2 represents a two-tier model for JDBC.

A validity check statement is a SQL statement that will return at least one row For Oracle, this validity check statement is "select 1 from dual" and for MySQL and Sybase Adaptive Server, it is "select 1" Without knowing the vendor parameter, it is impossible to check for the validity of database connections Also, note that without a valid database connection, you cannot get a DatabaseMetaData object Therefore, you have to make sure that you have a valid database connection before attempting to create a DatabaseMetaData object Some JDBC metadata methods require knowledge of the database vendor For example, getting the name of database tables is not the same in every case For an Oracle database, you need to select the names from Oracle s user_objects table, while for other databases, the DatabaseMetaDatagetTables() method will be sufficient..

In a two-tier model for JDBC, the actual application logic can run on either the client or the server. In two-tier architectures, the application code (Java/JDBC application) resides on the fat client, which is used to process data. The major problem with two-tier database applications is that they become complex and hard to support as the user base increases in size. For example, your database application might run fine for 20 concurrent users, but it might be problematic for 100 concurrent users. By using proper design/ programming and configuration techniques, you can avoid these problems. With a two-tier model, the database connections are expensive (it takes a long time to establish a Connection object); therefore, it is recommended you use a connection pool manager for handling JDBC connections.

This method is used for retrieving all elements that are the nth child of their parent. This method is onebased; that is, it begins counting from 1, and not 0. This method is different from the :eq() method in the following two ways: The :eq() method matches only a single element, whereas :nth-child() matches one for each parent with the specified index. The :eq() method is zero-based; that is, it begins counting from zero, whereas :nth-child() is one-based (it begins counting from one).

Typically, a three-tier model is an extension of a two-tier (so-called client-server) model. Instead of having a fat client, you move most of the business logic to the middle tier (application server level). J2EE is an example of a three-tier model. A three-tier model for JDBC has three tiers: Client tier: The client tier is responsible for presenting data, receiving user inputs and events, and controlling and managing the user interface. Middle tier (so-called application server tier): This tier is responsible for implementing the business rules (which create business objects) that are available to the client tier. IBM WebSphere (http://www.ibm.com/), BEA WebLogic Server (http://www.bea.com/), and Oracle Application Server (http://www.oracle.com/) are examples of middle tier and Web servers. Data-server tier: This tier is responsible for data storage and manages the persistence of application data. It is usually composed of one/more relational database servers (such as Oracle or MySQL) and may contain the following: Database tables/views/triggers (used primarily for storing data) Stored procedures (used to execute database on the server-side) File servers (for storing huge files such as images, PDF files, and text) Figure 2-3 presents a three-tier model for JDBC.
