When you look at Oracle8i, you will see more Internet-capable features than in any earlier release of Oracle's database.
Oracle8i has answered the demand for integrating database data with other kinds of data used for the Internet, such as images and multimedia files.
In this module, we will examine some of the basic tools and technologies that have been added to Oracle8i specifically to enhance and simplify
the development of Internet sites that combine database data and non-database files.
By the end of the module you will be able to:
Describe multimedia as it applies to a database
Describe how Java has been integrated into Oracle8i
List uses of the interMedia tool
Describe the Oracle Internet Directory and what it can do
Use SQLJ to deliver a Web page
List other tools and features that make Oracle8i good for Internet applications
The next lesson describes some multimedia concepts.
Now consider a three-tier architecture, shown in Figure 2 above.
A three-tier architecture has three separate components: a client, an application server, and a database server.
In implementing a three-tier architecture, you have many more choices available than you have in the traditional client-server architecture.
The communications protocol used to communicate between the client and the application server can be different from that
used to communicate between the application server and the database server.
The workload distribution among the three components can vary widely across applications.
The performance and reliability of the components in both stand-alone and networked
mode can influence the success or failure of the application.
