Relational Database Management System
Oracle provides a flexible RDBMS called Oracle7. Using its features, you can store and manage data with all the advantages of a relational structure plus PL/SQL, an engine that provides you with the ability to store and execute program units. The server offers the options of retrieving data based on optimization techniques. It includes security features that control how a database is accessed and used. Other features include consistency and protection of data through locking mechanisms.
Oracle applications may run on the same computer as the Oracle Server. Alternatively, you can run applications on a system local to the user and run the Oracle Server on another system (client-server architecture). In this client-server environment, a wide range of computing resources can be used. For example, a form-based airline reservation application can run on a client personal computer while accessing flight data that is conveniently managed by an Oracle Server on a central computer

About Oracle8
Oracle8 is the first object-capable database developed by Oracle. It extends the data modeling capabilities of Oracle7 to support a new object relational database model. Oracle8 provides a new engine that brings object-oriented programming, complex datatypes, complex business objects, and full compatibility with the relational world.
Oracle8 extends Oracle7 in many ways. It includes several features for improved performance and functionality of online transaction processing (OLTP) applications, such as better sharing of runtime data structures, larger buffer caches, and deferrable constraints. Data warehouse applications will benefit from enhancements such as parallel execution of insert, update, and delete operations; partitioning; and parallel-aware query optimization. Operating within the Network Computing Architecture (NCA) framework, Oracle8 supports client-server and Web-based applications that are distributed and multitiered.
Oracle8 can scale tens of thousands of concurrent users, support up to 512 petabytes, and can handle any type of data, including text, spatial, image, sound, video, and time series as well as traditional structured data.

About Oracle8i
Oracle8i, the database for Internet computing, provides advanced tools to manage all types of data in Web sites.
It is much more than a simple relational data store. The Internet File System (iFS) combines the power of Oracle8i with the ease of use of a file system. It allows users to move all of their data into the Oracle8i database, where it can be stored and managed more efficiently. End users can easily access files and folders in Oracle iFS via a variety of protocols, such as HTML, FTP, and IMAP4, giving them universal access to their data.
Oracle8i interMedia allows users to web-enable their multi-media data—including image, text, audio, and video data. Oracle8i includes a robust, integrated, and scalable Java Virtual Machine within the server...
