Hi,
Following Details will give you a clear picture of advantages.

Advantage of Forms 6.0 Over Forms 5.0
PL/SQL editing enhancements
The Program Unit and Stored Program Unit editors now support a range of editing features in Microsoft Windows such as:
·Automatic indenting--As you enter code in the editors, lines are automatically indented.
·Color syntax highlighting--Keywords, comments, and strings are colored differently.
·Column and line selection--You can select columns of text as well as lines of source code.
·Drag and drop text manipulation--Highlighted text may be copied or moved by dragging and dropping.
·Multiple split views--You can create up to four separate views of the current program unit in the editor.
·Printing--You can print the current program unit.
·Unlimited undo/redo--You can undo/redo all edit actions up to the last save operation.
LOV Wizard
The LOV Wizard enables you to create and modify a list of values (LOV), a scrollable popup window that provides the user with a single- or multi-column selection list. The Wizard guides you through the process of selecting an existing record group or creating a new query record group, selecting columns from the record group for display, and formatting the LOV. You can also use the LOV Wizard in its re-entrant mode to modify existing LOVs.
Forms Runtime Diagnostics
Forms Runtime Diagnostics (FRD) is a runtime event-based logging system designed to help you debug your application.
When a form is run with FRD enabled, a combination of external user-application interactions and internal Forms processing events are written in chronological order to a log on the file system. These events can then be analyzed for correctness.
Oracle 8.0 Support
A number of the new features provided in the Oracle8 Server are available to Oracle Developer. In general, the features are in these categories:
·Greater scalability. For example, Oracle8 databases can contain tens of terabytes of data, and can support simultaneous access by up to 10000 users. Tables themselves can now contain up to 1000 columns. CHAR and VARCHAR2 datatypes can now be up to 2000 and 4000 bytes, respectively.
·Greater performance and efficiency. Use of these Oracle8 features is handled for you by Developer, and requires no actions on your part. You automatically receive the speed and reliability benefits of having your data on the Oracle8 Server.
·Large objects (sometimes called LOBs)
·User-defined objects.
Continued support for Oracle7
Developer continues its support of the Oracle7 Server, as well (Release 7.3 and later).
Oracle8 datatypes supported
Large objects (LOBs)
In Oracle8, programmers can define large objects, often called LOBs. These can store such things as text, images, sound, or video.
Oracle Developer currently supports the following Oracle8 large object datatypes:
·BLOB, or binary large object
·CLOB, or single-byte character large object
·NCLOB, or multi-byte character large object
·BFILE, or binary file (also sometimes referred to as an external file).
Using Oracle Developer, you can access the Oracle8 large object datatypes: binary large objects (BLOBs), character large objects (CLOBs and NCLOBs), and binary files (BFILEs).
These datatypes can store objects of up to 4 gigabytes in size. They are similar in purpose to the familiar Oracle7 LONG and LONG RAW datatypes, but offer a number of additional advantages.
Advantage of Forms web based applications.
Low-cost deployment and maintenance
Web applications are deployed and maintained on centralized application servers, from which they download to end users' Web browsers at runtime. To roll out a Web application, simply give end
users the application's URL. This distribution method reduces the time, cost, and complexity of deploying applications to a large or geographically-dispersed end user base, all without installing application software on their desktop machines.
Client/server migration.
The Developer/2000 Server extends and leverages the traditional strength of Oracle's client/server development suite. Developer/2000 supports all GUI widgets available in a client/server application, so you can Web-deploy any existing client/server application without changing the form definition (.FMB file)1. You can run the same Form Builder executable (generated .FMX file) in client/server mode or on the Web. Programmers experienced with Developer/2000 do not need to learn Java, JavaScript, or any other new language. "Thin client" architecture. The only client-side requirement is a Java-enabled2 Web browser. Any end user with a Java-enabled browser can run Web-enabled applications. This greatly reduces processor and memory requirements for end users' desktop machines. Support for various business objectives. With the Developer/2000 Server, you can develop internal, transaction-intensive applications (deployed on a company intranet), and electronic commerce applications (deployed on the Internet). End users accustomed to client/server applications will enjoy similar performance with the Developer/2000 Server.
NC support.
The Developer/2000 Server is designed in accordance with Oracle's Network Computing Architecture
(NCA). Developer/2000 applications run as NCA-compliant Web cartridges.
Platform independence
The Developer/2000 Server leverages Java-the emerging standard platform-independent language-to map GUI widgets to their native counterparts on other platforms. The look and feel of widgets will differ only slightly between end user platforms (Windows, Mac, Motif, and so on).
