Product Overview


Forms2Net is a migration tool for converting Oracle©Forms applications to equivalent Microsoft©.NET applications.

From Oracle® Forms to Microsoft® .NET

Many companies are looking for strategies and tools to migrate from Oracle Development Environments (also known as Oracle Forms) to other recent environments namely Microsoft .NET.

The reasons for this interest are varied, including:

Cost savings
Increased development productivity
Platform standardization
Customer/partner alignment
Administrative or political decisions
or just the use of trendy technologies!
The Forms2Net tool

ATX Software developed Forms2Net having in mind the need to:

Minimize time, cost and risk of the migration process
Facilitate the maintenance of the application by development teams already in place
Preserve the semantics (functionality) of the original system
Scope of Forms2Net

Forms2Net works at the application level. Users choose what transformations they want regarding the database layer: whether to continue using an Oracle database or migrate to SQL Server. The connectivity with the data layer is based on Data Access Components on top of Microsoft ADO.NET technology that allows the customer to work with different database providers in an independent way.

Migration of database schema and of the data itself is not targeted by Forms2Net. Other complementary solutions are available on the market, namely Microsoft SQL Server Migration Assistant.

The resulting code is C# for .NET Windows Forms. Check out future features on the tool:

Current features on Forms2Net 1.1:

Add-in to Microsoft Visual Studio
Support for Oracle Forms 4.5, 5.0 and 6i
Generates C# code
Generates Windows Forms Applications
Features on Forms2Net 2.0:

Support for Microsoft Visual Studio 2005
ASP.NET code generation
Enhanced conversion for Windows Forms
New Migration Report feature
Evaluating the migration effort

Typically, more than 75% of the final code is automatically migrated by the Forms2Net tool – the exact value depends on the complexity and structure of the original application.

The Forms2Net Analyzer is an auxiliary tool that browses the original application and produces a report on the time and effort involved in the migration process.

Online help supports the manual conversion process, explaining each specific situation and displaying a list of possible options for code completion.

Mind the gap!

All migration techniques have to address the semantic gap that separates the original from the target environment. Contrary to typical conversion methods that simply try to map, on a 1:1 basis, syntactic constructs between programming languages, the power of Forms2Net resides in a sophisticated reengineering approach where it is also code structures and not merely language constructs that are transformed to the desired target.

This approach provides the following advantages:

The percentage of the converted code is greater than the 1:1 mapping approach and of significantly higher quality because:
The code is transformed to a completely new architecture that follows .NET best practices
It does not maintain the Oracle style of code structures
The migration works at the semantic level by recognizing Oracle code patterns and transforming them into the .NET code patterns.
It is a .NET development enabler in the sense that produces or uses developed components that are seamlessly integrated with the Microsoft Visual Studio .NET environment

Development teams can fine-tune and evolve the migrated application using all the functionalities of Visual Studio .NET, for instance editing generated GUI components.

The gap between the original application structure and the new .NET application depends on the choice for the target user interface technology. The migration to .NET Windows Forms is much more efficient than migrating to .NET Web Forms because Oracle Forms structure concept is closer to Windows Forms concepts than to Web Forms, enhancing transformation mapping between the application units.
