What is the Wonder Robo Reverse Service?

It is a reverse engineering service that uses AI to analyze existing system source code in languages like COBOL, VB6, and Java, organize the system structure and program relationships, and automatically generate design documents.

What has become possible with this update?

The system overview and analysis progress are now visualized on the web, allowing you to monitor the analysis status and design document generation progress in real-time through a browser.

What challenges of legacy systems does it address?

It addresses challenges such as the absence of design documents, unclear current specifications, complex structures, and difficulties in analysis due to individual expertise.

In what format are the deliverables output?

Deliverables such as screen design documents, report design documents, table definition documents, process flows, and program specifications can be output in Excel format.

What types of companies are expected to use this service?

It is expected to be used by companies planning to rebuild legacy systems, for existing asset analysis in SI projects, and by organizations with long-term operational systems in local governments, financial institutions, and insurance industries.

[Visualizing Black-Box Legacy Systems on the Web] Progress Tracking Feature for Reverse Analysis Launched

Wonderful Fly Co., Ltd. has launched a new feature for its "Wonder Robo Reverse Service," which analyzes legacy systems like COBOL to generate documentation, enabling users to visualize system overviews and analysis progress via the web.

Challenges in Legacy System Modernization

"No design documents," "Unknown current specifications," "Lack of visibility into analysis progress." In the field of legacy system modernization, the 'black-box' nature of COBOL and other legacy systems is a significant challenge.

Wonderful Fly Co., Ltd. has announced the launch of a new feature for its "Wonder Robo Reverse Service," which uses AI to analyze legacy systems and generate design documentation, allowing users to check system overviews and analysis progress on the web.

This service analyzes COBOL assets, visualizing the overall system structure, program interdependencies, analysis progress, and documentation generation status. This supports understanding the structure of black-boxed legacy systems and facilitates the sharing of analysis progress during modernization projects.

Service Overview

Wonder Robo Reverse Service is a reverse engineering service that uses AI to analyze source code from legacy systems such as COBOL, PowerBuilder, VB6, and Java. It organizes system structures and program relationships before generating various design documents.

By analyzing source code, the service organizes system configurations, CALL relationships, screen/form compositions, and table information, outputting them as screen designs, form designs, table definitions, and processing specifications.

Key Features

1. Web-based System Overview for COBOL Assets Previously, understanding the structure or interdependencies of legacy systems could be time-consuming. This service visualizes analysis results to assist in grasping the structure and connections of existing systems.

2. Web-based Analysis Progress Tracking Users can check the analysis and documentation generation status via a browser. This makes it easier to verify how far the analysis has progressed, identify unanalyzed programs, and confirm if documentation is complete, facilitating progress reporting.

3. AI-Powered Design Document Generation Based on the analysis results, the service generates screen designs, form designs, table definitions, processing flows, and program specifications, all exportable in Excel format.

4. Supporting Understanding of Existing Systems For long-running COBOL systems where design documents are missing or knowledge is siloed, this service analyzes and organizes existing assets to support current state assessments and impact analyses.

Potential Use Cases

- Current state analysis before legacy system modernization (organizing structure and relationships). - Visualization of black-box systems (understanding structures in environments without documentation). - Analysis of existing assets in SI projects (analyzing existing assets and supporting investigations). - Structural assessment of systems for governments, financial institutions, and the insurance industry (maintenance support and structural verification for long-running systems).

Future Outlook

We will continue to enhance the service by advancing system dependency analysis, impact analysis, and expanding support for additional languages to support legacy system modernization.
