Caravel Insight

The Caravel Insight tool provides a deep understanding of any mainframe or AS/400 RPG / COBOL Legacy system in a fast, precise, and intuitive way.
Creates a 100% visual, interactive, and navigable image of the system, including all the relevant information.
Accurate pseudocode Java generators support easy and reliable reengineering processes.

Performs a detailed assessment and builds the necessary documentation.
In addition to the visual representation, all the relevant information is extracted and organized in a well-structured database (repository).

Outputs (an excerpt)

  • Verification of the integrity between sources and objects.
  • Output of the objects that have no callee or reference destination.
  • To Refer freely the contents of the repository using SQL.
  • Metrics information of each object.

In case of using with Caravel Converter

Insight is used to reveal as "Tips" the commands and statements that will be problems when perform conversion with Caravel Converter.
Caravel converter realize 100% automatic conversion if all Tips are cleared.

Benefits of using Caravel Insight

  • 01Efficient rebuilding/rewriting of the target system using Java Pseudo Code.
  • 02Reveal the problem in case of migration and investigate the effect, e.g. no source code, calling middleware, etc.
  • 03Visualize the complete internal structure and the relationships of all subsystems in black-box.

Effective support for Rewriting

Caravel Insight includes a set of tools designed to support the Rewriting of the System from zero.
Every subroutine is described with its flowchart and its Java pseudocode.

A cleaning set of tools allows to eliminate unused components and focus in the real, active system.

Taking the results of the Analysis as input, a completely new system can be rebuilt, performing a deep reengineering.

Object analysis sample

Open modal

After select any object from the list on the left, the overview(basic information, statistic information and dependency) of the selected object will be shown.

Open modal

Various type of information can be switched with the tab in the below of the window. For example, the list of files and variables will be shown on the Structure tab.

Open modal

If you select the object of the display file type, you can preview the screen image on the Preview tab.

Open modal

If you select the object of the print file type, you can preview the print image on the Preview tab.

Navigation sample

Open modal

Navigation shows the overview(such as the number of each type of programs, the number of files, the complexity of those and statics information like the number of mean steps) of the repository on the home window to understand the correlation visually with intuitive operation.

Open modal

Move to the window that shows correlation of the whole objects with only one click. Here, there are menus that allow you to intuitively perform operations such as searching for specific objects from the search window or hiding objects that are not related to the searched objects.

Open modal

From the object relationship diagram, you can select a specific object to see details. The first screen shows a list of subroutine units that compose the object. Subroutines that are not used are highlighted for clarity.

Open modal

When you open the subroutine, there is a menu that displays the flowchart with one click. Very useful for understanding the function of the subroutine.

Open modal

When you expand a subroutine, icons for legacy code and Java pseudocode are displayed along with the flowchart. Only one click is needed to jump to the both. Both can be jumped with one click. Java pseudo code is useful for improving the efficiency and reducing period of system rebuilding.

Dynamic analysis sample

Open modal

Create use cases by tagging and grouping objects related to one business flow.

Open modal

In an use case detail screen, the number of loop that performed in actual execution will be displayed, it will be the important clue for the performance improvement.

Open modal

Use cases can be traced step by step.

Open modal

When you expand each step, you can see the actual input screen and execution flow.
