1. Round Trip Engineering

Round-trip engineering (RTE) is a functionality of software development tools that synchronizes two or more related software artifacts, such as, source code, models, configuration files, and other documents.

2. Traditional Software Engineering Disciplines

Round-trip engineering is closely related to traditional software engineering disciplines: forward engineering (creating software from specifications), reverse engineering (creating specifications from existing software), and re-engineering (understanding existing software and modifying it).

3. Phase in Round Trip Engineering

In round-trip engineering we want to be able to edit "anything" in the project and then to be able to do

requirements <-> analysis

analysis <-> design

design <-> implementation

5

4. Forward Engineering

Forward engineering is the "normal" software development process.

Although there are several different development models, they are involved with the idea that:

requirements -> analysis

analysis-> design

design-> implementation

6

5. Reverse Engineering

Reverse engineering is the "normal" software development process reversed (not really…)

Anyway, the basic idea is that we may want to go in the reverse order:

implementation -> design

design -> analysis

analysis-> requirements

6. Reverse Engineering of Software

  "Reverse engineering is the process of analyzing a subject system to create representations of the system at a higher level of abstraction." It can also be seen as "going backwards through the development cycle". In this model, the output of the implementation phase (in source code form) is reverse-engineered back to the analysis phase, in an inversion of the traditional waterfall model.

7. Characteristic

1. Round-trip engineering is often wrongly defined as simply supporting both forward and reverse engineering. In fact, the key characteristic of round-trip engineering that distinguishes it from forward and reverse engineering is the ability to synchronize existing artifacts that evolved concurrently by incrementally updating each artifact to reflect changes made to the other artifacts.

2. Another characteristic of round-trip engineering is automatic update of the artifacts in response

to automatically detected inconsistencies.

8. Need of Round Trip Engineering

The need for round-trip engineering arises when the same information is present in multiple artifacts and therefore an inconsistency may occur if not all artifacts are consistently updated to reflect a given change. For example, some piece of information was added to/changed in only one artifact and, as a result, it became missing in/inconsistent with the other

artifacts.

9. Tools Used in Round Trip Engineering

1. Rational Rows

2. ArgoUML

3. Visual Paradigm Suite for UML

10. Rational Rows

Rational Rose is a software where the UML can be model. Here Rational is the name of the software, ROSE stands for Rational Object Software Engineering.

To draw the UML Diagram in Rational Rose:

Start Rational software, in that Rational Rose Enterprise Edition. After that Rational Rose Enterprise Edition will be activated.

11. Parts of Rational Rose Window

11.1. View Table

It contains:

a. Use case view

b. Component View

c. Logical View

d. Deployment view

14

11.2. Diagram Tool Bar

This can contain the tools of the corresponding diagram in which we are going to draw

11.3. Diagram Window

In this window we can draw the diagram

11.4. Message Window

It contains the message of documentation of the corresponding diagram

11.5. Log Window

This is the place where the errors can be displayed when we are drawing the diagram

12. Conclusion

• The Round trip engineering is the combination of Forward Engineering and Reverse Engineering.

• Round-trip engineering (RTE) is a functionality of software development tools that synchronizes two or more related software artifacts.
