What are the differences and characteristics between forward engineering and reverse engineering?

Forward engineering is the process of transforming the model into code by mapping to the implementation language. Reverse engineering is the process of transforming code into model by mapping from a specific implementation language.

2. Different procedures

Forward engineering is to develop software from the goal, while reverse engineering is to get other people's ready-made software and then make a program by disassembly.

Extended data:

The reasons for reverse engineering are as follows:

Interface design. Because of interoperability, reverse engineering is used to find cooperation agreements between systems.

Military or commercial secrets. Stealing the latest research results or product prototypes of enemies or competitors.

Improve the documentation. When the original documents are insufficient, and the system is updated and the original designer is absent, reverse engineering is used to obtain the required data to supplement the explanation or understand the latest state of the system.

Software upgrade or update. Due to the change of function, compliance, security and other requirements, reverse engineering is used to understand the existing or legacy software systems, so as to evaluate the work needed to update or transplant the systems.
