Types of reverse engineering
Logic reverse engineering
Data reverse engineering
Information is extracted from the source code and stored in the physical design information storage.
Physical design information is obtained.
Logic reverse engineering
The existing database is modified or migrated to a new database management system.
Data reverse engineering
Refers to the entire process from understanding the user environment and problems to operation and maintenance.
Lifecycle of software development
This model clearly shows the activities that should be performed while implementing the project to project managers and developers.
v model
a method of developing a system or a part of a system to understand a system or to solve such issues as risks or uncertainties.
prototyping
a system is developed by extending the functions several times. the system version in each phase runs only a few limited functions, and the later version includes newly added functions in addition to those of the previous version.
incremental model
like the incremental model, the __________ is useful when the system development time needs to be reduced.
evolutionary model
means to develop new software using existing software or software knowledge.
software reuse
