Cards in this deck (10)
- 1What is reverse engineering?This term was derived from hardware development
-the process of discovering how a competitor's system worked
-(SW) the process of discovering how your own system works - 2When is reverse engineering needed?Needed when you lost the documentation of the existing system
- 3What is involved with reverse engineering?-Good for design recovery {Domain knowledge, fuzzy reasoning}
-redocumentation - 4Why would you need reconstruction?Suppose you have been given responsibility for a system that already exists, but you do not know the architecture.
-perhaps the architecture was never recorded by the original developers
-perhaps the documentation was lost
-perhaps the documentation is no longer synchronized
-the designers didn't build as architected - 5What are the 4 phases of reconstruction?Raw view extraction
Database construction
View fusion and manipulation
Architecture analysis - 6What is the raw view extraction phase?involves analyzing a system's existing design and implementation artifacts to construct one or more models of it
-Static information - obtained by observing only the system artifacts (parsers, abstract syntax tree, lexical analyzer)
-Dynamic Information- obtained by observing how the system runs (profilers, code instrumentation tools) - 7what is the database construction phase?Raw views may be too specific to aid in architectural understanding
-need to manipulate these views, to collapse information and show abstraction
-Use a database to store the extracted information
SonarJ is a tool used to encapsulate a database - 8what is the view fusion phase?Extracted views are manipulated to create fused views
-these combine static and dynamic information
Creating a fused view is like creating a hypothesis about the architecture and visualization of it to aid analysis
-these views can be interpreted, further refined, or rejected - 9What is the architectural analysis phase?This has to do with finding violations
Use different views to find violations in architecture
-SonarJ tool will help find violation - 10What comes last after the 4 phases of reconstruction ?Redo the process if it is needed
