Just a tool to simplify relation normalization process, evaluate database design.

menu decompose 3nf decompose bcnf

And more!

python3 main.py 

• Attribute closure
• Armstrong: ir2, ir3, ir4, ir5
• Check two Functional Dependency (FD) set is equivalent
• Find closure Functional Dependency set (FDs) from Armstrong rule set
• Minimal cover of FDs
• Find key from FDs
• Check collection of attribute is super key of relation
• Decompose relation to 3NF from FDs
• Decompose relation to BCNF from FDs
• Menu interactive
• Check current Normal Form of relation (in general normal form definition)
• Test Nonadditive Join Property after decomposition relation
• Args parser integrate click
• Reduce random order of set iterator in minimal_cover method

All code is kept in one file for portability and ease of execution.

User input binding with dynamic injection, same idea how Spring implement IoC 🤞. I love Spring btw.

Follow TDD but in a suck way 💀.
