Some python Implementations of Database Systems Algorithms.

• Undo, Redo and Undo-Redo logging Algorithms

• This directory contains the python codes of 1,2,3,4,... quantum number undo, redo and undo-redo.
• The directory structure is like 1.py, 2.py, .... etc

• Contains the logs of the undo, redo and undo-redo python scripts mentioned above.
• files are named like 1.txt_undo: undo log of 1.py file, 1.txt_redo: redo file of 1.py, and so on.

• First make sure that you have a logs directory along with your code directory.
• $python 1.py: to run the quantum number 1 file.
• change values in the name of the files [1 to 9] and see the output logs.
