25. Reassess and Iterate

Storing Data (Optional)

After reassessing your data and revisiting any steps of the data wrangling process deemed necessary, storing your cleaned data can be the next logical step. Storing data is important if you need to use your cleaned data in the future.

Storing data isn't always necessary, though. Sometimes the Jupyter Notebook that you gathered, assessed, cleaned, analyzed, and visualized your data in, plus the original data files is good enough. Sometimes the analysis and visualization are the final products and you won't be using the cleaned data any further. If you ever want to reproduce the analysis, the Jupyter Notebook suffices.

Storing your data, in files and databases for example, will be covered in detail in lesson 2 of the course.
