Learning Outcome

You will master a crucial aspect of data analysis: version control. We will be exploring the topic in three steps:

1. Examine the underlying data model of versioning filesystems.
2. Look at how git (https://en.wikipedia.org/wiki/Git) implements versioning filesystem by providing operations repositories and commits.
3. Look at how Web services such as github https://en.wikipedia.org/wiki/GitHub drive open source development by providing distributed version control.
