Answer:
Using version control tools like Git and Github.
Explanation:
Version control is a vital tool in programming in recent times. it helps to prevent loss of source codebase and creating unwanted folders for storing multiple codebases to prevent excess storage usage and time consumption.
Git and Github is a platform that handles version control and collaboration between co-workers. When a repository is created, its initial branch is called the master branch and when a staged code is committed, the commit is recorded. These records can be retrieved using the commit hash value and resetting the current unstaged file or code. A new branch can created to hold a different version of an application and merged later with the master branch.

Answer:
A field with a unique value
Explanation:
A primary key is a field (or a collection of fields) that contain a unique data to identify a precise row in a given table. This is used for data retrieval but also to fully identify the row to be edited in case of update.
It can be as simple as an auto-increment counter, a serial number or an email address for example.
It can also be complex and take into account a series of fields, like a combination of a date and a userID, as a simple example. In such case, the date field by itself would occur many times (many entries per day), and the userID would happen also many times (many daily entries by the userID), but the pair (date/userID) would be unique.
