Pros and cons of original source data:
Pros:
You get the exact data needed.
Only gather as much as you need.
You know where the data came from;
so can judge how reliable it is.
Cons:
Takes a long time, depending on how much is collected.
Expensive unless hiring a third party.
Pros and cons of indirect data:
Pros:
It takes less time to gather indirect data than original source.
Cheaper to obtain.
Cons:
It could be false data.
No way of telling where it came from.
Could be more expensive than collecting it yourself.
May not be able to collect the exact data you want.
If you were developing a social media site, which type of data would you use and why?
Static: Some information like date of birth doesn't need to be changed, so it wouldn't make sense making it dynamic.
Dynamic: Most information would need to be to changed at some point, like age, name, gender, relationship status.

Static: Most information wouldn't change very often if it's important government information, so archiving the information would be better if it's static.
Dynamic:
