Answer:
c. Attribute constraints
Explanation:
A data catalog identifies all of the following, except: "Attribute constraints"
The above statement is TRUE because a Data Catalog, a metadata management service, operates by searching for key data, understand and manage data for usefulness.
Data Catalog checks on the BigQuery datasets, tables, and views and checks both technical and business metadata by identifying the following attributes:
1. Data type
2. Range of values
3. Value for Instructor ID
Answer:
a) the Statement is Invalid
b) the Statement is Invalid
Explanation:
a)
lets Consider, s: student of my class
A(x): Getting an A
Let b: john
I have a student in my class who is getting ab A: Зs, A(s)
John need not be the student i.e b ≠ s could be true
Hence ¬A(b) could be true and the given statement is invalid
b)
Lets Consider G: girl scout
C: selling 50 boxes of cookies
P: getting prize
s: Suzy
Now every girl scout who sells at least 50 boxes of cookies will get a prize: ∀x ∈ G, C(x) -> P(x)
Suzy, a girl scout, got a prize: s ∈ G, P(s)
since P(s) is true, C(s) need not be true
Main Reason: false → true is also true
Therefore the Statement is Invalid
