Discuss CIW 1D0-541 Exam Topic 4 Question 117

The exhibit shows a table called Activity Relation that relates a unique student identification

number with a sports activity and a fee for participating in that activity. A student can participate

in only one activity. The key for the relation is Student_ID. What consequence would occur if the

tuple for Student_ID 1001 were removed?

AAn update anomaly would occur.

BAn insertion anomaly would occur.

CA deletion anomaly would occur.

DBoth an insertion anomaly and a deletion anomaly would occur.

Suggested Answer: C

C is the safest bet. Deletion impacts integrity directly.

Yuki 6 months ago

I feel like B is unlikely. Insertion issues don't fit here.

Beatriz 7 months ago

I lean towards D. Both anomalies could occur if linked data is lost.

Omer 7 months ago

But what about A? An update anomaly could happen too.

Cory 7 months ago

Agreed, C makes sense. Data loss is a problem.

Monte 7 months ago

Just one activity per student, so it's a clear deletion issue.

Crissy 8 months ago

Wait, are we sure about that? Seems a bit off.

Marilynn 8 months ago

I think it could cause an insertion anomaly too, right?

Crista 8 months ago

Definitely a deletion anomaly!

Lilli 8 months ago

I'm going to go with C) A deletion anomaly would occur. Seems like the most logical choice here.

Nan 8 months ago

Haha, the answer is obviously C) A deletion anomaly would occur. Who would even think an insertion anomaly would happen? That's just silly.

Janey 9 months ago

Hmm, I think the answer is B) An insertion anomaly would occur. If we remove the tuple, we won't be able to add new students to the database.

Laura 9 months ago

I'm pretty sure the answer is D) Both an insertion anomaly and a deletion anomaly would occur. Removing the tuple would prevent us from inserting new students and also delete existing data.

Maricela 9 months ago

I feel like the answer is C, but I also recall something about how removing a record could impact future data entries.

Mary 9 months ago

I'm a bit confused about the difference between insertion and deletion anomalies in this context. Could it be both?

Deja 9 months ago

I remember practicing a question like this, and I think it had to do with how removing data can affect the integrity of the table.

Armando 9 months ago

I'm pretty confident on this one. Removing the tuple for Student_ID 1001 would mean we can no longer access that student's information, which would lead to a deletion anomaly. The answer is C.

Augustine 10 months ago

Okay, let's think this through step-by-step. The key is the Student_ID, so if we remove that tuple, it would affect the ability to insert or delete data. I'm leaning towards C) a deletion anomaly.

Sylvie 10 months ago

Removing Student_ID 1001 means losing their activity info.

Ludivina 10 months ago

I think it's C. Deleting a student causes issues.

Angelica 10 months ago

I think if we remove the tuple for Student_ID 1001, it might lead to a deletion anomaly, but I'm not entirely sure.

Sina 10 months ago

The correct answer is C) A deletion anomaly would occur. Removing the tuple would mean we lose information about that student's participation, which is a deletion anomaly.

Maybelle 11 months ago

The correct answer is C) A deletion anomaly would occur. Removing the tuple for Student_ID 1001 would result in the loss of information about that student's participation in the sports activity.

Rikki 11 months ago

Hmm, I'm a bit confused about the difference between insertion and deletion anomalies. I'll need to review those concepts before attempting this.

Melodie 11 months ago

This looks like a classic database question about anomalies. I think I can handle this - I just need to remember the definitions of the different types of anomalies.

↳ replying to Melodie

But what about the insertion anomaly too?

Lashandra 5 months ago

↳ replying to Melodie

I think a deletion anomaly is the main issue here.

Timothy 6 months ago

↳ replying to Melodie

Removing that tuple could really mess things up.

Nancey 6 months ago

↳ replying to Melodie

Yeah, it's all about understanding the definitions.

Dominga 6 months ago

↳ replying to Melodie

I see what you mean about anomalies.
