Show Suggested Answer Hide Answer
Suggested Answer: C

The resource that is the best way to lock rows in SQL Server is RID. RID, or Row IDentifier, is an attribute that uniquely identifies each row in a heap table in SQL Server. A heap table is a table that does not have a clustered index, which means that the rows are not stored in any particular order. A RID consists of the file number, page number, and slot number of the row in the database. A RID can be used to lock rows in SQL Server to prevent concurrent access or modification by other transactions or users. A RID lock is a type of lock that locks a single row using its RID. A RID lock can be applied using theHOLDLOCKorXLOCKhints in aSELECTstatement. The other options are either not related or not effective for this purpose. For example, TID, or Transaction IDentifier, is an attribute that uniquely identifies each transaction in a database; SID, or Security IDentifier, is an attribute that uniquely identifies each user or group in a Windows system; PID, or Process IDentifier, is an attribute that uniquely identifies each process in an operating system.Reference:CompTIA DataSys+ Course Outline, Domain 3.0 Database Management and Maintenance, Objective 3.3 Given a scenario, implement database concurrency methods.

Wait, is the ER model the one with the entity-relationship diagrams? I'm so confused now.

This question is making me hungry. I could really go for a tuple of tacos right about now.

I'm going with A) Relation set. That's what we call a group of entities with the same attributes, isn't it?

D) Tuples sounds like the right answer to me. Isn't a tuple just a row in a database table?

I'm not sure, but I think it could also be A) Relation set, as it represents a collection of tuples with the same attributes.

I agree with Darrel, because an entity set represents a collection of entities that share the same attributes.

Hmm, I'm not sure. Isn't an ER model a better description for a collection of data with shared attributes?

I agree, an Entity set makes more sense for data with shared attributes.
