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.

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 think the correct answer is C) Entity set. A collection of data with the same properties is an entity set, right?
