Topic #: 9

In a Data Module a developer creates a joined view from two tables (a and b) and then joins this to another table (c). What would be the execution logic in the database?

AAll queries are collapsed and a standard join across all three tables (a, b, c) is performed.

BThe columns used in table (c) are are joined on the key to table (b) first and then the results are post-joined to table (a).

CIt makes no difference to the execution as a joined view is only used to group data items in a logical manner to help the business user find their data.

I think the execution logic might depend on how the database optimizer handles the joins. I remember something about joined views being evaluated first.

I'm pretty sure the correct answer is C, a message port. That's the SysML construct used to represent a connection point for an interaction.

Hmm, this looks like a question on the convergence of a geometric series. I'll need to think carefully about the conditions for convergence.

Hmm, I'm not too familiar with the HPE Virtual Connect SE 100 GD F32 Module for HPE Synergy. I'll need to think this through carefully.
