With a saga, a business process that would otherwise have been implemented as a clunky batch job 1 can be built in a much more elegant and real-time manner. Saga analyzers Sagas have a powerful API, but it’s limited by the confines of C#. You can create a class that is a lousy saga but is still perfectly valid C# code.

Evaluating earlier solutions, one of the important factors in getting good performance was the ability to employ batch processing. Let’s examine the plans for two of the earlier solutions that utilized batch processing. But have we exploited it to the maximum extent possible?

This ruling in itself raises many questions: how much creativity is needed, and is that the same kind of creativity that an artist exercises with a paintbrush?

That is, does SQL Server perform a substitution process whereby it converts the original nested code into one query that goes directly against the base tables? And if so, is there a way to instruct SQL Server to avoid this unnesting process?

After we’ve cleaned up our act and matured our processes, we’ll finally be ready for a VSM tool.” .

A leaned-out IT organization capitalizing a significant proportion of its discretionary spend is highly susceptible to a perfect storm of (a) SG&A contraction, (b) IT project write-off, and (c) suspended IT investments.
