One solution I have seen used is to configure the staging environment so that it is identical to the production environment.

CSS is not your answer. You want to look into an abstraction on top of CSS like [SASS][1]. This will allow you to define constants and generally clean up your css.

An execution plan is theory, the execution time is reality.

Well... for one thing rather than a single event class with a union of all the properties, or 61 event classes (1 base, 60 subs), in a scenario with that much variation, I'd be tempted to have a single event class that uses a property bag (dictionary, hashtable, w/e floats your boat) to store event information.

Using RFs/RFile/RDir APIs from within a file server plugin is not safe and can potentially lead to deadlock if you're not very careful.

You can guarantee which trigger is fired first, which trigger is fired last and which ones fire in the middle by using sp_settriggerorder. If you need to synchronize more than three it does not appear possible in SQL Server 2005.

You also get a "soft delete" feature so you can give the(certain) end-users the power of "undo" - there would have to be a pretty strong downside in the mix to cancel the benefits of soft deleting.

This would be fine as long as your appliction does not require that the data is immediately deleted since you have to wait for the next interval of the cron job.

When you say the "query plan is lower", do you mean it is shorter, or that the actual cost estimates are lower?

See Herb Sutter's [Guru of the Week 54][1] for the relative merits of vector and queue where either would do.

As far as the interpreter is concerned, an underscore is just another character allowed in identifiers. It can be used as an alternative to concatenation or camel case to form multi-word identifiers.

Too complicated. The standard approach to this is to do all your work inside a transaction, so if you screw up and forget a WHERE clause, then you simply roll back when you see the "2,349,325 rows affected" result. |

If your data file contains all your records (i.e. it includes records that do not have dupicate ids within the file) you could pre-process it and produce a file that only contains records that have duplicate (ids).
If this is the case that would reduce the size of file you need to process. |
