"Create Database permission Denied in DataBase master.[error 262]" thanks for any help.
So you are using a staging area which is in between development and production phases. You said this staging area was a set of temporary tables. Can it be a whole separate database by itself? And if it is a database how do we make it temporary(as in what is its scope)? And whatever operations you do on the staging area do you write the code for it or generate it using code generators?
No, I said the data was temporarily stored: the tables are a permanent fixture and are used to transition that data before it gets exposed in the production tables. For my purposes it's okay for the tables to reside in the prod database but that might not suit you. There is no reason it can't be a wholly separate database: that's up to you and the requirements.
All of the code is either in stored procedures and/or c#. The usual scenario is that the tables are truncated and (in my case) filtered data is dumped into them and then other processes may work on them and then the data is moved to the primary tables.
Note that this is just how our solution works for us: it may not be right for you. Use anything like this with extreme caution, especially near production data.

We do it somewhat different to Mark, our staging table are exact replicas of the source data, this allows us to use Bulk Copy when loading the data. It also insures there are no errors in the Load part of the ELT process.
We then use stored procedures to do the transforms to the production format (these may also be staging tables in some solutions). The major benefit is that you are doing any transforms on a limited data set and it is easy to debug the procedure. It then becomes a simple matter to dump in the staging data to the production tables.
I find a well crafted ELT process leave any ETL application in the dust. There are some ETL apps that this may not apply to but the cost is extraordinary.

I have worked for some CIO's that have come up with way more atrocities than ETL or Y2K.

I think you can write bad code / processes in any language or tool. It's up to the person to find the best way to do it that works for them. Not sure about you but I have some amazingly fast SSIS packages that load a gig of data in seconds, but have seen some others that take hours doing a lot less data.
Common sense is admitting there is cause and effect and that you can exert some control over what you understand.
