BAD ROMANCE

performed by IT  not by Lady GaGa

Well, you never know when will good solutions be spoiled.

Here is the example.

• After DWH project was successfully finished,
• after DWH worked fine and justified investment,
• after users get used to it,
• after survival of negative critics
• after…

Somebody in IT still found reasonable to do following actions:

• to directly connect to legacy systems,
• export data,
• prepare data,
• publish OLAP cube,
• deliver OLAP report to users,

but not through DWH. Not through staging DWH area and data mart.

Perhaps reasons could be that:

• legacy system is not completely in DWH and
• certain data feed parts are missing,
• no time or lack of resources
• legacy system is scheduled for soon termination
• ease to do shortcut
• and etc.

Still, this actions mean direct spoiling of Data warehouse logic and benefits. Spoiling reasons why it was introduced at first place.

It is a bad romance.
