The area of ETL has been recognised for over 20 years and the challenges are well recognised.
There is wide range of Products available in this category.
There is an overlap with other categories, such as Data Cleansing and Data Profiling,
and most of these Products occupy an expensive niche.
They are all fighting a war of attrition against
Microsoft's SSIS (qv), and probably risking obsolescence sooner or later.
If you have any comments, experiences or suggestions,
