Answer / vinay sir(datawarehousing tech
It is a good question Guys....
TD Utilities run faster than other ETL tools
incase of File to Table(Import) or Table to File (Export)
Operations.Inmod and Outmod also help us to do better
prograaming while Importing and Exporting.
Major advantages of Other ETL tools than TD Utilities:
1.Heterogenous Sources and Destinations we can Operate.
(Oracle,Sqlserver,Excel,Flat Files etc....)
2.As they are providing full GUI support,degugging
is so easier.
3.Reusability of components(Informatica:mapplets,worklets
etc...) avaiable in ETL tools so if we change in main
location automatically other applications(mappings) which
are using these components can update instantly.
4.Pivoting(Normalization),Unpivot(Denormalization) we can
implement very easily in ETL tools.
5.Caching is one more advantage when we work with a source
(Heterogenous) which is not changing frequently.Some times
cache can be shared across applications etc....
Like these there are many additional advantages are there.

like Pentaho is used, real time data can be injected in to
the job which would not be possible in load utilities.
