TD Utilities run faster than other ETL tools in case 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.Re usability 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.
