ETL managment - response (1) by BPP

Teradata offers different tools to load and unload data from Teradata DBMS.  Type this "teradata load and unload utilities" in google and go through the results for more knowledge about them.   Teredata also offers powerful sql (ANSI and extension) where you can build your own ELT procedures to move data from staging to your base edw layer.   

There are also so many ETL tools out there that can work efficiently with Teradata.  There are just too many options to consider.  But best option always depends on your business and data requirements, team size, skill sets and of course $cost (acquiring + maintenance). 

In any event you need some tool (ETL or CDC) to extract data from source system efficiently and land it some where or directly on teradata database then use different teradata (un)load tools or sql code to transform it and then load it to a base layer.   

Teradata also got a tool called teradata oleload which can extract data from other RDBMS's (or even excel files) and can load to teradata system, this is not the fastest tool or great tool but will give you starting base and some ideas as it generates different load utility scripts for you!!!

Happy Teradat(ing)!!!
