Teradata Fundamentals
Teradata Fundamentals
About the Book
The book consists of a series of lecture notes on the corporate training the author has delivered across the world. It is meant to be as concise as possible for people working with Teradata that need practical answers now, instead of reading the whole documentation.
Since the audience is working professionals, a bit of experience working with other databases or with Teradata itself is recommended.
