Make sure to read the IDC white paper, "Because Not All Data is Flat:
IBM's U2 Extended Relational DBMSs". The IDC white paper compares the
strengths of the extended relational approach with the more commonly
used relational approach and highlights the advantages of the extended
relational approach in terms of development, performance and
maintenance of the data server. It includes an overview of IBM UniData
and UniVerse, their suitability for use in embedding in vertical
applications and how these data servers are meeting the needs of
today's development challenges.
You will find the paper posted under the Highlights section on the
right-hand
side of the U2 home page:
