As soon as the data has left the database, its meaning relies totally on the further processing applications. In complex environments this often leads to problems which are hard to fix like unexpected application behavior, lack of scalability and maintainability. XML objects are stored "natively" in Tamino. Direct storage of XML objects without further conversion to other data structures is the basis for Tamino's excellent performance. In other words, there is NO MAPPING LAYER between the XML you see and the underlying database structures. This eliminates having to do an analysis of which XML elements are to be stored in an efficiently searchable manner and which are to be stored as something like BLOBs. Finally, Software AG has been developing industrial strength database systems for something like 30 years now. Our Adabas product is widely used in environments where absolute reliability, near-infinite scalability, TRUE 24:7 availability (i.e, you can lose millions of dollars if the database is EVER offline for maintenance), etc. are requirements. Tamino is initially available on NT, and (I'm not sure of the details, commitments, etc.) will become available on a wide variety of server and mainframe platforms. > I've been asking offlist for possible consultants as our systems staff has > a strong inclination to Oracle 8i and I'm hardly fluent enough on such > software to argue based upon what I know.

I'd suggest you look closer at the actual product, its customers, and the alternatives before assuming that it's the obvious choice for XML storage.
