No worries Dave,

The datablade dictates the optimal data placement strategy for it's particular datatypes. Multiple datablades can be combined so that different data types can be addressed in single queries.

UDO Datablades define data type, functions and indexing method. If you are not using that data type, or don't need to utilise the functions in the datablade (eg. data scrubbing datablade), then you simply don't address any qeuries to the blade.

The UDO option is targetted at complex data opportunities and you would choose the datablades to suit the application.

Complex data opportunities do exist in the data warehousing space- where a finance company may need time-series data, or a retailer may wish to look at maps along with their business data.

In these situations Informix is unique in it's technology and performance. Being optimised for OLTP, mixed mode or DW doesn't matter, but I suppose it could be all three depending on the application.

I hope that clarifies. Cheers.
Matt.
