XFocus/FOCUS DB - when it's better than RDBMS source?

Hello

I'm relatively new to WebFOCUS.
At first I've thought that FOCUS-files are just historical (for tutorials) and for real implementations only DBMS as Oracle, MSSQL, DB2 etc - are viable.

Now I begin to look on XFOCUS datasources.

Did I correctly understand that XFOCUS is hierarchical DB?
I suppose it must be faster than relational DBMSs in some scenarios.

I do not found any official considerations about XFOCUS - when it worth using as main source for reporting platform.

And I suspect that somebody uses it even for large amounts of data.

Do you have any suggestions in which cases XFOCUS is better than RDBMS source.

Have a Look at This

Yes, XFOCUS is pointer based HDB. Make sure all your databases all XFOCUS.

You could also try and get IBI's brilliant datawarehouse concept which did not catch on - FUSION to work.

It's now bundled with wf and look at the multi dimensional indexes which I could not get to work under 7.1.3 although they may have been fixed by now.

Will take another look

Hallo!

You wrote:
If you want quicker x10 to x20 results than Oracle dataware housing try putting it into XFOCUS files. Honest, that's what we do.

Can you get details:
1. Source data size approximately? (rows, GBs)
2. How do you fill it? Data Migrator? What about Change Data Capture - is this possible?
3. Supporting XFOCUS : defragmenting, reindexing - how this comparable with DBMS administration.

1. 2GB
2. MODIFYs scheduled by CASTER
3. We dont do incremental load but create afresh every night.

Thanks

I think I must try myself XFOCUS-configuration.
I'm interested in volumes near 30-50 GBs.
Maybe I'll send my results here

A question:
What's the beast "multidimensional index"?
Does it make wonders with queries?
