Is there an equivalent to the Business Intelligence (BI) classes in IRIS ?
I have migrated one project from CACHE to IRIS that contains lot of classes that inherit from BI (Business Intelligence).
Usually it looks like this :
Class User.Foo Extends (%Library.Persistent, %XML.Adaptor, %BI.Adaptor)
{
}
I was wondering if there is an equivalent of those classes in IRIS, and, if not, if there is a workaround that would allow me to at least le me compile those classes.
I tried to create an empty class like that :
Class %BI.Adaptor
{
}
But I got the following error in Studio :
5883 Item '%BI.Adaptor' is mapped from a database that you do not have write permission on.
Which make sense since AFAIK this class is a system class which reside in %SYS namespace.
Product version: IRIS 2022.1
Your getting that error as your class is named %BI.Adaptor.
Create a custom name and extend %BI.Adaptor
%BI classes date back to Miner (DeepSee-1) and just were left in Caché over a decade at least
while its functionality was replaced by %DeepSee classes more than 10 years ago.
Of course, you can map all %BI.* classes to some DB where you have R/W access and import it from Caché.
that's about 300 Classes.
BUT: no one can tell you if they compile correctly
AND: you have to take care of the hidden %bi*.obj (~430) and other deployed code which you can't compile, but import and pray they work.
SO: this doesn't look like a promising approach.
Therefore I'd suggest migrating from %BI to %DeepSee in Caché first and to IRIS next
There is a SpeedMiner company that still produces such a product I guess. Calling @Lee Mei Chuan.
