Cache' is a MUMPS implementation. From a timing perspective, it is a peer to PICK, although there does not appear to be any history of common specifications. It has historically been a layer within applications in the health care vertical market. I believe it is multidimensional in a similar way to PICK being multi-dimensional. By that I mean that it is NOT a MOLAP tool,but permits non-1NF structures (as it should;-)

But it is NOT, I repeat NOT, POST-relational from a timeline perspective. Both PICK and MUMPS implementations that have been done after relational modeling arose have called themselves post-relational. While the implementation itself comes after relational models, the data model for Cache' is from MUMPS and that pre-dates at least the popularization of relational modeling.

I recall readin a site that someone pointed me to once that talked about PICK and MUMPS and I don't see that offhand, but could look for it again if important to you. Cheers! --dawn Received on Tue Jun 22 2004 - 15:17:06 CEST
