- 500,000 records, averaging 30K *each*. Forget Sybase and Oracle on Suns;
- go for a Teradata.
-
- We run Sybase on Suns and RS6000's. We chose Sybase because, within our
- domain, they beat Oracle down quite handily (they also didn't try to
- fudge the benchmark). We put sales history in tables that typically
- reach 400K-800K each, with rows of 100-300 bytes. For mass operations,
- this is really pushing the limit; for retrieval of individual rows,
- this is okay, but watch out on any "maintenance" operation --- updating
- a field in all rows, adding a column, operations that implicitly
- require temporary tables, etc. With 30K records, you are dealing
- with blobs outside the normal record structure; you can run greater
- risks. Working with multiple databases (we tie in to Teradata, DB2 and PC
- databases), I offer the humble advice that you never want to run
- a system within an order of magnitude of its performance limits,
- and what you are suggesting is probably outside the envelope already.
-
- Unless you have some well-defined, permanently restricted requirement
- (e.g. you'd be happy to have all your data sit on CD-ROM, and just
- do queries), you might well want to see what the big boys have.
