@Consumer, it’s been so long since I’ve been involved that I don’t know. You’d have to ask them.

Very well said, I thoroughly enjoyed this article and the knowledge that you have on this subject. Do you think that ObjectStore has been improved to make it easier to sell, have they integrated the proper programs that will make this easier on the user? Thanks for sharing you extensive knowledge on this product.

Dan, thanks for your insightful recaps. I find it ironic (if true) that ObjectStore was never ported to the one platform that was built from the ground up to support what ObjectStore does: IBM’s iSeries OS/400 (http://tinyurl.com/iSeriesOS400) with its single-level virtual storage system wherein all data resides on permanent or temporary memory-mapped pages.
“Essentially, the physical RAM on the server is a cache for this very large, single-level storage space….objects which need to persist when the system is off are maintained in persistent storage.”
Could you comment on this and the fact that 64-bit addressing finally makes the concept of an enormous memory-mapped (paged) persistent store directly feasible?

I work for a company that has developed its own GIS and implemented in most of the Latin American countries(in utility companies).
We wanted to try ObjectStore 3 years ago but they don’t offer a Trial version for the Enterprise version.
It has no sense , I mean: we tried Objectivity and Versant but ObjectStore was never tested because of that.

[...] Dan Weinreb was one of the key techies at Object Design, the company that made the object-oriented database management system ObjectStore. (Object Design later merger into Excelon, which was eventually sold to Progress, which has deemphasized but still supports ObjectStore.) Recently he wrote a pair of long and fascinating articles about Object Design, ObjectStore, and OODBMS, the first of which makes the case that “object-oriented database management systems succeeded.” [...]

Dan,

I work on a Smalltalk GemStone application for a very large company. We max out at 2000 transactions a minute. We have noticeable slowdowns at 700 transactions a minute. Our Java SQL system maxes out at 70 transactions a minute. Yes, we have ten times the throughput of Enterprise Java and (big company) SQL. Your academic critics should stop writing papers and write some software in the real world. By the way, we have B-Tree search indexes. We can query a set of six million objects in two seconds. Our DB image is in the 500 gig range.

There is a web site called oodbms.org, which calls itself "The Resource Portal for Eduction and Research". It has a lot of information and resources about OODBMS's, particularly recent developments. It has a page of download links for free or trial copy OODBMS's, and a lot of news about recent work on standardization.

David Maier of Oregon Graduate Institute, who was on Object Design's original technical advisory board, was interviewed in SIGMOD Record, and he discusses the question of the fate of OODBMS's and the object-relational DBMS's. I can't tell when this interview happened, but it was evidently during the period when Object Design was named eXcelon and was pushing the XML database technology, perhaps in the late 1990's.
