My work with Vstar ended at the beginning of this year as we (Vectornova and Jsoftware) decided we could better pursue separate paths.
My interest in a database based on J has only increased. In partnership with a few clients we are working on a major upgrade of JDB to a commercial product. This was the topic of my talk at the J conference in Toronto in July. The working name of the new product is JD (J Database). In a few words: it is a high-performance, columnar database that shares some characteristics with Vstar and KDB, but is firmly placed in a J levaraged development environment. It is moving into production at one client, and will be in the hands of a few early adopters over the next month or so. Jsoftware is actively looking for partners who can help fund and drive JD development.
