newdb.org
There is always a new one. The database world has been in continuous ferment for fifteen years and the question of which to use gets asked constantly, mostly answered with fragmented information and vendor-authored material.
New DB is how engineers actually talk about that state of affairs.
On the .org the open-source and community readings come forward, which is where a great deal of the significant work happens. Many of the most important databases are foundation-governed open source, and that world uses this extension as a matter of course.
The name suits a news and comparison resource, a benchmarking project, an open-source database, a directory of engines, or a technical publication.
Five characters, no hyphen, both parts instantly legible to the audience. Short technical names are worth more because they get typed into terminals and imported into code.
Available now. Enquiries welcome.
