New DB is exactly how engineers talk about the perpetual state of the database world. There is always a new one, the space has been in continuous ferment for fifteen years, and the question of which to use is asked constantly.
The name fits a database news and comparison resource, a benchmarking project, an open-source database, a directory of engines, or a technical publication. The comparison reading is the most useful: choosing a database is a high-consequence decision made with fragmented information and mostly vendor-authored material.
On the .org, the open-source and community readings come forward. A great many significant databases are open-source projects with foundations behind them, and that world uses this extension as a matter of course.
Five characters, no hyphen, and both parts are instantly legible to the intended audience. Short technical names are worth more because they end up typed into terminals and imported into code.
