BaseX vs JasDB

BaseX is a free, open-source XML database engine and XQuery processor for data-intensive web applications. It stores XML documents, binary data, and XQuery values, and handles XML, HTML, JSON, and CSV formats. Its XQuery 4.0 processor supports the W3C Update and Full Text extensions. You can operate it from the command line, in client/server mode, or through desktop and web interfaces. The graphical interface provides a query editor with syntax highlighting, keyword search, interactive visualizations, and server administration. RESTXQ supports building web applications with XQuery, while the server offers REST and WebDAV access to databases and resources. Concurrent reads, ACID-safe write transactions, user permissions, and secure authentication are supported. BaseX runs on Linux, macOS, and Windows, with API and self-hosted deployment listed. Java 17 or higher is required, and Adoptium distributions are recommended. The BaseX plan costs nothing.

JasDB is a document-based NoSQL database for rapid application prototyping and embedded use, including on Android phones and tablets. It stores JSON documents and can be embedded in software or scaled out. JasDB provides Java and REST APIs, with an entity-mapping solution for Java and JVM languages. Its REST interface can query and manipulate data, and Oberasoftware describes the query engine as having full query capabilities. Security options include users and groups, with OAuth available through the REST interface. JasDB is self-hosted and available for Android, Linux, macOS, and Windows. To start it, the quick-start instructions say to unzip the download, run start.bat or start.sh, and open http://localhost:7050. Oberasoftware has also announced a Docker container. The software is free and released under the MIT X11 License, with a restriction that redistribution to recipients be free of charges or fees. The license provides the software as-is without warranty. Oberasoftware describes the database as useful for quickly prototyping applications and accepts questions or assistance requests through its website.
