BaseX

BaseX is a robust, high-performance XML database engine and a highly compliant XQuery 3.1 processor with full support of the W3C Update and Full Text extensions. It serves as excellent framework for building complex data-intensive web applications. BaseX is platform-independent and distributed under a permissive free software license. It comes with interactive user interfaces (desktop, web-based) that give users great insight into data. BaseX can import data in many formats including XML, JSON and CSV. Extraordinarily compact Text, Attribute, Full-Text and Path-Summary indexes accelerate the evaluation process by magnitudes. A fuzzy-match full-text option allows for approximate searches and retrieval. BaseX uses a tabular representation of XML tree structures to store XML documents. The database acts as a container for a single document or a collection of documents. Visually explore, analyze and browse XML data: Get a quick overview or dive into the details, and freely combine all views. Additionally, BaseX provides several types of indices to improve the performance of path operations, attribute lookups, text comparisons and full-text searches. BaseX provides a RESTful interface for data access. The REST server can be used to access local and remote XML databases. The output of query results in the JSON format allows AJAX developers to take advantage of the powerful XQuery language and the interoperability of XML. For ad-hoc access to databases, BaseX offers a WebDAV service, which allows users to quickly store, modify, and organize resources with a simple WebDAV-enabled file manager. In a multi-user environment, the powerful lock manager supports concurrent read operations and ACID-safe write transactions.
