This article is part of the Advanced User's Guide. It lists statistics on various databases instances that have been created with BaseX, with value and full-text indexes turned off. The URLs to the original sources, if available or public, are listed below.
Databases in BaseX are light-weight. If a database limit is reached, you can distribute your documents across multiple database instances and access all of them with a single XQuery expression.
