Changes

* In general, there are four different ways how you can use BaseX: # BaseX comes with a [[GUI|graphical user interface]] that offers you marvellous tools for managing, querying and visualizing your (XML) data and write complex applications in XQuery.* If you prefer to work on command-line line and want to do batch processing, you # You can start BaseX as [[#Command-Line Client|standalone command-line client]].* The [[Database Server]] comes into play if you have multiple users or clientsprefer to work on command-line line and want to do batch processing.* # The [[Web Application|HTTP Server]] provides [[REST]] and [[WebDAV]] services. With [[RESTXQ]], complex web applications can be built, and the embedded [[DBA]] application allows you to work with BaseX in the browser.# The [[Database Server]] is the right choice if you have multiple users or clients, if you don’t require HTTP services, and if you tend to communicate with BaseX on a technical level.

If you want to perform parallel (concurrent) read and write operations on your databases, you must use the client/server architecture or deploy run BaseX as web application. You can safely open a database in different JVMs (Java virtual machines) for read-only access, and you will not encounter any problems when reading from and writing to different databases, but update operations from different JVMs to the same database will be rejected or may even lead to corrupt databases.
