# BaseX comes with a [[GUI|Graphical User Interface]] that offers you tools for managing, querying and visualizing your data and writing sophisticated applications in XQuery.
# You can start BaseX as a standalone [[Command-Line Client]] if you prefer to work on command-line line and in the terminal, or want to do batch processing.# The [[Database Server]] is the right choice if you have multiple users or clients, or if you use other programming languages and if you don’t require HTTP services, and if you tend to communicate with BaseX on a technical level.
# 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.
# It can also be embedded as a Java library in your applications.
BaseX can also be embedded as a library in your applications. ==Concurrent Operations== If you want to perform parallel (concurrent) read and write operations has been tested on your databasesnumerous platforms, you must use the client/server architecture or run BaseX as a web application. You can safely open a database in different JVMs including Windows (Java virtual machines2000, XP, Vista, 7, 10, 11) for read-only access, and you will not encounter any problems when reading from and writing to different databasesMac OS X (10.

=Startup=
First, [https://basex.org/download get a fresh copy of BaseX] from our homepage. BaseX is platform-independent and runs on any system ensure that provides an implementation up-to-date version of the [https://www.java.com Java Runtime Environment (JRE)]is available:
{| class="wikitable"
|-
! BaseX Version
! Minimum Java Version (minimum)
|-
| 10
|}
BaseX has been tested If you have several versions or distributions installed, you can type {{Code|java -version}} on numerous platforms, including command-line to check which Java version is currently used. If you have Windows (2000, XP, Vista, 7, 10, 11), Mac OS X (10we recommend the {{Code|.msi}} distributions from [https://adoptium.x , 11net/ Adoptium].x)The JRE packages are sufficient,Linux but you can also install the JDK (SuSE xxx, Debian, Redhat, CentOS, Ubuntu) and OpenBSD (up to 7.xJava Development Kit).
Next, [https://basex.org/download get a fresh copy of BaseX] from our homepage. The following distributions are available:
==Core Package==
==Full Distributions==
In addition, the '''ZIP Package''' and the '''Windows Installer''' contain extra libraries for RESTXQ web applications and other advanced features, [[Start Scripts]], and BaseX's the [[DBA]], a browser-based database administration interface ([[DBA]]).If you unzip or install BaseX, the target directory will contain the following directories:
After BaseX has been unzipped or installed, the target directory contains the following directories:{| class="wikitable"|- valign="top"! Directory! Description|-* | {{Code|bin/}}: | Start scripts (Windows, Linux).* |-| {{Code|data/}}: | The database directory.* |-| {{Code|etc/}}: | Example data: XML sample, [[Catalog Resolver|catalog and DTD files]].* |-| {{Code|lib/}}: | Extra libraries (Jetty, Tagsoup, …).* |-| {{Code|lib/custom/}}: | Directory, in which additional JAR files can be placed (such as the Saxon library).* |-| {{Code|repo/}}: | [[Repository]] for external XQuery modules (the [http://www.xqueryfunctions.com FunctX] library is included as example).* |-| {{Code|src/}}: | Directory for your XQuery scripts and other source data.* |-| {{Code|webapp/}}: | [[Web Application]] directory: home of the RESTXQ web application, REST scripts, and [[DBA]].|}
Global [[Options]] are stored in the [[Configuration|.basex configuration file]].
Various other distributions are available from the download page, most of which contain only the core package and, optionally, scripts for starting BaseX.
 
=Concurrent Operations=
 
If you want to perform parallel (concurrent) read and write operations on your databases, you must use the client/server architecture or run BaseX as a 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. Update operations from different JVMs to the same database will be rejected or may even lead to corrupt databases.
 
For example, if you only read data, you can easily run several clients (standalone, GUI, database clients) in parallel. If you update your data, however, you shouldn’t use the GUI or a standalone instance at the same time.
 
More details on concurrency can be found on the [[Transaction Management]] page.
