This article is part of the [[Getting Started]] Guide. It tells you how to get BaseX running.
=Getting StartedIntroduction=
BaseX is very light-weight. It can be run and used in lots of different ways, such as a
First of all, [http://basex.org/download download] BaseX from our homepage. The following distributions are available:
==Distributions==
===Core Package===
The '''Core Package''' is a small JAR file. It contains the BaseX database management system, the XQuery processor, the client/server architecture, and the graphical user interface. It does not require any additional libraries.
===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 browser-based database administration interface ([[DBA]]).
If you work with the ZIP distribution, and if you want to make BaseX globally available, you can add the {{Code|bin}} directory to your PATH environment variable.
===Web Archive===
The '''WAR Archive''' can be embedded in existing Java web servers.
===Other Distributions===
Various other distributions are available from the download page, most of which contain only the core package and, optionally, scripts for starting BaseX.
==Requirements==
BaseX is platform-independent and runs on any system that provides an implementation of the [http://www.java.com Java Runtime Environment (JRE)]:
Linux (SuSE xxx, Debian, Ubuntu) and OpenBSD (4.x).
==Concurrent Operations==
If you want to perform parallel (concurrent) read and write operations on your databases, you must use the client/server architecture or deploy 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.
More details on concurrency can be found on the [[Transaction Management]] page.
=Standalone ApplicationStartup=
==Graphical User Interface== The * BaseX comes with a [[GUI|graphical user interface]] is the visual interface to the features of BaseX. It is a fully fledged XML editor that offers you marvellous tools for managing, querying and can be used to create new databases, perform queries or interactively explore visualizing your (XML ) dataand write complex applications in XQuery. It can be started as follows: * Double click on the {{Code|BaseX.jar}} file.* Run one of the {{Code|[[Start_Scripts#Linux.2FMac:_basex|basexgui]]}} or {{Code|[[Start Scripts#Windows: basex.bat|basexgui.bat]]}} scripts.* Execute the following command: {{Code|java -cp BaseX.jar org.basex.BaseXGUI}}* On ''Windows'': Double click on the '''BaseX GUI''' icon.* For [[Maven]] users: type in {{Code|mvn exec:java}} in the main directory of the {{Code|basex}} project. More information If you prefer to work on the GUI's command-line options can be found [[Command-Line Options#GUI|here]]. ==Command-Line Client== The [[Command-Line Client]] can be used to execute XQuery expressions or run database commands on the command line. It can also be used for both scripting and want to do batch processing your XML data. It , you can be started start BaseX as follows: * Run one of the {{Code|[[Start_Scripts#Linux.2FMac:_basex|basex]]}} or {{CodeCommand-Line Client|[[Start Scripts#Windows: basex.bat|basex.bat]]}} scripts.* Execute the following command: {{Code|java -cp BaseX.jar org.basex.BaseX}}* On ''Windows'': Double click on the '''BaseX (Standalone)''' icon. It is important to remember that the standalone mode does ''not'' interact with the client/server architecture. More information on the standalone mode's command-line options can be found [[Command-Line Options#Standalone|hereclient]]. =Database Server= * The [[Database Server]] comes into play if BaseX is to be used bymore than one user (client). It handles concurrent [[Transaction_Management|read and write transactions]], [[User Management|manages user permissions]] and [[Logging|logs all user interactions]]. By default, the server listens to the port {{Code|1984}}.There are several ways of starting and stopping the server: * Run one of the {{Code|[[Start_Scripts#Linux.2FMac:_basex|basexserver]]}} or {{Code|[[Start Scripts#Windows: basex.bat|basexserver.bat]]}} scripts. Add the {{Code|stop}} keyword to gracefully shut down the server.* Execute the following command: {{Code|java -cp BaseX.jar org.basex.BaseXServer}}. Again, the {{Code|stop}} keyword will ensure a graceful shutdown.* On ''Windows'': Double click on the '''BaseX HTTP Server (Start)''' icon, which will start both the HTTP Server used for [[#Web Application|Web Applications]] and the database server. With '''BaseX HTTP Server (Stop)''', you can shut down the server process. Pressing {{Code|Ctrl+c}} will close all connections and databases and shut down the server process. More information on the database server's command-line options can be found [[Command-Line Options#Server|here]]. ==Client== The BaseX [[Database Server#Command-Line Client|Command-Line Client]] interface can be used to sendcommands and queries to the server instance on command line. It can be started as follows: * Run one of the {{Code|[[Start_Scripts#Linux.2FMac:_basex|basexclient]]}} have multiple users or {{Code|[[Start Scripts#Windows: basex.bat|basexclient.bat]]}} scriptsclients.* Execute the following command: {{Code|java -cp BaseX.jar org.basex.BaseXClient}}* On ''Windows'': Double click on the '''BaseX Client''' icon. More information on the command-line options can be found [[Command-Line Options#Client|here]]. The default {{Code|admin}} user can be used to connect to the server: <br/>* <b>Username:</b> {{Code|admin}}* <b>Password:</b> {{Code|admin}}The password should be changed with the {{Code|[[Commands#PASSWORD|PASSWORD]]}} command after the first login.<br/> If you want to communicate with the database server programmatically, we provide clients in various [[Clients|programming languages]]. =Web Application= With the |HTTP Server, BaseX can be used to build [[Web Application]]s.It provides access to the [[REST]], [[RESTXQ]] and [[WebDAV]] services.An instance of the With [https://www.eclipse.org/jetty/ Jetty Web Server] will be created,which by default listens to the port {{Code|8984}}. Additionally, the BaseX databaseserver will be started, which is accessible on port {{Code|1984}}. It can be started as follows: * Run one of the {{Code|[[Start_Scripts#Linux.2FMac:_basexhttp|basexhttpRESTXQ]]}} or {{Code|[[Start Scripts#Windows: basexhttp.bat|basexhttp.bat]]}} scripts. Call the script with the {{Code|stop}} keyword to gracefully shut down the server.* On ''Windows'': Double click on the '''BaseX Server''' or '''BaseX Server (stop)''' icon.* BaseX can also be deployed as [[Web Application#Servlet Container|, complex web servlet]]. In the first two cases, the command-line output will look similar to the following lines (the JSP warning message [http://stackoverflow.com/questions/3521654/missing-jsp-support-in-jetty-or-confusing-log-message applications can be ignored]): <pre class="brush:xml">[main] INFO org.eclipse.jetty.server.Server - jetty-9.4.14.v20181114; built: 2018-11-14T21:20:31.478Z; git: c4550056e785fb5665914545889f21dc136ad9e6; jvm 11.0.1+13[main] INFO org.eclipse.jetty.webapp.StandardDescriptorProcessor - NO JSP Support for /, did not find org.eclipse.jetty.jsp.JettyJspServlet ...HTTP Server was started (port: 8984).Server was started (port: 1984).</pre> You can adjust the Jetty logging level by adding the following properties to the start script: <pre class="brush:xml">-Dorg.eclipse.jetty.util.log.class=org.eclipse.jetty.util.log.StdErrLog -D{classref}.LEVEL=DEBUG</pre> After that, you can e. g. open your browser and navigate to the RESTXQ start page http://localhost:8984. More information on the HTTP server's command-line options can be found [[Command-Line Options#HTTP Server|here]]. ==Database Administration== The embedded [[DBA]] is a web-based database administration interface. It application allows you to create and administrate databases, evaluate queries work with BaseX in realtime, view log files, manage users, etc. It can be accessed via http://localhost:8984/dba/the browser.
