This page is part of the [[Getting Started]] Section.
BaseX offers a It introduces you to the standalone console command-line mode from which all [[Commands|database commands]] can be executed.The article on the [[Database Server]] provides numerous examples for running commands in the console mode(note that the GUI does ''not'' interact with the client/server architecture)of BaseX.
=Startup=
First of all, please launch a '''standalone''' version of BaseX: double click on the '''BaseX''' icon, or run the <code>basex</code> script. [[Startup#Standalone|Follow this link]] for more information (or check out the additional [[Command-Line Options#Standalone|The command-line options]]).client can be started as follows:
=Create a database=* Run one of the {{Code|basex}} or {{Code|basex.bat}} scripts.* If you have installed BaseX on ''Windows'', click on the '''BaseX Standalone''' icon.
Various [[Command-Line_Options#Standalone|command-line options]] are available to simplify batch processing. The [[Start_Scripts|start script]] can be adjusted for individual purposes (e.g. if the default memory limit is too restrictive). Please note that the standalone client must not be used if you perform parallel (concurrent) read and write operations on your databases. See [[Startup#Concurrent Operations|Concurrent Operations]] for more details. =Operations= ==Create a Database== * To create a database you need an XML document, e.g. [httphttps://files.basex.org/xml/factbook.xml factbook.xml].
* Save this document to your working directory.
* Type in the following command to create and open the database:
; Where is the database stored?
By default, databases are stored in the <code>BaseXDatabasex/data</code> directory, which is located in your home folder.Depending on your [[Configuration]], the location of your home folder varies. For example, on a Mac it's <code>/Users/John</code>, if your name is John. If you are working with the ZIP or EXE distribution, the directory will be named <code>data</code> and reside in the application directory.
==Execute a queryQuery==
The [[Commands#XQUERY|XQUERY]] command lets you run a query.
* For example, this the following query returns all country nodes in the currently opened factbook database.
<code>
> [[Commands#XQUERY|XQUERY]] //country
</code>
=More database commands=Database Commands==
* The following command lists all databases than can be opened by the currently logged in user:
> [[Commands#XQUERY|XQUERY]] db:open("factbook")//country
</code>
 
=Close or delete a database=
* To [[Commands|close]] the current database, please type:
* Use the [[Commands#DROP DB|DROP DB]] command to delete a database:
<code>
> [[Commands#DROP DB|DROP DB]] xmarkfactbook
</code>
=Create a collection=Multiple Resources==
'''What is One database can contain not only a collection?'''single, but millions of documents. All documents can have a different structure.
With BaseX the following commands, you can group documents into one logical collection. A collection is a create an empty database that contains and add two or more documents. Collections accept any type of XML documents, regardless of their structure.It is also possible to address resources via URLs:
Let's add the xmark.xml document to the factbook database to create a collection. The name of the original factbook database remains.
 
* First make sure factbook is opened:
<code>
> [[Commands#OPENCREATE DB|OPENCREATE DB]] factbookstore</code> * Now add the xmark.xml document: <br/>
<code>
> [[Commands#ADD|ADD]] xmarkfactbook.xml</code> =Delete a document= * Deleting a document from a collection is easy:<br/>
<code>
> [[Commands#DELETEADD|DELETEADD]] http://files.basex.org/xml/xmark.xml
</code>
Make * Deleting a document from a database is easy, but make sure that the collectiondatabase, which contains the '''xmark.xml''' addressed document, is currently opened. =Delete a collection= Deleting a collection is the same as deleting a database. * To delete the collection factbook, type:
<code>
> [[Commands#DROP DBDELETE|DROP DBDELETE]] factbook.xml
</code>
==Backup and restoreRestore==
* To backup your database, type:
</code>
'''Where is the backup-file stored?''' The backup-file is stored in the database directory.The file is named It contains the name of the database and a timestamp: <code>factbook[db-timestamp.zip</code> (<code>db_namename]-[timestamp].zip</code>).To restore the If a database is to be restored, and if several backups exist, the file backup with the newest timestamp is taken. [[Category:Beginner]]
