=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|command-line options]]).
=Create a database= * To create a database you need an XML document, e.g. [http://files.basex.org/xml/factbook.xml factbook.xml].* Save this document to the directory you are working in.* In the client terminal, type in:<code>> [[Commands#CREATE DB|CREATE DB]] factbook factbook.xml</code> : '''factbook''' is the name of the database <br/>: '''factbook.xml''' is the xml file, which is used to create the database<br/>  If everything works you see the following lines:<pre>Database 'factbook' created in 950.83 ms.</pre> ; Where is the database stored?By default, databases are stored in the <code>BaseXData</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 have used the Windows Installer, the directory will be named <code>data</code>, and reside in the application directory. =Working with Execute a query=The [[Commands#XQUERY|XQUERY]] command lets you run a query.* For example, this query returns all country nodes in the currently opened database.<code>> [[Commands#XQUERY|XQUERY]] //country</code> * You can also run queries in files:<code>> [[Commands#RUN|RUN]] /Users/John/query.xq</code> =Create a new database=Now we will create another database from the [http://files.basex.org/xml/xmark.xml xmark.xml] document. * Create the new database, named 'xmark'.<code>> [[Commands#CREATE DB|CREATE DB]] xmark xmark.xml</code> * Set the new database xmark as the BaseX Consolecontext:<code>> [[Commands#OPEN|OPEN]] xmark</code> * Now you can easily execute queries on your new database:<code>> [[Commands#XQUERY|XQUERY]] //people/person/name</code> =Switch the database= * You can explicitly query the factbook database with the <code>doc(...)</code> funtion, no matter what the current context is.<code>> [[Commands#XQUERY|XQUERY]] doc("factbook")//country</code>After * Otherwise, to set factbook as the BaseX Console has been startedcurrent context, execute the following:<code>HELP> [[Commands#OPEN|OPEN]] factbook</code>  * The following command lists all databases than can be used opened by the currently logged in users:<code>> [[Commands#LIST|LIST]]</code> =Close or delete a database=* To [[Commands|close]] the current context database, please type: <code>> [[Commands#CLOSE|CLOSE]]</code> * Use the [[Commands#DROP DB|DROP DB]] command todelete the xmark database:<code>> [[Commands#DROP DB|DROP DB]] xmark</code> =Create a collection='''What is a collection?'''With BaseX you can group documents into one logical collection. A collection is a database that contains two or more documents. Collections accept any type of XML documents, regardless of their structure. Let's add the xmark.xml document to the factbook database to list all create a collection. The name of the original factbook database remains. * First make sure factbook is opened:<code>> [[Commands#OPEN|OPEN]] factbook</code> * Now add the xmark.xml document: <code>> [[Commands#ADD|ADD]] xmark.xml</code> =Delete a document=* Deleting a document from a collection is easy:<code>> [[Commands#DELETE|database commandsDELETE]]xmark. Multiple commands can be separated by semicolonsxml</code> Make sure that the collection, which contains the '''xmark.xml''' document, is opened.
To evaluate commands without entering the console mode, you can use the=Delete a collection=<code>-c</code> option on Deleting a collection is the command line: <pre>basex -Vc "CREATE DB input <example/>; XQUERY /"same as deleting a database.
Database 'input' created in 124.95 ms.* To delete the collection factbook, type:<code>> [[Commands#DROP DB|DROP DB]] factbook<example/code>
Query: /=Get server information=Several commands help to explore the state of a server. For a complete list, please visit the [[Commands]] Section.
Compiling* To see all databases on the server, type:<code>> [[Commands#LIST|LIST]]</code>
