: '''factbook''' is the name of the database <br/>: '''factbook.xml''' is the initial input of the database<br/> ; Where is the database stored? By default, databases are stored in the <code>basex/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. ==Execute a Query=See = The [[Commands#XQUERY|XQUERY]] command lets you run a query.* For example, the following query returns all country nodes in the currently opened factbook database.<code>> [[Commands#XQUERY|XQUERY]] //country</code> * You can also run queries in files:<code>> [[Commands#RUN|RUN]] /Users/John/query.xq</code> ==Database Commands== * The following command lists all databases than can be opened by the currently logged in user:<code>> [[BaseX GUICommands#LIST|LIST]]</code> * To open an existing database, execute the following:<code>> [[BaseX ServerCommands#OPEN|OPEN]]factbook</code> * To get information on the currently opened database, type:<code>> [[Getting Started GuideCommands#INFO|INFO]]</code> * You can also address a database within your query with the [[CategoryDatabase Module#db:open|db:Beginneropen]]function:<code>> [[Commands#XQUERY|XQUERY]] db:open("factbook")//country</code> * To [[Commands|close]] the current database, please type: <code>> [[Commands#CLOSE|CLOSE]]</code> * Use the [[Commands#DROP DB|DROP DB]] command to delete a database:<code>> [[Commands#DROP DB|DROP DB]] factbook</code> ==Multiple Resources== One database can contain not only a single, but millions of documents. All documents can have a different structure. With the following commands, you can create an empty database and add two documents. It is also possible to address resources via URLs: <code>> [[Commands#CREATE DB|CREATE DB]] store</code><br/><code>> [[Commands#ADD|ADD]] factbook.xml</code><br/><code>> [[Commands#ADD|ADD]] http://files.basex.org/xml/xmark.xml</code> * Deleting a document from a database is easy, but make sure that the database, which contains the addressed document, is currently opened:<code>> [[Commands#DELETE|DELETE]] factbook.xml</code> ==Backup and Restore== * To backup your database, type:<code>> [[Commands#CREATE BACKUP|CREATE BACKUP]] factbook</code> * To restore your database, type:<code>> [[Commands#RESTORE|RESTORE]] factbook</code> The backup file is stored in the database directory.It contains the name of the database and a timestamp: <code>[db-name]-[timestamp].zip</code>.If a database is to be restored, and if several backups exist, the backup with the newest timestamp is taken.
