anchor.diff:  Depending on which database you want to use, add the corresponding extension:
   
   * DB2: `quarkus-reactive-db2-client`
  -* MySQL/MariaDB: `quarkus-reactive-mysql-client`
  +* MariaDB/MySQL: `quarkus-reactive-mysql-client`
   * PostgreSQL: `quarkus-reactive-pg-client`
   
   The installed extension must be consistent with the `quarkus.datasource.db-kind` you define in your datasource configuration.
  
positive.code: we refer to as Dev Services. Depending on your database type you may need docker installed in order to use this feature. Dev Services
  is supported for the following open source databases:
  
  * Postgresql (container)
  * MySQL (container)
  * MariaDB (container)
  * H2 (in-process)
  * Apache Derby (in-process)
  * DB2 (container) (requires license acceptance)
  * MSSQL (container) (requires license acceptance)
  
  
  If you want to use Dev Services then all you need to do is include the relevant extension for the type of database you want (either reactive or
  JDBC, or both), and don't configure a database URL, username and password, Quarkus will provide the database and you can just start
  
negative.code: All of these options are available as listed above.

  === MariaDB
  
  `jdbc:mariadb:[replication:|failover:|sequential:|aurora:]//<hostDescription>[,<hostDescription>...]/[database][?<key1>=<value1>[&<key2>=<value2>]]`
  hostDescription:: `<host>[:<portnumber>]  or address=(host=<host>)[(port=<portnumber>)][(type=(master|slave))]`
  
  Example:: `jdbc:mariadb://localhost:3306/test`
  
  You can find more information about this feature and others detailed in the https://mariadb.com/kb/en/library/about-mariadb-connector-j/[official documentation].
  
  === Microsoft SQL Server
  
  Microsoft SQL Server takes a connection URL in the following form:
  
  `jdbc:sqlserver://[serverName[\instanceName][:portNumber]][;property=value[;property=value]]`
  
  Example:: `jdbc:sqlserver://localhost:1433;databaseName=AdventureWorks`
  
  The Microsoft SQL Server JDBC driver works essentially the same as the others.
  More details can be found in the https://docs.microsoft.com/en-us/sql/connect/jdbc/connecting-to-sql-server-with-the-jdbc-driver?view=sql-server-2017[official documentation].
  
  === MySQL
  
  `jdbc:mysql:[replication:|failover:|sequential:|aurora:]//<hostDescription>[,<hostDescription>...]/[database][?<key1>=<value1>[&<key2>=<value2>]]`
  hostDescription:: `<host>[:<portnumber>]  or address=(host=<host>)[(port=<portnumber>)][(type=(master|slave))]`
  
  Example:: `jdbc:mysql://localhost:3306/test`
