+A Spring-Boot-Example with an unlimted an easy to configure HSQL file based _permanent_ database
+
+### My intro to GitHub ... comming soon 
+### Description
+
+From time to time I need more than one _independet_ und _permanent_ databases to
+* see whats going on in my tables
+* try out my XA-Transactions 
+* do some rapid prototyping with permanent data
+
+Spring-Boot Autoconfigure just provide only *one* database out of the box, if that is enough for you, stop reading..
+to all the others ... this is comming soon ... here.
+
+Here is a little spoiler of the usage :-)
+
+``` java
+    @ConfigurationProperties(prefix = "cool.database")
+    @Bean 
+    public HSQLFileDatabaseServer coolDataBase() {
+	     return new HSQLFileDatabaseServerImpl(); // thats all, instantiate and starts the server
+    }
+
+    @Bean 
+    public DataSource coolDatabaseDataSource() {
+	     return coolDataBase.getBasicDataSourceForFileDatabaseServer();
+    }
+    
+    ...
+    and the Logging is
+    
+    Your JDBC-Connection-String:  jdbc:hsqldb:hsql://mydomain:4000/COOL_DB
+```
+so start your favorite database tool, cut&paste the jdbc-connection String and see whats happens
