+# Bremen Calling
+
+___
+
+Projekt zur verbesserten Kommunikation der maritimen Partner bei Schiffsanläufen in Bremen.
+
+## Anforderungen
+
+## Architektur
+
+Die Architektur besteht aus einer Datenbank und einem in Python implementierten Backend, das eine API zu Verfügung stellt. Diese API ist als OpenAPI 3.0 spezifiziert.
+Die Anwendung selbst kommuniziert nur über diese API mit der Datenbank. Es sind damit unterschiedliche Anwendungsplattformen denkbar, etwa eine Web-, Mobile- oder Windows Desktop Anwendung.
+In dieser [Folie](docs/Architektur.pptx) ist ein Bild / Überblick enthalten.
+
+Ein erster Gedanke des Datenbank-Layouts sieht folgendermaßen aus:
+![image](docs/datenbank.jpeg)

+## Entwicklung
+
+### Postman
+
+Zum Debuggen der Flask App verwende ich dieses Tutorial:

+# Database Bremen Calling
+
+## Server
+
+mariadb v 10
+
+## Getting started
+
+- Execute 'create_schema.sql' and import 'sample_data.sql'
+
+If the database is updated or changed, please update these files.
+To avoid errors, it is best to drop the entire database, edit the create script and re-import the sample data.
+
+## Creating the dump file
+
+```bash
+mysqldump -u [username] -p --no-create-info --complete-insert bremen_calling > sample_data.sql
+```
+
+## Removing existing tables
+
+We want only to remove the tables in order to preserve user privileges
+
+```sql
+SELECT concat('DROP TABLE IF EXISTS `', table_name, '`;')
+FROM information_schema.tables
+WHERE table_schema = 'bremen_calling';
+```
+
+outputs complete drop statements
+
+```sql
+SET FOREIGN_KEY_CHECKS = 0;
+-- Your semicolon separated list of DROP statements here
+DROP TABLE IF EXISTS `notification`;
+DROP TABLE IF EXISTS `role`;
+DROP TABLE IF EXISTS `ship`;
+DROP TABLE IF EXISTS `participant`;
+DROP TABLE IF EXISTS `times`;

+  <!-- 
+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.
