<!-- Rest der Beschreibung -->
It discusses strategies, patterns and automations to help develop and maintain complex software.


The course includes bi-weekly practice sessions to teach the students practical skills using excercises and examples.

At the end of the semester each student has to turn in a project, in which they use their new found skills in developing a small contained application.

==Erste Schritte mit GraphIT==
#'''GraphIT-Account einrichten'''
##Account anlegen (gerne mit Pseudonym oder Initialen): [[Special:CreateAccount]]. 
##Einen ''Graph User'' (einfach ein Item) mit gleichem Namen anlegen (siehe z.B. das Item Q630: [[Item:Q630|Markus Mustermann]]):
###auf [[Special:NewItem]] gehen oder oben im Menü "Items → New Item" auswählen.
###Label (für Sprache Englisch): ''<eigener Name>''
###Description (für Sprache Englisch): ''Student at University of Regensburg (<eigener Name>)''   // Hinweis: in WikiBase dürfen unterschiedliche Items nicht die gleiche Beschreibung haben, deshalb bitte den eigenen Namen noch dranhängen
###Button 'Create' anklicken
##Statements ''beim Benutzer-Item'' hinzufügen (siehe z.B. das Item Q630: [[Item:Q630|Markus Mustermann]]):
###'[[Property:P3|instance of]]' (P3) + '[[Item:Q167|Student]]' (Q167)
###'[[Property:P28|username]]' (P28) + Benutzernamen (siehe Schritt 1)
###'[[Property:P25|participates in]]' (P25) + [[Item:Q1022|ASE WS 2024]] (Q1022)
##Auf der eigenen Benutzerseite (des Accounts) einen Link zum eigenen Item anlegen:
###[https://graphit.ur.de/w/index.php?title=Special:MyPage&action=edit Benutzerseite anlegen/bearbeiten]
###Folgenden Text dort einfügen und Seite speichern (mit eigenem Item statt Platzhalter): <code><nowiki>My GraphIT item: [[Item:Q123]]</nowiki></code>. Achtung: das Item muss ein Link sein, d.h. entweder im grafischen Editor verlinken oder im Quellcode-Editor in eckigen Klammern schreiben.
#'''Vorkenntnisse und Interessen angeben'''
##Auf https://test.graphit.ur.de/app/src/pages/selectionTools/ einmal mit Benutzername und Passwort (aus Schritt 1) anmelden. Achtung: das Passwort wird momentan beim Eintippen angezeigt.
##Oben rechts die Lehrveranstaltung "ASE 24WS" auswählen.
##Im angezeigten Graph die damit verbundenen Themen anschauen.
##Alle Themen als "completed" markieren, mit denen man sich schon befasst hat (auswählen und Taste '1' drücken bzw. den Button auf der rechten Seite). 
##Mindestens fünf Themen als Interessen markieren (auswählen und Taste '2' drücken bzw. den Button auf der rechten Seite).
##'''Änderungen speichern über den 'save'-Button unten rechts!'''
##Auf der eigenen Item-Seite überprüfen ob die Interessen und Vorkenntnisse korrekt dokumentiert wurden.
Als ein Beispiel kann [[Item:Q157|Max Mustermann]] angesehen werden. Für eine detailiertere Übersicht kann die Seite [[ExampleStudent]] besucht werden.
