Abdeckung nach Kategorie

Kategorie Repository Dateien Sidebar Links Abdeckung
src 95 8 8.4%
security 33 17 51.5%
features 30 13 43.3%
development 38 11 28.9%
performance 12 10 83.3%
aql 10 8 80.0%
search 9 8 88.9%
geo 8 7 87.5%
reports 36 9 25.0%
architecture 10 7 70.0%
sharding 5 5 100.0% ✅
clients 6 5 83.3%

Durchschnittliche Abdeckung: 47.4%

Kategorien mit 100% Abdeckung: Sharding (5/5)

Kategorien mit >80% Abdeckung:

  • Sharding (100%), Search (88.9%), Geo (87.5%), Clients (83.3%), Performance (83.3%), AQL (80%)

Nächste Schritte

Kurzfristig (Optional)

  • Weitere wichtige Source Code Dateien verlinken (aktuell nur 8 von 95)
  • Wichtigste Reports direkt verlinken (aktuell nur 9 von 36)
  • Development Guides erweitern (aktuell 11 von 38)

Mittelfristig

  • Sidebar automatisch aus DOCUMENTATION_INDEX.md generieren
  • Kategorien-Unterkategorien-Hierarchie implementieren
  • Dynamische "Most Viewed" / "Recently Updated" Sektion

Langfristig

  • Vollständige Dokumentationsabdeckung (100%)
  • Automatische Link-Validierung (tote Links erkennen)
  • Mehrsprachige Sidebar (EN/DE)

Lessons Learned

  1. Emojis vermeiden: PowerShell 5.1 hat Probleme mit UTF-8 Emojis in String-Literalen
  2. Ampersand escapen: & muss in doppelten Anführungszeichen stehen
  3. Balance wichtig: 171 Links sind übersichtlich, 361 wären zu viel
  4. Priorisierung kritisch: Wichtigste 3-8 Docs pro Kategorie reichen für gute Abdeckung
  5. Automatisierung wichtig: sync-wiki.ps1 ermöglicht schnelle Updates

Fazit

Die Wiki-Sidebar wurde erfolgreich von 64 auf 171 Links (+167%) erweitert und repräsentiert nun alle wichtigen Bereiche der ThemisDB:

✅ Vollständigkeit: Alle 35 Kategorien vertreten
✅ Übersichtlichkeit: 25 klar strukturierte Sektionen
✅ Zugänglichkeit: 47.4% Dokumentationsabdeckung
✅ Qualität: Keine toten Links, konsistente Formatierung
✅ Automatisierung: Ein Befehl für vollständige Synchronisierung

Die neue Struktur bietet Nutzern einen umfassenden Überblick über alle Features, Guides und technischen Details der ThemisDB.
