Datenbankbasiertes Bilddokumentmanagement mit Web-Portal, Micro Imaging, Muenchen
15.01.2012-30.09.2014
Die Software dient zur Verwaltung und Darstellung sehr großer Bitmap-Bilder. (GB bis mehrere TB).
Der Client ist ausschließlich mit Web Technologien entwickelt (HTML5, JavaScript, CSS).
Er ermöglicht die sehr flexible Navigation, Darstellung, und Bearbeitung der Bilder und Dokumente.
Er ist kompatible mit Windows, OS-X, iOS (iPad, iPhone) WindowsPhone & Surface sowie Android.
Auf all diesen Systemen ist interaktives Zeichnen, inklusive Freihandzeichnen möglich.
Auch auf kleinen Bildschirmformaten (SmartPhone, iPhone) ist der volle Leistungsumfang verfügbar.
Der Server ist mit ASP.NET, MVC, C# und T-SQL realisiert.
Er verwaltet die Dokumente und implementiert Web Pages sowie Web APIs zu deren Verwaltung.
Zum Leistungsumfang gehören umfangreiche Sicherheitsfunktionen (Benutzer, Gruppen, Rechte, Features),
ein sehr flexibles Datenmanagement (konfigurierbar Dokumenteigenschaften und Eingabeformulare,
konfigurierbarer Drill-Down über alle Daten und konfigurierbare Tabellen und andere Darstellungen.)
Das System unterstützt, neben den Bildern, auch alle anderen Dateiformate (PDF, XL*, usw.).
Die Software kann problemlos auf Microsoft Azure Servern betrieben werden.
Im Rahmen dieser Entwicklung wurden auch ein Upload Utility (für sehr große Dateien)
sowie ein Installer entwickelt.
Diese Software wurde komplett von mir entwickelt, inklusive Architektur, Datenbankstruktur,
Software-Design, Grafikdesign, Entwicklung und Dokumentation. Sie entstand in enger
Zusammenarbeit mit dem Produktmanagement.
