Automation of a Digital Archive

Branche:
Media
Beschreibung:
An existing digital archive is to be expanded to meet new requirements. For mass processing, various processes (workflows) are to be automated and new import/export interfaces are to be created. In addition, new digital media (formats and types) will be managed in the future. The hitherto very pragmatic approaches are to experience more structure and formalism.
Aufgaben:
  • Technology consulting
  • Requirements management
  • Analysis
  • Design

Digital Archive

Branche:
Media

Aufgaben:
  • Concept
  • Architecture
  • Implementation
  • Documentation

Backup/Restore in a SAN/NAS environment
