Type of Architecture by IDS-Scheer

The business architecture defines business strategies and describes organizational structures and business processes. The application architecture describes the services and application systems that support the business processes. The information architecture describes the business objects and data that are exchanged between process participants and applications. The lowest level is the infrastructure architecture, which is used to describe the physical landscape — the hardware and networks that support the application systems. Zdroj: IDS - Scheer

30

Plánované aktivity • SAP

jako primární ERP systém

• MIT

Data Warehouse bude centrální repository

• Služby

budou poskytovány v režimu 24x7

• Předpokládá • Síť

se těsnější integrace s ostatními univerzitami

MIT se bude rozvíjet tak, aby podporovala požadavky businessu

− Mohou existovat různé sítě pro výzkum − Bude používána IPv6 síť a služby pro uživatele budou diferencovány

31

Principy architektury •

Bezpečnost - aplikace by měly zajistit bezpečnost dat a přístupu k nim

•

Vlastnictví - jasné a vyhraněné vlastnictví podnikových dat

•

Investice do aktiv – bude investováno do existujících služeb a jejich potenciálu

•

Dosažitelnost – uvědomění si uživatelských požadavků (s ohledem na lokality a omezené znalosti architektury)

•

Real-time – minimalizace skrytých aktualizací dat

•

Standardy – podpora konzistentního využívání standardů
