Der Vortrag von Mirela Navodaru beleuchtet die Reise von Swisscom zu einem Daten-Mesh-Ansatz, der Daten-Demokratisierung, eine datengetriebene Kultur und die zentralisierte Datenverwaltung als Grundpfeiler umfasst. Schwerpunkt sind die Entwicklung von Datenprodukten, föderierte Datenverwaltung sowie die Verantwortung und Rollenverteilung innerhalb der Datenverwaltung. Durch dezentrale Strukturen sollen mehr Entscheidungsfreiheit und Effizienz in der Nutzung und Produktion von Daten erreicht werden.

business, data & tech skills
Characteristics:
• Conformed with enterprise
logical data model (SDM)
• Greenfield approach,
governance built-in
(TMForum);
• Target state OP –cross-

(Organized by Domains)
Characteristics:
• Dimensional data model
• Created by merging two or
more Conformed DPs
• Already in place, to be
migrated to the new

Swisscom Data Management – Metadata and Policies
A Central Meta Data Mgt
System provides information
on data properties, business
context and lineage
Meta Data is automatically discovered from data source
systems or obtained from decentral Meta Data Systems
The Swisscom Data Catalogue
enables transparency and fast
retrival of data and insights
Business, Quality, Security
and Compliance Data
Requirements are centrally
managed as rules
Data Product Cockpits
monitor security, compliance
and quality of the data
Data Governance processes can
proactively be triggered and partly be
automated based on data monitoring and
data catalogue information
Clearly defined data roles and
responsibilities enable efficient data
management and trust in data

"If you want to build a ship, don’t drum up the men and women to
gather wood, divide the work, and give orders. Instead, teach them
to yearn for the vast and endless sea."
A. de Saint-Exupéry
Together we can make this
dream become our reality
