Implementation of Collibra Integrations and Data Governance Processes for Slovak Telekom and T-Mobile CZ

Slovak Telekom and T-Mobile CZ unified and automated their Data Governance processes through the implementation of the platform Collibra, which brings significant digitalization of processes at the level of personalization, automation, auditability, and data accessibility across the organization, turning them into a unified Data Governance management tool. The project delivered integration with existing metadata sources, automation of control processes, and the creation of a robust solution for managing and auditing data assets within the GCP environment.

Challenge

Fragmented metadata sources: Multiple independent models in SSAS and MSSQL environments without unified management.
Limited visibility of data relationships between physical and logical models.
Necessary automation of governance processes: Auditing roles, validations, and notifications required manual intervention.
Requirement for cloud scalability: The goal was to migrate key processes to GCP (IDA model) and streamline management.

Solution

The project combined technical metadata integration with the implementation of Data Governance processes in Collibra.

Integration of SSAS Tabular models into Collibra: Import of core structures (databases, models, tables, hierarchies, levels, calculated groups, and items). Relationships between columns, levels, calculated items, and measures were also implemented.
Connection to the physical model: Where the source was clearly defined, a link to physical tables in MSSQL/FedDWH was created.
Collibra repository backup: Implemented through DataIngest and dbt into GCP within the IDA model. A weekly snapshot ensures recoverability and change tracking.
Technologies used: Collibra REST/Core API, SSIS (for SSAS data transfer), Python for supplementary transformations, DataIngest + dbt, GCP (IDA model), MS Fabric, and GitLab CI.

Implementation:

The project was carried out throughout 2025::

Q1/2025: Solution analysis and PoC.
Q2–Q3/2025: Integration of SSAS Tabular models, import testing, and Collibra API setup.
Q3–Q4/2025: Deployment of control processes in Fabric, configuration of notifications and automations.
End of 2025: Production rollout in the GCP (IDA) environment and launch of standardized governance workflows.

Control processes in Fabric:

Offboarding – automated removal of responsibilities after user offboarding.
Data Product Maintenance – validation and completion of missing attributes.
Responsibilities Reconciliation – alignment of roles between domains and assets.
Version Control – tracking of changes at the Data Product level and automatic notifications for consumers.

Results and benefits

Coverage of SSAS model metadata in Collibra across the entire organization.
Faster metadata import and auditing processes.
Automation of notifications and validations.
Expected reduction of incidents and manual administration by tens of percent after full deployment.
