Validate accessibility and operational readiness of the modelling environment for both onshore and offshore delivery teams.
Authoritative Data Register Definition-
Facilitate stakeholder workshops to identify, scope, and define authoritative data registers.
-
Document domain boundaries, business definitions, ownership, stewardship responsibilities, and relationships with upstream and downstream systems.
-
Produce Authoritative Data Register Definition Packs for each register.
Conceptual, Logical and Physical Data Modelling-
Develop conceptual data models representing high-level entities, relationships, and business rules.
-
Produce supporting Data Requirements Specifications for each conceptual model.
-
Develop logical data models defining entities, attributes, relationships, cardinality, and data types.
-
Ensure traceability between conceptual and logical models using Erwin traceability features.
-
Develop physical data models aligned to ADC’s target architecture, including:
-
IBM DB2 Warehouse schemas.
-
Databricks Delta Lake structures supporting Bronze, Silver, and Gold data pipelines.
-
Reverse engineer existing DB2 database structures where required to support reconciliation between current and target-state designs.
Data Traceability and Standards Alignment-
Maintain complete traceability between approved register definitions and conceptual, logical, and physical models.
-
Manage DDM ID Mapping Tables and Erwin Mart version logs.
-
Align data models with the Unified Data Model (UDM) and Government Information Model (GIM).
-
Maintain the GIM/UDM Alignment Register and identify gaps, conflicts, or enhancement opportunities.
Integration with Enterprise Data Governance-
Collaborate with Data Catalogue Specialists to ensure data structures are accurately represented in Microsoft Purview.
-
Support glossary alignment, schema consistency, metadata accuracy, and lineage requirements.
-
Ensure authoritative register entities and attributes are consistently represented across modelling and catalogue platforms.
Review, Approval and Compliance-
Prepare modelling artefacts for formal DDA review and approval.
-
Produce Modelling Approval Packages including:
-
Erwin exports.
-
DDM ID Mapping Tables.
-
Data Requirements Specifications.
-
GIM/UDM Alignment Register.
-
Manage review cycles, incorporate feedback, and maintain version control until formal sign-off is achieved.
Physical Model Controls-
Ensure all physical models include audit columns, logging requirements, and error-handling specifications.
-
Validate physical model structures against Databricks pipeline implementation requirements and enterprise data governance standards.
Required Skills and Experience-
Extensive experience with Erwin Data Modeler and Erwin Mart.
-
Strong background in conceptual, logical, and physical data modelling.
-
Experience with enterprise data governance and metadata management frameworks.
-
Knowledge of IBM DB2 Warehouse and Databricks Delta Lake architectures.
-
Experience implementing data modelling standards and traceability controls.
-
Strong stakeholder engagement and workshop facilitation skills.
-
Understanding of government data standards, information models, and enterprise architecture practices.
Deliverables-
Erwin Mart repository and modelling standards configuration.
-
Authoritative Data Register Definition Packs.
-
Conceptual, logical, and physical data models.
-
Data Requirements Specifications.
-
DDM ID Mapping Tables.
-
GIM/UDM Alignment Register.
