Data Modeler (Contract Role)

Background:

The Data Strategy & Governance function within Advanced Analytics (AA) CoE is very strategic to Emirates NBD Group for defining and implementing an enhanced data strategy with a future state vision to build an ecosystem of business-owned and self-describing Data Products to complement / enable all forms of Analytics, BI, Operational, Regulatory and all other data dependent use-cases for the Group (covering all entities) and thus ensure the transformation towards becoming a fully optimized data driven organization.

The new data strategy follows a federated approach for data product operations where the data landscape is broken down into Data Domains & Sub-domains and each Data Domain/Sub-domain to have a comprehensive data product roadmap which is continuously enriched/enhanced based on following three dimensions.

1. Building Foundational / Non-negotiable data products ensuring the desired functional coverage under a particular Data Domain (Producing the data products once but use it for many purposes)
2. Enabling business-value by building Business-Oriented / Consumer-aligned data products
3. Ensuring the data consumer adoption to new data products landscape and thus eliminating dependency on ungoverned data sources for data consumers by implementing required data products

Enterprise Data Modeling is an essential component of Group’s data strategy, provides structure for data products and relationship between data products which helps users across competencies to store and interact with data more effectively for a wide variety of use-cases.

The data modeler designs, implements, and documents data design patterns and data modeling solutions, which include the use of relational, dimensional, and NoSQL databases. These solutions support enterprise-wide data products implementation and enabling all forms of data dependent use-cases.

Key Responsibilities of Data Modeler:

• Be responsible for Creating / Maintaining / Optimizing conceptual, logical, and physical data models, the implementation of operational data store (ODS), data marts, and data lakes on target platforms (SQL/NoSQL) using best practices to ensure high data quality and reduced redundancy.
• Implement business and IT data requirements through new data strategy and designs across all data platforms (relational, dimensional, and NoSQL) and relevant data tools (reporting, visualization, analytics, and machine learning)
• Defines and governs data modeling and design standards, tools, best practices, and related development for enterprise data models
• Managing the enhancements / expansion of existing data models and the optimization of data query performance via best practices
• Working closely with Data Domain Specialists & Data Product Owners for the understanding of Data Product level functional specifications, obtaining the business context and consumption patterns around the data
• Creating Structure / Schema for Target Data as per business requirements (nature of data + consumption patterns) by leveraging business context & data product functional specifications
• Performing Data Profiling as may be required to arrive at future proof data model design for Data Products
• Providing Technical Specifications to development team (Data Engineering & BI teams) as per final target schema for data (functional specifications are converted to fit into target structure)
• Generating DDL (Create Table) Scripts using Data Modeling Tool, working with Technology Engineers to create the required database objects onto the respective database platform and maintaining the required enhancements.
• Works proactively and independently to address project requirements and articulate issues/challenges to reduce project delivery risks
• Working collaboratively with all involved teams and contributing to the advancement of data strategy operationalization

Skills Required:

• Bachelors/ master’s degree in information management, Computer Science & Engineering, or equivalent degree from an accredited academic institution or related experience
• Preferred Banking domain knowledge and multi-market experience
• Minimum 5+ years of hands-on relational, dimensional modeling, and/or analytic experience (using RDBMS, dimensional, NoSQL data platform technologies, and ETL and data ingestion protocols).
• Experience and knowledge across different design patterns for Data Repositories such as Data Warehouse, Data Lake, Data Lakehouse, Data Mesh, Data Fabric and enterprise big data platforms including a full understanding of end-to-end data flow cycles

Core Skills Required:

• Expertise in data modeling principles / methods including conceptual, logical & physical Data Models
• Skills/Conceptual knowledge required to create optimal data models - Star & Snowflake Schemas, Data Vault Methodologies, Dimensional Modeling techniques (Slowly Changing, Fast Changing, Snapshot methodology, Degenerated dimensions etc.), Normalization & Denormalization, Surrogate Key Concepts etc.,

Technical Skills Required:

• Hands-on expertise on data modeling tools such as (SAP Power Designer, ERWin, ER/Studio etc.,)
• Knowledge in Industry Reference data models: IBM BFMDW, Teradata FSLDM, SAP FSDM etc.,

Best Practice / Design Standard Skills Required:

• Naming standards for Schemas, Data Objects & Data Attributes
• Identifying best fit data type & length for each data attribute as part of physical data model etc.,
• Leveraging common Master & Reference Data
• Ensures no redundancy in terms of data objects design based on nature of data (Master / Transactional / Reference)
• Ensuring Data Objects are designed to provide long-term stability.

• Robust knowledge of data, systems and querying tools like SAS/SQL and proven ability to quickly learn new systems and data environments.
• Preferred knowledge across all key facets of Data Management (Data Warehousing, BI, Data Governance, Data Quality, Master/Reference Data Management, Data Privacy Management, Application side Data Management and External Data Assets Management etc.,)
• Preferred knowledge in HADOOP, Oracle, PostgreSQL & SAP HANA database technology platforms
• Preferred knowledge in interacting with Data Governance tools (Informatica AXON-EDC-DEQ)
• Collaborative team player with strong stakeholder management skills, who can think creatively and strategically while building cross-functional and cross-divisional relationships.
