Data Strategy
- Purpose: To ensure that data is treated as a valuable asset, helping the organization gain a competitive advantage, improve operational efficiency, and comply with regulations.
- Definition: A data strategy is a comprehensive plan that outlines how an organization will manage, use, and govern its data assets. It includes the vision, goals, and roadmap for leveraging data to achieve business objectives.
- Scope: Covers data governance, data management, data quality, data privacy, and how data is used for decision-making and innovation.
- Focus: High-level planning and alignment with business goals.
Data Architecture
- Purpose: To ensure that data systems are scalable, reliable, and aligned with the organization’s data strategy, enabling efficient data management and access.
- Definition: Data architecture defines the structure, integration, and management of an organization’s data systems and data flows. It provides the blueprint for how data is stored, processed, and accessed across the organization.
- Scope: Includes data storage solutions, data integration processes, data warehouses, databases, data lakes, and the tools and technologies used to manage and access data.
- Focus: Technical design and implementation of data systems.
Data Models
- Purpose: To provide a clear and precise structure for data storage, ensuring data consistency, integrity, and efficiency in how data is accessed and managed.
- Definition: Data models are detailed representations of data structures that define how data is organized, related, and used within databases, ODS, and data warehouse etc. They serve as a blueprint for how data is stored and retrieved.
- Scope: Includes entity-relationship diagrams (ERDs), data flow diagram (DFD), relational models, schema definitions, and the specific data attributes, types, and relationships within data sources.
- Focus: Conceptual, Logical and physical design of data relationships and structures.
