Metadata Management Overview

Metadata Management Capability

• Fundamental concepts: Understand people, process, and technology aspects of metadata management.
• Data Element: A unit of data defined by attributes, identification, representation, and permissible values.
• Critical Data Element (CDE): Essential to business success; must be tagged to prioritize resource management effectively.
• Criteria for CDE identification: Business relevance, data required for key processes, and unique identifiers like Customer ID.

Overview of Metadata Management

• Metadata management: Involves managing data about data, specifically regarding data models and structures, not actual content.
• Key components include: Business terms, glossary attributes, logical models, and physical database schemas.
• Critical Data Element at the center of metadata management, indicating significance in data governance.

Business Metadata

• Business glossary: Contains business terms, definitions, synonyms, and taxonomies related to CDE.
• Taxonomy classifications determine how data elements are categorized.
• Business rules dictate compliance for data elements, enhancing data quality management. Example: Legal name definitions for businesses.

Roles and Responsibilities

• Business Owner: Accountable for data definition, quality, and value.
• Data Steward: Operational oversight and interaction with subject matter experts; ensures data quality processes.
• Technical Owner: Technology specialist accountable for data system compliance.
• Data Custodian: Oversees data storage and standards enforcement, can be assigned to multiple personnel.

Technical Metadata

• Technical metadata: Describes data elements from a technical perspective—includes logical and physical data models, and their relationships.
• Examples of association between business and technical metadata include mapping CDEs to attributes within database entities.
• Data lineage defines the traceable path of data from source to output, crucial for auditing and compliance.

CDE Data Standards

• CDE data standard: Represents a holistic view of CDE encompassing both business and technical metadata (referred to as "360 view").
• Achieving a complete view enables effective data management and answers critical questions about data definitions, origins, and uses.

Metadata Collection Process

• Key activities in metadata management:
  • Identify critical data elements through business requirement analysis.
  • Collect business metadata (terms, definitions, rules).
  • Gather technical metadata (data representations and lineage).
  • Create CDE data standards by associating business and technical metadata.
  • Enforce CDE data standards across the organization, integrating all metadata roles.

System Development Lifecycle (SDLC)

• Metadata management must be integrated into the SDLC for effective application development and standard enforcement.
• Emphasis on maintaining data standards throughout the entire application lifecycle.

Technology Support for Metadata Management

• Essential features of metadata management tools:
  • Centralized metadata repository.
  • Ability to define and manage consistent terms and definitions.
  • Metadata extraction capabilities from various tools and systems.
  • Creation of associations between different metadata repository elements.
  • Version control across multiple metadata sources.

Key Takeaways

• Critical Data Elements are foundational to effective metadata management.
• Business metadata encompasses definitions, rules, and ownership perspectives, while technical metadata focuses on system representation and integration.
• Metadata management formalizes processes and assigns responsibilities to ensure effective governance and usage of data elements.
• Tools and technology are essential for sustaining a robust metadata management capability within organizations.

Metadata Management Capability

• Comprises people, processes, and technology aspects essential for effective management of data.
• Data Element is characterized by attributes, identification, representation, and permissible values.
• Critical Data Element (CDE) is vital for business success, requiring tagging for resource management prioritization.
• Identification of CDEs is based on business relevance, necessity for key processes, and unique identifiers like Customer ID.

Overview of Metadata Management

• Involves managing data about data, focusing on models and structures rather than actual content.
• Key components include business terms, glossary attributes, logical models, and physical database schemas.
• CDEs play a central role in metadata management, highlighting their importance in governance.

Business Metadata

• Business glossary comprises terms, definitions, synonyms, and taxonomies related to CDEs.
• Taxonomy classifications dictate how data elements are categorized, enhancing comprehension and organization.
• Business rules are established to ensure compliance for data elements, improving data quality (e.g., definitions of legal names for businesses).

Roles and Responsibilities

• Business Owner is responsible for data definition, quality assurance, and delivering business value.
• Data Steward manages operational tasks and collaborates with subject matter experts to uphold data quality.
• Technical Owner serves as a technology expert ensuring compliance of data systems.
• Data Custodian oversees data storage and maintains standards, often assigned to multiple personnel.

Technical Metadata

• Technical metadata provides descriptions of data elements from a systems perspective, including logical and physical data models.
• It illustrates mappings of CDEs to database attributes, linking business and technical metadata.
• Data lineage traces data flow from source to output, critical for ensuring auditing and compliance.

CDE Data Standards

• CDE data standards offer a comprehensive view of CDE, encompassing both business and technical metadata (360 view).
• Complete view facilitates effective data management and provides clarity on data definitions, origins, and uses.

Metadata Collection Process

• Key activities include identifying CDEs via business requirement analysis and collecting both business and technical metadata.
• Involves establishing CDE data standards by linking both metadata types and enforcing standards organization-wide.

System Development Lifecycle (SDLC)

• Integration of metadata management into the SDLC is vital for successful application development and adherence to standards.
• Continuous emphasis on maintaining data standards throughout the application lifecycle is crucial.

Technology Support for Metadata Management

• Effective metadata management tools should feature a centralized metadata repository.
• Ability to establish consistent definitions, extract metadata from diverse systems, and create associations between metadata elements is necessary.
• Version control is important for managing multiple sources of metadata effectively.

Key Takeaways

• CDEs are critical foundations for robust metadata management.
• Business metadata includes definitions and rules, while technical metadata pertains to system representations and integration.
• Formalized processes and assigned responsibilities ensure effective governance and usage of data elements.
• Technology tools are essential for maintaining a strong metadata management infrastructure within organizations.
