    Study Notes

    Enterprise Data Models

    • Enterprise Data Models (EDMs) are integrated views of data produced and consumed across an entire organization.
    • EDMs are the foundation for all other data systems within an organization.

    Traditional Data Models

    • Traditional data models aim to provide a single, primary data store for core business applications (accounting, finance, personnel, etc.)
    • Data is stored centrally, and applications then access this data.

    Data Integration Challenges

    • Data integration often results in fragmented data across different departments and applications.
    • This leads to a lack of a single, consistent truth about data for all departments.

    Enterprise Data Models (EDMs) - Pros

    • Provide an integrated view of data across the organization
    • Independent of how data is stored or accessed
    • Independent of the specific applications used by the organization
    • Provides a single, integrated data definition for the entire organization.
    • Provides a framework for supporting planning, building, and implementation of data systems.
    • Necessary for data integration

    Enterprise Data Models (EDMs) - Cons

    • EDM becomes stale before production if not correctly planned.

    Distributed Database Management Systems (DDBMS)

    • A DDBMS allows read-write access to, and read-only access to, underlying databases from applications.
    • It manages multiple underlying databases. This is a key concept in data integration since it centralises different data sources.

    Data Warehouses and Read-Only Access DBs

    • Data warehouses are used to store data for reporting and analysis.
    • They typically have read-only access.
    • Data warehouses hold data from various sources.

    Objectives of Any EDM

    • Eliminating data chaos to bring order to reporting and analytics.
    • Building a foundation for other data technologies.
    • Converting data "slogans" into actionable strategies.
    • Ensuring alignment with organizational structure and culture.

    Modern Challenges for EDMs

    • Data volumes are rapidly increasing.
    • Big Data technologies are needed to effectively deal with these volumes.
    • There is a need for a well-structured and well-formulated roadmap.
    • Crucial factors like data quality, ownership, system extensibility, and integration need to be addressed in such a roadmap. Strategic systems planning is also vital.

    Types of Data Models

    • Conceptual, Logical, and Physical models are all part of an overall integrated data model.
    • Business requirements (data model) is an aspect of a design that needs to account for business requirements as the final step.

    Why Data Modeling is Important in Enterprise Data Management

    • Data modeling mitigates complexity and increases collaboration among data stakeholders.
    • It uncovers connections between disparate data elements by using metadata and semantic processes
    • It captures and shares how the business uses data.
    • Establishes a more governed approach to data design and deployment.
    • Creates a higher quality of data with standardized design tasks.
    • Facilitates more agile and governable data architecture by standardizing the lifecycle of data sources.

    Benefits of EDMs

    • Modeling fosters true data collaboration, offering a single source of truth
    • Intuitive business glossaries and metadata repositories allow users to access and understand data
    • Data intelligence is enhanced, leading to better decision-making.

    Levels of EDM

    • Subject Area Model is a division of data into areas such as revenue, operation, support.
    • Conceptual Model is based on identified business practices; linking major concepts in each area.
    • Conceptual Entity Model recognizes crucial business entities and relationships through understanding company needs.

    Data Model vs. Data Architecture

    • Data modeling focuses on data representation, while architecture focuses on tools and storage platforms.
    • Data modeling emphasizes data accuracy, while data architecture focuses on data safety and infrastructure.
    • Data models represent limited business concepts (and how they relate), whereas architecture extends to the entire organization.

    Data vs. Information Architecture

    • Data architecture designs systems for data interpretation and storage; while information architecture creates systems for meaningful information input, storage, and analysis.
    • Data is a collection of raw facts and figures versus information which involves processing raw data.

    Data Architecture

    • Data architecture sets data standards, envisioning all interactions between various data systems.
    • Data integration is dependent on data architecture, requiring the coordination of interactions between data systems
    • Data architecture describes data structures used by a business and its computer applications.

    Data Architecture Processes

    • Conceptual- A model of all business entities
    • Logical- The logic of how the entities are connected
    • Physical- How the data will be stored for functionality.

    Information Architecture

    • Information architecture organizes content, pages, and data to help users understand the structure of a particular system

    Information Architecture Components

    • Organization systems- Different categories where information is placed
    • Labeling systems- Ways to represent information or classify data items to meet user needs
    • Navigation systems- Ways to move from one piece of information to another
    • Searching systems- Finding information such as typing specific keywords for effective searching.

    Eight Principles of Information Architecture Design

    • Object-oriented principle- Recognising content like a living thing with lifecycles.
    • Choice principle- Minimising the number of choices
    • Disclosure principle- Briefly previewing information
    • Exemplar principle- Using examples for categories
    • Front door principle- Considering alternate site entry points beyond the home page
    • Multiple classifications principle-Providing multiple ways of classifying items to address different user needs
    • Focused navigation principle-Maintaining a clear and simple navigation system
    • Growth principle-Creating a website structure that can adapt as needed.

    Value of Information Architecture

    • Improves employee productivity, sales, and reputation.
    • Enhances member acquisition, reduces marketing costs, and live support costs.

    Models for Content Organization

    • Single page
    • Flat
    • Index
    • Daisy
    • Strict Hierarchy
    • Multidimensional hierarchy

    Enterprise Information Architecture (EIA)

    • EIA links technical and data architecture elements with the enterprise-wide strategic plan and goals.
    • It ensures a logical organization of information related to enterprise-wide objectives and strategies. This includes business rules, objectives, and information requirements.
    • EIA accounts for application systems, relationships between applications and data, and the technology infrastructure.

    Information Architecture and Big Data

    • Big Data's volume, velocity, and variety challenge traditional architectures.
    • Information architecture provides necessary structure for creating metadata and associations with various related data sources
    • It enables efficient processing and analysis of big data sources, including combinations of structured and unstructured sources.
