Architecting Insights: Analytical Data Modeling - Data Engineering Process Fundamentals

Building on our previous exploration of data pipelines and orchestration, we now delve into the pivotal phase of data modeling and analytics. In this continuation of our data engineering process series, we focus on architecting insights by designing and implementing data warehouses, constructing logical and physical models, and optimizing tables for efficient analysis. Let’s uncover the foundational principles driving effective data modeling and analytics.

• Operational Data Concepts:
  • Explanation of operational data and its characteristics.
  • Discussion on data storage options, including relational databases and NoSQL databases.
• Data Lake for Data Staging:
  • Introduction to the concept of a data lake as a central repository for raw, unstructured, and semi-structured data.
  • Explanation of data staging within a data lake for ingesting, storing, and preparing data for downstream processing.
  • Discussion on the advantages of using a data lake for data staging, such as scalability and flexibility.
• Data Warehouse for Analytical Data:
  • Overview of the role of a data warehouse in storing and organizing structured data for analytics and reporting purposes.
  • Discussion on the benefits of using a data warehouse for analytical queries and business intelligence.
• Data Warehouse Design and Implementation:
  • Introduction to data warehouse design principles and methodologies.
  • Explanation of logical models for designing a data warehouse schema, including conceptual and dimensional modeling.
• Star Schema:
  • Explanation of the star schema design pattern for organizing data in a data warehouse.
  • Discussion on fact tables, dimension tables, and their relationships within a star schema.
  • Explanation of the advantages of using a star schema for analytical querying and reporting.
• Logical Models:
  • Discussion on logical models in data warehouse design.
  • Explanation of conceptual modeling and entity-relationship diagrams (ERDs).
• Physical Models - Table Construction:
  • Discussion on constructing tables from the logical model, including entity mapping and data normalization.
  • Explanation of primary and foreign key relationships and their implementation in physical tables.
• Table Optimization - Index and Partitions:
  • Introduction to table optimization techniques for improving query performance.
  • Explanation of index creation and usage for speeding up data retrieval.
  • Discussion on partitioning strategies for managing large datasets and enhancing query efficiency.
• Incremental Strategy:
  • Introduction to incremental loading techniques for efficiently updating data warehouses.
  • Explanation of delta processing.
  • Discussion on the benefits of incremental loading in reducing processing time and resource usage.
• Orchestration and Operations:
  • Tools and frameworks for orchestrating data pipelines, such as dbt.
  • Discussion on the importance of orchestration and monitoring the data processing tasks.
  • Policies to archive data in blob storage.
