Data Engineering SummaryData Engineering : Step by Step Summary
Extract, Transform, Load (ETL) is a foundational data integration process that consolidates raw data from multiple disparate sources—such as CRM systems, databases, and APIs—into a single, centralized destination, typically a data warehouse or data lake. It is crucial for ensuring that data is clean, consistent, and ready for analytics, BI reporting, and machine learning.
Core ETL Process Steps
Extract: Raw data is pulled from varied sources (structured or unstructured) into an intermediate staging area.
Transform: The staged data is cleaned, formatted, and combined based on business rules to ensure consistency.
Load: The prepared data is moved from the staging area into the final target data warehouse.
Key Benefits
Data Quality & Consistency: Standardizes formats (e.g., date formats, currency) and cleans up errors.
Historical Context: Combines legacy data with new information for long-term analysis.
Automation: Automates recurring data processing tasks, saving time for data engineers.
ETL vs. ELT
ETL (Transform before Loading): Transforms data on a separate processing server before loading, ideal for complex, heavy transformations.
ELT (Load then Transform): Loads raw data directly into the target warehouse (e.g., Snowflake, BigQuery) and transforms it using the warehouse’s power. This is better for large, unstructured datasets.
Detailed Summary
1. Extract
Extraction is the first phase, where raw data is gathered from various heterogeneous sources.
Full Extraction: The entire source is copied; best for small tables.
Incremental Extraction: Only data modified since the last run is extracted.
Update Notification: Source system alerts the ETL tool of a change.
Staging Area: Extracted data is temporarily stored in a “staging area” (or landing zone) to avoid placing heavy loads on production systems during transformation.
2. Transform
This is the most compute-intensive phase, where raw data is converted into a usable format.
Cleansing: Mapping NULL values to 0, removing duplicates, and fixing errors.
Standardization: Converting character sets, date/time formats, or measurement units (e.g., kilograms to pounds).
Data Aggregation: Summarizing data (e.g., total sales per store per day).
Enrichment/Derivation: Creating new calculated values (e.g., calculating profit from revenue and cost).
Encryption/Masking: Anonymizing PII (Personally Identifiable Information) to comply with GDPR/HIPAA regulations.
3. Load
The final phase transfers the cleaned and transformed data into the target destination.
Target Systems: Data warehouses (e.g., Amazon Redshift, Snowflake, Google BigQuery) or Data Lakes.
Loading Methods:
Full Load: Wiping and replacing all data in the target.
Incremental Load: Only loading new/updated data (the “delta”) to the target at regular intervals.
Automation: The process is typically automated to run during off-hours, ensuring the data is ready for morning reports.
Modern Trends and Tools
Cloud-Native ETL: Tools like AWS Glue, Azure Data Factory, and Google Cloud Dataflow allow for serverless, scalable data integration.
Reverse ETL: Moving transformed data from the warehouse back to operational systems (like Salesforce) to activate insights.
Streaming ETL: Processing data in real-time as it arrives, rather than waiting for batch updates, using tools like Apache Kafka.
DataOps: Applying DevOps principles (automation, testing) to data pipelines to ensure reliability and faster deployment.
When to Choose ETL vs. ELT
Choose ETL when: You need to comply with strict data security, perform complex transformations before data hits the warehouse, or have limited computing power in your target database.
Choose ELT when: You are using a cloud warehouse, dealing with massive unstructured data volume, or need high-speed ingestion.

Mark Whitfield involvement 2014 – 2015 :
In late 2014, I joined Betfred as a Senior IT Project Manager in the Gambling and Casinos industry delivering multiple projects for both Betfred online and mobile (iOS, Android and Windows) using the Agile SCRUM framework. Project deliveries covered payment gateways and methods, sportsbook for football and horse racing amongst others and the online virtual (computer generated) gaming components.
As a major part of this allocation, I also linked into Degree 53 for project/ app status and aid in the setting of priorities for their Betfred specific software delivery.

Projects varied in size and cost and extended over multiple phases requiring the management of many software suppliers, each delivering different aspects of the solution from fraud detection, frontend, middleware, payment services and mobile apps.
Agile Scrum is a widely adopted, iterative, and incremental framework designed to manage complex product development and software projects.
It breaks down large, daunting projects into small, manageable units called sprints—fixed-length iterations typically lasting 1–4 weeks—to deliver functional components faster and adapt to changing requirements.
Detailed Summary of the Scrum Framework
Scrum relies on three pillars—transparency, inspection, and adaptation—and is defined by specific roles, events, and artifacts.
1. The Scrum Team (Roles)
Product Owner (PO): Maximizes the value of the product by managing the Product Backlog. They define “what” is built.
Scrum Master: A servant-leader who helps the team follow Scrum theory and removes impediments.
Developers: The cross-functional team members responsible for creating the increment each sprint.
2. Scrum Events (Ceremonies)
Sprint Planning: Defines the Sprint Goal and the work to be done during the sprint.
Daily Scrum: A 15-minute daily meeting for developers to synchronize activities and plan the next 24 hours.
Sprint Review: Held at the end of the sprint to showcase the increment to stakeholders and gather feedback.
Sprint Retrospective: The team reflects on the process and identifies improvements for the next sprint.
3. Scrum Artifacts
Product Backlog: An ordered list of everything required in the product.
Sprint Backlog: The set of Product Backlog items selected for the sprint, plus the plan for delivering them.
Increment: The usable, working product increment produced at the end of a sprint.
Evolution of Scrum Over the Years
Scrum was developed in the early 1990s as a response to the failures of the linear “waterfall” approach.
1986 (Concept Origins): Takeuchi and Nonaka publish “The New New Product Development Game,” comparing traditional relay-race product development to a rugby “scrum” team.
1993 (First Implementation): Jeff Sutherland, John Scumniotales, and Jeff McKenna implement the first Scrum team at Easel Corporation.
1995 (Public Introduction): Ken Schwaber and Jeff Sutherland formalize Scrum and present “The Scrum Development Process” at the OOPSLA ’95 conference.
2001 (Agile Manifesto): Sutherland and Schwaber become signatories of the Agile Manifesto, cementing Scrum as a major Agile methodology.
2010 (The Scrum Guide): The first official Scrum Guide is released to standardize the framework worldwide.
2011–2017 (Refinements): The guide is updated to clarify roles and events, including strengthening the role of the Scrum Master and introducing self-organizing teams.
2020 (The Modern Scrum Guide): A major update makes the guide less prescriptive, focusing on a single Scrum Team (removing “development team” and “scrum team” split), introducing the Product Goal for long-term focus, and focusing on one team working towards one product.
