Change log

Roadmap for this book, I will update it as I go.

Release #1: Introduction, Basic Skills, Hands-On Insights, Mock Interview Question and practical answers, Data Camping Package.
Release #2: Advanced Skills.

2025-01-14

Revise the Data Structures and Algorithms and reflect the data engineering works with DSA
Update the mermaid chart with white colo background.
Add the Mock Interview Question and practical answers section to let you into the real interview questions which I most used when I was a Data Engineering Interviewer and of course I also was a Data Engineering Interviewee.

Add Data Processing Practices section which covers common data processing problems that arise in data engineering and how to solve them with basic data processing techniques.

Update Data Camping - Week 8 Data Orchestration and Automation section, included the review of how to automate data development process. As we have learned Containerization from previous weeks and practiced it for a while, this is the time to review and starting to explore the xOps area.
Update Data Camping - Week 9 Capstone Projects with the curated list of project of side-development, discovering space and other community project.
In the Capstone project: we emphasize the consideration when you want to develop somethings that depends on business need. Otherwise, It is the technology discovery or POC, learning curve.
I also mention about What is your responsibilityonsibility according the Scrum project. Follow the Seniority Levels and the Responsibility Matrix.
I hope this 2 sections for closing the camping will help you to understand the concepts and the practices of Data Engineering and extend next more weeks, months, and years to be a better data engineer.

Updating How Data Pipeline Structured section
Discovering that multi-hop architecture is a common pattern in data warehouse and data pipeline.
Trying to understand the pros and cons of each patterns included the 3 types of data pipeline design.

Adding Data Structures and Algorithms section and how it related to Data Engineering.
This section covers the fundamentals of data structures and algorithms, including arrays, linked lists, hash tables, trees, graphs, stacks, queues, and dynamic programming.
Also, I added the visualization, but it is limited of course, but I hope it will help you to understand the concepts.

Adding Cloud System Understanding section
This section provides a comprehensive guide on how to start with cloud technologies
Covering the fundamentals of cloud computing, including different service models (IaaS, PaaS, SaaS), Introduction to major cloud providers
Overview of key cloud services essential for data engineering: storage, compute, and database services
Best practices for how to get starting with Cloud.

Adding Week 7 Data Quality
This is the essential part in any data engineering project as the MUST HAVE item. Good Data is Better Than Big Data.
How to use data quality in data warehouse and data pipeline; e.g: Snowflake and dbt. I experience with Deequ and implement that into Spark Job.
Adding Common Components for Analytics Platform and how Data Architecture looks in real-world. That helps you understand the daily works of Engineers who works on data industry.

Add Week6 of Data Engineering: Streaming with Kafka, Kafka use cases, Simple Kafka EcoSystem, etc.
I mention about thinking process to resolve the problem of streaming data with Kafka.
Add the Deep Work section in How to Read.
Add Scope of Data Engineer & Better Data Engineer

Update Basic content, Updated Analytics Platform, Updated Data Achitecture Design
I have added a subscription option for half of part two and whole part three. This was a difficult decision for me, as I genuinely want to share everything I write with all of you, you can check the blogs site. However, I must acknowledge the significant amount of time and effort I have invested in compiling and distilling my free resources into this comprehensive book.
If you find value in this book, I believe the small subscription fee is justified to ensure you receive the latest, up-to-date content in data engineering. I apologize if this decision disappoints anyone. This also allows me to dedicate more time to this book and my writing in general.
For more details, please visit the subscription page. Additionally, I have updated the copyright and legal notice, as well as the privacy policy, to reflect the technology used for managing subscriptions.
Furthermore, I am going to pack all the ebook into single package so that you can checkout and download it. Your support always meaningful with me. Thanks
