For newbies in any information discipline, it’s usually powerful to actually perceive what a selected information discipline is about. You’ll be able to learn theoretical explanations and job descriptions and take heed to YouTube movies explaining them, however your understanding all the time stays at that I-get-it-but-not-quite stage.
The identical is true with information engineering. After all, it’s essential know what information engineering is and what information engineers do. And we’ll begin with that. However you must complement this theoretical data with follow; at their intersection lies actual data.
Training information engineering is sort of troublesome with out really working at an organization as an information engineer. That is primarily as a result of information engineering just isn’t solely about dealing with information but additionally about information structure and constructing information infrastructure.
Nevertheless, there’s a manner, and the way in which is doing information engineering tasks. Understanding what information engineers do will assist us choose appropriate tasks for mastering information engineering.
What’s Knowledge Engineering?
Knowledge engineering ensures information flows – in batches or in real-time – from a number of and numerous information sources to information storage, the place it’s out there to information customers. In between, information can also be processed, analyzed, and remodeled right into a format appropriate to be used.
That is known as an information pipeline, and the info engineer’s job is to construct and keep it.
From that description, we are able to extract essential features of knowledge engineering:
- Knowledge transformation & processing
- Knowledge visualization
- Knowledge pipelines
- Knowledge storage
To grasp information engineering, your tasks ought to give attention to or embrace a few of these matters.
Because of the nature of knowledge engineering, it’s inconceivable to think about a mission that can cope with just one facet of it; such is the wholesomeness of an information engineer’s job. It isn’t actually potential to do a mission that solely does information processing – OK, however the place does this information come from, and the place does it finish?
So, most tasks I’ve chosen are end-to-end information engineering tasks that can educate you tips on how to construct an information pipeline – the essence of knowledge engineering. Nevertheless, the tasks take totally different approaches and totally different applied sciences, so there are some features you possibly can study from one mission which you can’t study from one other.
Knowledge Engineering Challenge Concepts

Doing tasks teaches you what information engineering is in follow. To finish a mission, it’s essential to present numerous technical expertise, familiarity with widespread information engineering instruments, and an understanding of the entire course of.
This makes tasks ideally suited for studying.
1. Knowledge Pipeline Growth Challenge
You don’t get extra information engineering than constructing an information pipeline. Guaranteeing information circulation from its sources to information customers and, by extension, supporting data-driven decision-making is on the coronary heart of knowledge engineering.
By doing an information pipeline growth mission, you’ll study integrating information from numerous sources and the entire ETL course of.
Challenge Suggestion
Hyperlink: AWS Finish-to-Finish Knowledge Engineering by CodeWith You (Yusuf Ganiyu)
Description: This is a wonderful mission whose objective is to construct an information pipeline that can extract information from Reddit, rework it, after which load it into the Redshift information warehouse.
The video guides you thru each step, and the mission’s supply code can also be out there on GitHub.
Applied sciences Used:
2. Knowledge Transformation Challenge
Remodeling information means it’s become standardized codecs appropriate with analytical instruments and appropriate for evaluation.
Other than enabling information evaluation and decision-making, information transformation additionally has a significant function in bettering information high quality, because it entails cleansing and validating information.
Challenge Suggestion
Hyperlink: Chama Knowledge Transformation by StrataScratch
Description: The task right here is to rework Chama’s information present in three .csv information utilizing whichever programming language you need however following particular transformation guidelines.
Applied sciences Used:
3. Knowledge Lake Implementation Challenge
Knowledge lakes are central repositories that retailer massive quantities of knowledge of their authentic format. They’re important for dealing with and analyzing large information. As large information turns into extra widespread in enterprise, information engineers should know tips on how to implement information lakes.
Challenge Suggestion
Hyperlink: Finish-to-Finish Azure Knowledge Engineering by Kaviprakash Selvaraj
Description: This Azure Knowledge end-to-end information engineering mission makes use of gross sales information. It covers matters equivalent to information ingestion, processing, and storing. What makes it attention-grabbing is that it outlines the steps for establishing and managing an information lake, specifically Azure Knowledge Lake.
Applied sciences Used:
4. Knowledge Warehousing Challenge
Knowledge from information lakes is structured after which saved in information warehouses. These function central information repositories for enterprise intelligence.
Implementing an information warehouse makes information retrieval extra environment friendly and simplifies information administration, together with guaranteeing information high quality and enabling insights into information.
With an information warehousing mission, you’ll study information modeling and database administration.
Challenge Suggestion
Hyperlink: AWS Knowledge Engineering Challenge by Ahmed Ali
Description: This end-to-end mission makes use of NYC taxi information with the objective of constructing an ELT pipeline in AWS. It’s appropriate for studying information warehousing since information is loaded in an information warehouse, specifically, Amazon Redshift.
Applied sciences Used:
5. Actual-Time Knowledge Processing Challenge
Processing information in real-time has turn out to be more and more essential for companies to make well timed and proactive selections. Due to that, information engineers should know tips on how to arrange a system that can successfully and effectively course of information in real-time.
Challenge Suggestion
Hyperlink: Actual-Time Knowledge Streaming by CodeWithYu (Yusuf Ganiyu)
Description: This CodeWithYu video offers you detailed steerage on constructing a pipeline for information streaming. You’ll learn to arrange an information pipeline, stream it in real-time, distributed synchronization, information processing, information storage, and containerization.
The information you’ll work with is generated by the randomuser.me API. Like in one in every of his movies I linked earlies, this one additionally has a supply code on GitHub.
Applied sciences used:
6. Knowledge Visualization Challenge
Whereas information visualization may not be the very first thing that involves thoughts when enthusiastic about information engineering, it is a crucial talent for information engineers.
Visualizing information within the context of knowledge engineering normally means creating operational dashboards that present the present state of knowledge pipelines, e.g., the processing velocity or the quantity of knowledge ingested.
Knowledge engineers might also create dashboards for information saved in a warehouse to assist enterprise customers get the knowledge they want simpler.
Challenge Suggestion
Hyperlink: From Uncooked to Knowledge Visualization – Knowledge Engineering Challenge by Naufaldy Erianda
Description: The objective of this mission is to extract information from numerous assets, rework it, and make it out there for information visualization. Ultimately, you’ll create a dashboard in Looker Studio.

Conclusion
Knowledge engineering is a posh discipline which may appear overwhelming, particularly to newbies. The simplest to start out actually understanding what information engineering is all about is by doing information engineering tasks.
I instructed six tasks that can educate you:
- Constructing a pipeline
- Remodel information
- Implement information lake
- Implement information warehouse
- Construct a pipeline for real-time information processing
- Visualize information
Machine studying is more and more changing into important for automating numerous information engineering duties. So, to not be left behind, have a look at a few of these machine studying tasks and information science tasks that may also be used to follow information engineering expertise.
