For freshmen in any knowledge discipline, it’s typically powerful to actually perceive what a selected knowledge discipline is about. You’ll be able to learn theoretical explanations and job descriptions and hearken to YouTube movies explaining them, however your understanding all the time stays at that I-get-it-but-not-quite degree.
The identical is true with knowledge engineering. In fact, it’s worthwhile to know what knowledge engineering is and what knowledge engineers do. And we’ll begin with that. However it’s best to complement this theoretical information with observe; at their intersection lies actual information.
Practising knowledge engineering is kind of troublesome with out truly working at an organization as a knowledge engineer. That is primarily as a result of knowledge engineering shouldn’t be solely about dealing with knowledge but in addition about knowledge structure and constructing knowledge infrastructure.
Nonetheless, there’s a approach, and the best way is doing knowledge engineering tasks. Figuring out what knowledge engineers do will assist us choose appropriate tasks for mastering knowledge engineering.
What’s Information Engineering?
Information engineering ensures knowledge flows – in batches or in real-time – from a number of and numerous knowledge sources to knowledge storage, the place it’s obtainable to knowledge customers. In between, knowledge can be processed, analyzed, and remodeled right into a format appropriate to be used.
That is referred to as a knowledge pipeline, and the info engineer’s job is to construct and keep it.
From that description, we are able to extract essential elements of knowledge engineering:
- Information transformation & processing
- Information visualization
- Information pipelines
- Information storage
To grasp knowledge engineering, your tasks ought to give attention to or embrace a few of these matters.
Because of the nature of knowledge engineering, it’s unattainable to think about a challenge that may cope with just one facet of it; such is the wholesomeness of a knowledge engineer’s job. It isn’t actually doable to do a challenge that solely does knowledge processing – OK, however the place does this knowledge come from, and the place does it finish?
So, most tasks I’ve chosen are end-to-end knowledge engineering tasks that may train you how one can construct a knowledge pipeline – the essence of knowledge engineering. Nonetheless, the tasks take totally different approaches and totally different applied sciences, so there are some elements you’ll be able to study from one challenge that you would be able to’t study from one other.
Information Engineering Undertaking Concepts

Doing tasks teaches you what knowledge engineering is in observe. To finish a challenge, you have to present numerous technical abilities, familiarity with widespread knowledge engineering instruments, and an understanding of the entire course of.
This makes tasks perfect for studying.
1. Information Pipeline Growth Undertaking
You don’t get extra knowledge engineering than constructing a knowledge pipeline. Making certain knowledge circulate from its sources to knowledge customers and, by extension, supporting data-driven decision-making is on the coronary heart of knowledge engineering.
By doing a knowledge pipeline growth challenge, you’ll find out about integrating knowledge from numerous sources and the entire ETL course of.
Undertaking Suggestion
Hyperlink: AWS Finish-to-Finish Information Engineering by CodeWith You (Yusuf Ganiyu)
Description: This is a superb challenge whose aim is to construct a knowledge pipeline that may extract knowledge from Reddit, rework it, after which load it into the Redshift knowledge warehouse.
The video guides you thru each step, and the challenge’s supply code can be obtainable on GitHub.
Applied sciences Used:
2. Information Transformation Undertaking
Reworking knowledge means it’s turned into standardized codecs appropriate with analytical instruments and appropriate for evaluation.
Other than enabling knowledge evaluation and decision-making, knowledge transformation additionally has a significant function in enhancing knowledge high quality, because it entails cleansing and validating knowledge.
Undertaking Suggestion
Hyperlink: Chama Information Transformation by StrataScratch
Description: The task right here is to rework Chama’s knowledge present in three .csv recordsdata utilizing whichever programming language you need however following particular transformation guidelines.
Applied sciences Used:
3. Information Lake Implementation Undertaking
Information lakes are central repositories that retailer massive quantities of knowledge of their unique format. They’re important for dealing with and analyzing large knowledge. As large knowledge turns into extra widespread in enterprise, knowledge engineers should know how one can implement knowledge lakes.
Undertaking Suggestion
Hyperlink: Finish-to-Finish Azure Information Engineering by Kaviprakash Selvaraj
Description: This Azure Information end-to-end knowledge engineering challenge makes use of gross sales knowledge. It covers matters equivalent to knowledge ingestion, processing, and storing. What makes it attention-grabbing is that it outlines the steps for organising and managing a knowledge lake, particularly Azure Information Lake.
Applied sciences Used:
4. Information Warehousing Undertaking
Information from knowledge lakes is structured after which saved in knowledge warehouses. These function central knowledge repositories for enterprise intelligence.
Implementing a knowledge warehouse makes knowledge retrieval extra environment friendly and simplifies knowledge administration, together with guaranteeing knowledge high quality and enabling insights into knowledge.
With a knowledge warehousing challenge, you’ll find out about knowledge modeling and database administration.
Undertaking Suggestion
Hyperlink: AWS Information Engineering Undertaking by Ahmed Ali
Description: This end-to-end challenge makes use of NYC taxi knowledge with the aim of constructing an ELT pipeline in AWS. It’s appropriate for studying knowledge warehousing since knowledge is loaded in a knowledge warehouse, particularly, Amazon Redshift.
Applied sciences Used:
5. Actual-Time Information Processing Undertaking
Processing knowledge in real-time has grow to be more and more essential for companies to make well timed and proactive selections. Due to that, knowledge engineers should know how one can arrange a system that may successfully and effectively course of knowledge in real-time.
Undertaking Suggestion
Hyperlink: Actual-Time Information Streaming by CodeWithYu (Yusuf Ganiyu)
Description: This CodeWithYu video offers you detailed steering on constructing a pipeline for knowledge streaming. You’ll discover ways to arrange a knowledge pipeline, stream it in real-time, distributed synchronization, knowledge processing, knowledge storage, and containerization.
The information you’ll work with is generated by the randomuser.me API. Like in certainly one of his movies I linked earlies, this one additionally has a supply code on GitHub.
Applied sciences used:
6. Information Visualization Undertaking
Whereas knowledge visualization may not be the very first thing that involves thoughts when fascinated with knowledge engineering, it is a vital talent for knowledge engineers.
Visualizing knowledge within the context of knowledge engineering normally means creating operational dashboards that present the present state of knowledge pipelines, e.g., the processing pace or the quantity of knowledge ingested.
Information engineers may create dashboards for knowledge saved in a warehouse to assist enterprise customers get the data they want simpler.
Undertaking Suggestion
Hyperlink: From Uncooked to Information Visualization – Information Engineering Undertaking by Naufaldy Erianda
Description: The aim of this challenge is to extract knowledge from numerous sources, rework it, and make it obtainable for knowledge visualization. In the long run, you’ll create a dashboard in Looker Studio.
Applied sciences used:
Conclusion
Information engineering is a fancy discipline which may appear overwhelming, particularly to freshmen. The simplest to begin actually understanding what knowledge engineering is all about is by doing knowledge engineering tasks.
I instructed six tasks that may train you:
- Constructing a pipeline
- Rework knowledge
- Implement knowledge lake
- Implement knowledge warehouse
- Construct a pipeline for real-time knowledge processing
- Visualize knowledge
Machine studying is more and more turning into important for automating numerous knowledge engineering duties. So, to not be left behind, take a look at a few of these machine studying tasks and knowledge science tasks that may also be used to observe knowledge engineering abilities.
