ETL in Data Mining 101: A Complete Guide

Businesses today are reliant on data to define their business goals. Hence, intelligent use of data, compute resources, and analytics approaches become essential. ETL in Data Mining is one such process that requires greater attention because, from a broader perspective, it can help improve performance and customer satisfaction rates, reduce risks, and much more.

But the question still stands: How can ETL in Data Mining help today’s organizations?

Companies have traditionally picked markets to focus on and assigned sales resources based on historical successes and gut intuition. Today, deep analytical skills, ETL processes, and Data Mining capabilities have enabled sales and marketing executives to make wiser judgments. Managers can now utilize data to accurately identify profitable micro markets and better coordinate sales resources to capitalize on newer possibilities. Companies that employ analytics to pursue a micro-market strategy significantly increase sales while paying less.

In this article, we will be discussing how data mining processes are objectified, and ETL and automated ETL in Data Mining is paving the way for real-time data analysis for greater profits margins.

Data Mining Processes Are Deployed For Specific Objectives

Data Mining — also termed Knowledge Discovery in Data (KDD) — is a pattern and information discovery process for large data sets. The process has been in operation to scuttlebutt, then infer new operations’ methodologies as answers to a few fundamental challenges organizations encounter as they scale.

With the advent of new cloud data warehousing technologies — hence the growth of big data — the rise of data mining has been obvious. That said, Data Mining can assist organizations in transforming raw data into business-crucial insights and help in scaling and automating business for the masses as technology evolves.

Data Mining can help improve decision-making and predict new market trends to nudge customers into the desired sales funnel. Here, the use of advanced analytics empowered by machine learning algorithms is crucial to driving desired understandings — from fraud mitigation to workflow bottlenecks detection, customer behavioral trends identification, and even when defining new data security paradigms.

On that note, a streamlined data mining process, according to IBM, looks like this: 

Underline Business Objectives > Data Preparation > Model Building & Pattern Mining > Result Acknowledgement & Implementation

Underline Business Objectives

The Data Mining process is objective-driven. Hence, the stakeholders must define a clear direction to optimize mining operations. On the other hand, additional research must be conducted from a data scientist’s perspective, too. Underlining business objectives is a vital first step in data mining operations, which must be conducted with an objective in mind.

Data Preparation

After defining the objective, data preparation is the next step. Data scientists identify important data sets to answer objectives defined in the previous step. Once the data sets are defined, its cleansed for quality purposes; hence a collection of relevant data is demarcated for further analysis. Additionally, from the performance point of view, one additional step is introduced to further disseminate information from data that is already present — this reduces the latency issues in the data mining process, which might arise and then cause slow computation.

Model Building & Pattern Mining

Data scientists may study any intriguing data relationships, such as sequential patterns, association rules, or correlations, depending on the sort of research. While high-frequency patterns have broader applicability, data variations can be more compelling at times, flagging areas of probable fraud.

Deep learning algorithms can also categorize or huddle a data collection based on the information provided. Suppose the input data is labeled (supervised learning). In that case, a classification model may be used to categorize the data, or a regression model can be used to forecast the likelihood of a specific assignment. Suppose the dataset is not labeled (unsupervised learning). In that case, the individual data points in the training set are compared to one another to uncover underlying commonalities, then clustered based on those similarities.

Result Acknowledgement & Implementation

After aggregating data, the results must be examined and interpreted. And when results are finalized, they should be legitimate, new, valuable, and clear. Companies must utilize this information to adopt new strategies and achieve their goals when this criterion is satisfied.

What is ETL?

ETL — Extract, Transform, and Load — is a process in Data Warehousing that helps data professionals to extract data from many various source systems, transform it into structured data sets, and then load it into a data warehouse of your choice

ETL in Data Mining

ETL works as a facilitator in the Data Mining process. And as mentioned above, Data Mining is the art and science of extracting relevant data from the pool of relevant data sets for further analysis to gain a competitive advantage.

That said, it’s crucial to understand the role of the Cloud in the Data Mining industry, too. Because, ultimately, the ETL process is cloud-dependent. On the other hand, Data Mining requires relevantly extracted, transformed, and loaded data to make sense of specific business nuances that are either hard to understand or not visible due to the sheer volume of data present. 

To better understand the role of ETL in Data Mining, let’s draw an inference from a research paper, “Cloud Data Mining and Analytics: Bringing Greenness and Acceleration in the Cloud,” published in April 2021.

Look at the figure given below.

The figure depicts a holistic architecture for data mining and machine learning using the technologies like Graphic Processing Unit, Approximate Computing, Quantum Computing, and Nural Processing units — and at the crux, is the Cloud. Seen at the outermost ring is a combination of big data (data) and machine-learning-related algorithms and tasks for the user to invoke.

Let’s talk more about the Cloud, which, in the research article, is termed “the cloud paradigm.” The Cloud represents the cloud service users. These users analyze and use data for “learning purposes” — which in our case, will get used to optimize business processes for competitive advantage in micro-markets.

“Data mining,” the paper defines, “is the mining of data or discovery of knowledge from structure, semi-structured unstructured data.” And “Data analytics,” the paper defines, “the process of extraction, cleaning, transforming, modeling, and visualizing the data to find meaningful information and further draw inferences and conclusions out of it.” 

The above statements help us understand the importance of ETL as a facilitator in the data mining process. Because ultimately, users must load the data from one source to another. Now, the ETL in Data Mining becomes integral. And, with the introduction of new ETL technologies, like automated ETL pipelines, the process has become much more accessible and cost-effective, which earlier was not the case. Furthermore, data needs to be analyzed for business intelligence purposes after the data mining process is completed.

Automated ETL in Data Mining

As your data repositories in the cloud increase, the need for more computing and processing power grows; hence, the want for an ETL data pipeline becomes evident in Data. Here, a best practice must exist. A shift should happen from legacy computing and data transformation techniques to more viable methods using a cloud or cloud-like setup for real-time enterprise data analysis.

Using a cloud-like setup, the processing power required to mine data and then transform it into an analysis-ready format becomes more accessible. Cloud computing uses on-demand computing resources like compute nodes, network infrastructure, and other services to construct data mining and related tasks. The data mined using these techniques is complete and comprehensive.

On the other hand, an automated ETL in Data Mining can be tricky, requiring periodic modification and coding competencies. Using automated ETL tools like Hevo, data professionals can quickly design data pipelines to monitor real-time changes in a user-friendly manner. Moreover, automated ETL tools have many advantages as connectors’ lists are already present, making data transfer routines much faster and agile at the same time.

Conclusion

To conclude, ETL in Data Mining is still in a developing stage. It’s a great new domain to pursue, but it’s not something you can learn without a thorough study of math and algorithms.

Data mining typically entails using data from integrated sources to infer information from transactional data that would not, in some cases, be obvious. Hence, it’s typically focused on using a large amount of data to predict future answers or better understand patterns in the existing data sets.
