Components of Data Science

3 Mins read

Finding patterns in data is the essence of data science. These patterns can be utilised to get business knowledge or to develop new product features. Both of these products of a data science study may help product teams distinguish their offers and give more value to consumers. Before using data science, one should be well knowledgeable in the domain’s basic components. The definitions of these phrases may vary, but in general, this should help you grasp certain fundamental ideas.

      Data Strategy

      Data Engineering

      Data Analysis and Models

      Data Visualization and Operationalization

Data Strategy

Making a data strategy is as simple as deciding what data to collect and why. Despite its obviousness, it is frequently neglected, undervalued, or unformalized. To be clear, we are not discussing the method for selecting mathematical approaches or technology. The other issues are significant, but not the initial step.

To choose a data strategy, you must first assess its relevance to your company’s goals. Gathering data, presenting it appropriately, and deleting “garbage” data that doesn’t serve your company’s goals will take time and effort. Your team will identify data that is vital to your company goals and so worth collecting and sorting. So if gathering new data takes a lot of time and effort, it may not be worth collecting.

Data Engineering 

Data Engineering is the use of technology and systems to access, organise, and utilise data. It includes creating software to solve data difficulties. These solutions often start with a data system and then add data pipelines and endpoints to it. This can include hundreds of technologies, typically on a massive scale. 

Data science is impossible without data engineering. Finally, data engineering allows data to flow from the product to other stakeholders. You can’t design an algorithm to optimise image scheduling until the device’s data can reach the person or “bot” who will study it and offer recommendations. Data “plumbing” is what engineering is all about.

To comprehend the distinction between data analysis and data engineering, consider the abilities of a data engineer. A data engineer is a superior coder and a specialist in distributed systems. An awareness of data technologies and frameworks is required, as is the ability to mix them to develop solutions that support business operations.

Data Analysis and Mathematical Models 

Much of what we connect with data science happens here. We collect data and use Math or an algorithm to model a “system’s” actions (perhaps both). Data analysis and mathematical modelling encompasses the following:


      Math & Statistics

      a domain (like healthcare)

      The scientific process & features of it.

To further simplify, we conceive of data analysis and mathematical models as follows:

      To describe, analyse, or forecast a service, product, person, business, or technology (or a mix of them)

      Create a “tool” that substitutes or supplements human actions

    Most machine learning does this — plays Go, reads X-rays, schedules patients. It substitutes a human “thinking about” and completing a task, not a mechanical robot putting in lug nuts.

A model is created to make a prediction using data. This is what science has always done. The second use case pertains to what engineers have traditionally done with math and science: design a technology that supports or outperforms a human.

New in data analysis and mathematical modelling include computer power, data volume, and inventive methodologies. Due to limits in processing capacity, we have only lately been able to expand on existing mathematics and statistics.

Visualization and Operationalization

We integrated operationalization and visualisation since they are usually used together. However, operationalization is a more general idea. With the information in hand (after analysis and modelling), you will reach a judgement or take action based on the analysis and modelling. Statisticians use graphs to display statistics or evaluate data while making decisions rather than “bots.” The rationale is simple: visualisation is typically the quickest and most efficient way to communicate the significance of data or analysis to the person understanding data science results.

Data Visualization

Visualization is more than merely displaying data analysis results “correctly.” With the help of the operations team, it is occasionally essential to delve back into the raw data and determine what should be shown.

Your team will need to understand the following principles to connect to the present ecosystem and stand out in the market among competitors if you are designing a data visualisation device.

      How will the data be used?

      The data consumer’s demands and skills.

      Users’ physical position, devices, physical surroundings, and situational context.

      The analysis complexity.

Data Operationalization

Operations research is about doing something with data; someone (or, occasionally, a machine) has to make a decision and/or take action based on the calculations. This might be in the form of:

      A live person’s decision/action.

      Long-term reaction.

      A task-specific suggestion.

Use this tool to describe what data you want to gather and why, as well as how the data will be used to improve or alter a system. This will logically lead to data strategy, data engineering, etc.

If you don’t want to create an ecosystem, you can use your present method for defining and developing other product features. But, based on our experience, we strongly urge you to try it. Consider adopting data science as if you were creating a new product feature, since that is precisely what it is.
