What is data transformation?

The data needs to be adjusted or cleaned up to make this information work well together so that everything matches. Sometimes, data from various places may look different. Data transformation helps to make all the information look the same, allowing it to be compared or combined easily. This is important for tasks like analyzing information, which businesses use to make data-driven decisions.

Data transformation also involves changing the structure of data. For instance, a list of names might be turned into a table, or words might be converted into numbers so that computers can understand and work with them more effectively. This process makes the data more useful for specific tools or programs. When data is moved from one system to another, data transformation ensures it fits properly in the new system. This helps to keep the information accurate and ready for use.

In essence, data transformation is about making raw information clean, clear, and prepared for any task it needs to perform. This process is important for businesses to succeed. EY research reveals that one of the biggest reasons companies struggle with transformation is because they don’t place enough value on trustworthy data. Furthermore, McKinsey has shown that organizations can reduce their IT costs and investments by up to 30% if they simplify their data architecture and reduce data fragmentation.

What are the key steps involved in data transformation?

Understanding the key steps in data transformation is important for knowing how raw data becomes useful information. Each step helps ensure the data is correct, consistent, and ready to use. These steps allow companies to prepare the data, making it easier to compare, combine, and understand. They ensure that the data is clean, in the right format, and has all the necessary details. Let’s look at the key steps that make data transformation work well.

Cleaning the data

To ensure the data is correct, mistakes are fixed, duplicates are removed, and missing information is filled in.

Making data consistent

Changing data to a common scale or format so that it’s easier to compare and use together.

Summarizing data

Combining data from different places into a simple format, like finding the average or total.

Adding extra information

Enhancing the data by including more details, like adding location information to customer records.

Changing the format

Converting data from one type to another, like turning words into numbers.

Putting the changed data into a new system or tool so it’s ready to use.

Data transformation vs data cleaning

Data transformation and cleaning help prepare data for use, but they perform different actions.

• Data transformation changes how the data is organized or formatted to fit what’s needed.
• Data cleaning fixes mistakes and removes duplicates to ensure the data is correct.

Let’s look at how these two steps differ and how they each help make data useful.

	Data transformation	Data cleaning
Definition	Changing data into a different format or structure so it can be used better.	Fixing mistakes in the data and removing any errors or duplicates to make it correct.
Focus	Changing the data’s shape or format to fit what’s needed.	Making sure the data is accurate and has no errors.
Techniques	Changing the data’s format Combining data Adding extra information	Finding and fixing mistakes Removing duplicates Filling in missing information

Examples of use	Changing sales data from different sources into the same format so it can be analyzed together.	Removing repeated customer entries from a list ensures the data is accurate.

Use cases for data transformation

Data transformation is important in different business situations. Whether it’s organizing sales data to make reports, merging customer information to improve marketing, or combining inventory data for better management, data transformation makes it more useful. It can be difficult to see how this works in practice, so here are three examples of how data transformation helps in different business settings.

Sales reporting

Sales data from different regions often arrive in various formats, such as differing date styles and currency symbols. Data transformation processes convert these diverse formats into a standardized form to ensure consistency, allowing the data to be combined and analyzed collectively. This standardization is crucial for creating clear and comprehensive sales reports, enabling businesses to compare and assess sales performance across all regions.

Customer insights

Customer information is collected from various sources, including websites, social media, and in-store purchases. Data transformation processes consolidate this information into a cohesive format and enrich it with additional details. This integration and enhancement of customer data give businesses a clearer and more comprehensive understanding of their customers, enabling more effective marketing strategies and personalized customer interactions.

Inventory management

Inventory data is often recorded in different systems, each using various formats. Data transformation processes standardize this information into a consistent format and consolidate it into a central repository. This uniformity allows businesses to track stock levels and manage supplies more accurately, leading to improved efficiency in inventory management and better decision-making.

What are the advantages of data transformation?

Transforming data has many benefits that help businesses use information better. By changing data into a clearer and more organized format, companies can ensure accuracy, work faster, and keep data safe. This helps in making smarter decisions and managing data more easily. Let’s look at the main advantages of data transformation and how it can improve business.
