If you know how important data mapping can be to our future with big data, this information is exactly what you’ll need. The guide provides the steps to understanding the concept of data mapping and how it works, using various instruments and methods to map data that will yield high-quality results. In this article, we’ll explore the notion of Data Integration and data mapping and explain its purpose, importance, and how it’s carried out.

What Is Data Mapping?

It refers to linking data fields of various sources together. As per the definition of data mapping, for example, the healthcare industry might have data about patients in a database stored on the server. They must share this information with their billing software to ensure that staff cannot duplicate hundreds of names, addresses, and other details. A company will create an outline of the data map, which outlines the location of data, where it goes, how it arrives there, and any changes that might be required during the process. This way, the data mapping process allows users to share data across different sources automatically.

When you create a data map, you receive a graphic representation of how data travels and any modifications to its format or contents. Data mapping is typically the initial step that brings data from multiple sources into a unified destination. This helps you identify your path to integrating data and address security and compliance issues. Mapping data fields minimizes the chance of errors and helps to promote data standardization. It clearly shows how data points can be linked, such as how maps help users navigate from one location to another. Data mapping errors can be a severe problem for crucial projects needing data management.

Data mapping helps you comprehend data transformation and movement. It’s an essential element of the complete data integration procedure, wherein data collected from various sources is merged into one place. With data becoming increasingly numerous and complex in the present business climate, sophisticated and automated methods are essential to successful data mapping.

Why Is Data Mapping Important For Modern Businesses?

When organizations create and utilize ever-growing amounts of data, they must minimize the chance of making mistakes. However, they must also increase their capabilities to draw information, which could require many different data types. Data mapping allows organizations to benefit from both worlds. The visualization capabilities of data mapping ease the process of mixing data and do not force users to limit the number of sources from which they draw data or how they use the data.

Additionally, by mapping and standardizing data you gather from various systems, it becomes simpler to comprehend the relationship between it and your goals for business regardless of where the data is stored or from the source. For business analysis and intelligence, Data mapping is an essential function. Data mapping can help you get a top-level understanding of the data your company requires to utilize to reach its goals for growth. Additionally, it makes the data’s context more straightforward to understand. The mapping process eliminates the need to investigate the systems that created each data item. Instead, you can focus on the use of it to gain information. Data mapping is crucial to understanding customers’ and employees’ behavior and thinking. It opens the door to connecting data from various sources, allowing you to understand individuals’ behavior, decisions, and performance.

Use Cases For Data Mapping

Data mapping offers an organized method of managing data. Below are a few of the more popular mapping applications for organizations.

Data Migration

It transfers information between various storage systems used by different computing systems. By mapping the data flow between databases, it is possible to transfer critical business data between multiple systems seamlessly. Most companies expect a non-code data mapping program to perform any move seamlessly. One example is that one of the most popular types of data migration is transferring on-premise data into the cloud during the digital change.

Data Integration

Data integration is the act of combining data in one place. Data mapping plays a crucial role in integration. It is the connection between the two or more systems using the data. Data Integration Solutions will only be efficient if the source of data and the repository’s structure are appropriately mapped.

In this case, the retailer can integrate information between the mobile app and its website. When a consumer buys something like a product, the amount they spent and the time they made are stored in the backend on the website’s e-commerce platform. The information is then connected to the mobile app. It offers discounts or deals in line with their purchase history. The company’s engineering team would use data mapping to identify the data sources and what to do with the data so that the mobile app’s backend could utilize the information.

Data Transformation

It refers to the process that converts a data format from one to an alternative format. It is a primary process of transforming data to a desired format. Often referred to as extract/transform/load (ETL), this process usually involves some degree of data cleaning, validation, or enrichment. Data transformation can be challenging to implement into a mapping tool; however, some tools simplify the process. 

Data Warehousing

As they build and maintain databases, data scientists utilize data mapping to ensure that data enters the warehouse and is delivered as it demands.

Electronic Data Interchange (EDI) Exchange

Electronic data exchange (EDI) is the process of two or more organizations exchanging documents using electronic methods. Data mapping plays a significant function in the EDI conversion of files because it determines which information diverse entities exchange, the locations where the data is shared, and how it is transferred.

Privacy Regulations

Data mapping is essential in ensuring that companies are compliant with data compliance requirements. Businesses use it to ensure that sensitive data isn’t disclosed to the wrong individuals or the bad systems.

Process Of Data Mapping

In mapping data, you begin by understanding what information you have and how you intend to utilize it. It is also important to identify the sources of the data and their intended destination, as well as how these data are linked in your technology stack.

Find The Information Needed To Be Transferred, Moved, And Transformed

The first step in all methods of mapping data is determining the data that needs to be moved to a different place. This is a straightforward but crucial step because it allows you to define what fields and tables require moving and in what format the data has to be transferred in the aftermath of the move. The amount of data mapping transferred and the process used for mapping are also factors to consider during this stage.

Data Mapping

The process of mapping data involves setting up the data flow by mapping the information from the source to the final destination and storing the process logs. In the case of higher data volumes or frequencies, the semi-automated or automated method is better than manual mapping.

Transform The Information

This is where the data’s format is altered to conform with the standard and limitations on the format of the data destination. This transformation helps to save and utilize the field efficiently.

Testing And Deployment

Data converted after transformation must be validated and examined using manual, semi-automated, or automated procedures. When data is more extensive, most organizations use automated testing methods or tools for automated testing. Once testing is completed and data has been gathered, it can be transferred for use in its applications. It could include moving data into databases for business intelligence or analytics.

Maintain Data Maps Over Time

Data maps need periodic updates and maintenance to meet businesses’ ever-changing demands. When data maps, associated apps, and sources change over time, any adjustments should be recorded, and Integrated Data Systems should be added to the data map.

Data Mapping Techniques

The methods are based on how you intend to utilize the information and the size of the initiative.


Manual data mapping occurs when the company codes its data map in-house. This usually involves handwriting lines of code or using tools pre-written in code libraries. Coding languages commonly employed include SQL, C++, and Java. The latter requires the greatest effort but also allows for the greatest control.


When using semi-automated data mapping, companies can balance flexibility and efficacy. Certain parts of the data mapping process can be automated, and others can be coded manually. The most common method for semi-automated data mapping processes is to use visual or graphic representations of the data. Although it has many advantages, it is essential to remember that semi-automated data mapping requires coding knowledge and technical expertise to distinguish between manual and automated data mapping.


A computerized approach can be done without the knowledge of coding experts. The map can be created according to the user’s proficiency level, and an automated system can make connections using their instructions.
