The 5 Key Data Mapping Steps
Now, it’s time to unravel the process of data mapping and share our data mapping strategy. We’ve created a step-by-step guide to make this journey as smooth and errorless as possible. However, keep in mind that there’s no one-size-fits-all recipe for data mapping: feel free to adjust these steps and processes to your unique needs and capabilities. How to do data mapping, then?
Identify All Data Fields That Must be Mapped
First things first – identify which information needs to be moved or restructured. Depending on what you want to accomplish with mapping, there are three ways to go:
- Integration. Assess how much information needs to be combined, where the information comes from, how many information sources there are, and how often the integrations will happen. If the integration appears to be large and more frequent, there’s a need for an automated tool. If it’s a one-time project that does not require much effort and time, it can be done manually.
- Migration. In this case, look at the source information and think of what you need in the target location. The quantity of information will help you identify the needed approach: the bigger the amount of information – the higher the need for automated software for mapping data.
- Transformation. Here, you need to identify the format you want your information to reach the final destination in. In most cases, such transformations require automation tools. However, small projects might be performed manually.
Standardize Naming Conventions Across Sources
The next step involves identifying the format of information in each of your information sources. Once you have this information, define the format you need for the target information. Standardizing naming conventions across all information sources ensures consistency and avoids confusion during the mapping process.
Create Data Transformation Rules and Schema Logic
This step depends on how you map your information:
- Automated. Here, you can rely on the drag-and-drop UIs to handle all the hard work for you. Even your non-technical employees will be able to map out complex information in minutes without the need to code.
- Semi-automated. You can use your software to create connections between information sources and their destinations. One it is done, work with an experienced developer or information scientist who will check if everything is working correctly and smoothly.
- Manual. You can hire an experienced software developer to code the rules and schemas that map your information.
Test Your Logic
Before completing the migration, integration, or transformation, thoroughly test your information transformation logic. Run test scenarios to validate that the mapping rules work as intended and that the information is accurately transformed and integrated. Testing helps identify and resolve any issues or errors before the final implementation. You can also manually check a small amount of information in your integration, migration, or transformation to ensure that everything is working flawlessly.
Complete the Migration, Integration, or Transformation
After successfully testing your logic, proceed with the complete information migration, integration, or transformation process. Use automated tools where necessary to streamline the process and minimize errors. Ensure continuous monitoring and validation throughout the process to maintain information quality and accuracy.
Data Mapping Challenges
Despite the incredible benefits of mapping, it has its challenges that you should be aware of. It’s better to come prepared and be ready to face these challenges fully armed than let them affect your processes.
- Data Heterogeneity. Information comes from various sources, each having its own information format, conventions, and structures. Mapping data that comes from diverse sources can be challenging because of the inconsistencies and differences in information representations.
- Data Volume. If you’re dealing with large volumes of information, it can also pose significant challenges in terms of processing, storage, and performance optimization. Lots of information takes more time to map and requires more computing resources such as power or memory.
- Data Quality. If your information is of poor quality, has missing values, duplicates, or inaccuracies, it can make it challenging to match fields between the source and the target.
- Complex Transformations. Some tasks in mapping require more complex transformations, including calculations, aggregations, and conditional logic. Implementing these transformations requires attention and careful approach or else the information mapping risks becoming too complex. To make the process easier, you can use a visual tool that allows you see the information mapping in real time or work with a data mapping business analyst.
- Data Governance. When you need to ensure compliance with information governance policies, information mapping can become more complex, especially when it comes to compliance with HIPAA or GDPR. To ensure that everything goes smooth and errorless, manage the information access, security, and consent while mapping data.
- Schema Evolution. Finally, another information mapping challenge is connected to schema evolution. If your project is long-term, you need to track all changes in the structure.
Conclusion
The amount of info generated these days is mind blowing; some businesses generate more information than they can handle, which becomes a huge challenge. When the information overload seems impossible to handle, info mapping comes to the rescue. Without mapping, management and integration wouldn’t be so smooth and effective.
Without info mapping, you don’t have to worry about information inconsistency, inaccuracies, redundancies, and other unwanted issues. In other words, information mapping is the key to your peace of mind.
