Data Transformation Best Practices: Expert Insights
Data transformation is an essential part of many data-heavy projects. It requires careful planning and execution for successful results. Here, we take a look at the best practices for data transformation from Zanovoy’s experts in the field.
Understand the source data and its structure
Before beginning any transformation process, it’s important first to understand the source data and its structure. Knowing how it was created, along with any quirks or nuances, can save time when performing transformations in later stages.
Plan ahead and ensure accuracy
When preparing to transform data, plan out each step in advance to ensure accuracy throughout the process. This includes setting up checks to make sure all columns are mapped correctly before any data is actually transformed.
Clean up errors as you go
Always be prepared to clean up errors that occur during the transformation process as they arise. Things like incorrect column mapping or incorrectly formatted input data can cause major issues down the line if they aren’t fixed early on.
Document every step
Documentation is key when it comes to working with large datasets, especially when transforming them across multiple systems or platforms. Keeping track of each step taken will help identify where any issues originated from and give you a better overall understanding of what happened during the process.
Test your transformations thoroughly
Testing your transformations thoroughly is one of the most important best practices for successful data transformation projects. This means testing both pre-transformation validation checks as well as post-transformation results against expected outputs to make sure everything has been handled properly throughout the entire process.
Use quality data cleansing tools
Utilising data cleansing tools can help ensure accuracy and consistency in the transformed data by automatically catching outliers, duplicate values, or other discrepancies that could cause issues down the line.
Leverage automation
Automating some of the more tedious parts of the transformation process can help make it faster and more efficient while also reducing human error. Data analysis software has advanced by leaps and bounds in recent years, so consider working with a Data Transformation specialist like Zanovoy, to ensure you are aware of the latest innovations in data analytics.
Think ahead to future projects
When designing a data transformation process, think ahead to any potential future projects that might need access to the same data set. Taking steps such as standardizing formatting or adding descriptive tags can help simplify future projects involving the same dataset.
Validate frequently
As with every project involving newer technology, it’s important to validate changes frequently during the development and testing stages to catch any issues as soon as possible. This includes validating not only the results of each transformation but also each individual steps taken during development.
Invest in professionals who understand your business objectives
Hiring professionals who understand the specific needs and goals of your business can be incredibly helpful when it comes to transforming data successfully in a timely manner. They should have experience in working with large datasets and know how best to optimize them for later use.
