What is Data Transformation? Data transformation is a process of converting structured, semi-structured data, and unstructured data from one format or structure to another. This process involves various tasks such as cleaning, sorting, filtering, validating, and merging data from multiple sources. The primary purpose of data transformation is to be compatible with the target system, making it more suitable and organized for analysis or utilization in decision-making processes.
The four types of data transformation are:
Structural Transformation: Involves modifying the data structure and format, such as converting data types, rearranging columns, or reshaping data to optimize the underlying data structure.Content Transformation: Involves modifying the content of the data, such as cleaning, filtering, or aggregating data to remove inconsistencies or improve quality.Value Transformation: Involves transforming the values within the data, such as applying mathematical operations, normalization, or standardization to make the data more meaningful for analysis.Entity Resolution: Involves identifying and resolving duplicates or inconsistencies within the data to ensure data integrity and accuracy.Top 10 Data Transformation Tools Here are the top ten data transformation tools with various features and capabilities that you can utilize to complete the process.
