Data transformation is an integral step in many processes employed by organizations today to harness the insights offered by big data, like data integration, warehousing, migration and wrangling. After transformation, data becomes more secure, accessible and usable for a variety of purposes. This process is performed to ensure the compatibility of data with different forms, while blending it with other information or migrating it.
Data transformation facilitates data conversion, irrespective of its form, to be stored, integrated, mined and analyzed for business intelligence.
Data Transformation Definition
The process of converting, cleansing and structuring data in formats that are useful for analysis is called data transformation. It is used when data needs to be altered to match the destination system. The transformed data can be used to augment the decision making processes in an organization, providing actionable insight and propelling growth.
Data transformation typically occurs at two places in the data pipeline. Organizations that store data on-site use an extract, transform, load procedure.
Most organizations today use data warehouses hosted on the cloud, which means they use a type of transformation called extract, load and transform, where the raw data is converted as it is uploaded.
Types of Data Transformation
There are typically four types of data transformation, classified based on their purpose:
Constructive: When data is replicated, copied or added
Destructive: When fields or records in the data are deleted
Structural: When data is reorganized by moving, renaming or combining columns
Aesthetic: When data is standardized to meet particular standards or parameters
Data Transformation Tools: Qlik, Talend and Microsoft
Data transformation tools are designed to manipulate, convert, and prepare data for analysis or storage in a desired format. Some common capabilities of data transformation tools include:
- Data Cleansing: Identifying and correcting errors or inconsistencies in the data such as missing values, duplicates, or outliers.
- Data Integration: Combining data from different sources into a unified format or structure.
- Data Enrichment: Enhancing the existing dataset with additional information from external sources to provide more context or insights.
- Data Aggregation: Summarizing or aggregating data to a higher level of granularity, for example, aggregating daily sales data into monthly or yearly totals.
- Data Normalization: Standardizing data formats, units, or representations to ensure consistency and comparability.
- Data Masking/Anonymization: Protecting sensitive data by replacing identifiable information with anonymized or masked values.
- Data Validation: Verifying the accuracy and integrity of data against predefined rules or criteria.
- Data Transformation: Converting data from one format or structure to another, such as converting raw transactional data into a star schema for use in a data warehouse.

Third-Party Data Transformation
In Qlik Cloud Data Integration, third-party transformation refers to the process of integrating pre-existing data already loaded onto the selected cloud platform using external tools (such as Qlik Replicate and Talend).
This capability enables users to construct workflows atop existing data and integrate it into data pipelines without duplicating processes or double-consuming data. Tasks like creating transformation processes, data cleansing, and automating data warehousing are included.
Examples of scenarios for third-party transformation are:
- Transitional phases during migration from legacy tools to Qlik Cloud Data Integration.
- Utilizing an established cloud data warehouse or data lake for new project requirements.
- Enabling Qlik Cloud Data Integration to interface with proprietary solutions where direct connectivity isn’t feasible.
Third-party transformation aligns with Qlik’s core principles: leaving data in place, registering it, understanding its nuances, enhancing its quality, and commencing delivery processes.
