“Without a systematic way to start and keep data clean, bad data will happen.” – Donato Diorio
Data has been the crux of all businesses, all industry segments, be it any size, segment, or geography. With technology penetrating all domains, there is unimaginable data getting generated which can yield great results, if handled properly. Not all data is clean or usable or secure. It must be made usable and secure. Duplicate data must be removed, errors must be rectified, private and confidential information must be protected, data must be aligned to make it appropriate for analysis and decision making.
For the best use of data, comes in the processes of ETL and Data Integration. ETL – Extraction, Transformation, and Loading is a trilogy of processes that collects varied source data from heterogeneous databases and transforms them into disparate data warehouses. These processes help in transforming the unstructured data into valuable, structured information. Two popular names in the world of data integration are Pentaho and Talend. Both have been the favorite of many, owing to their salient features.
Before we move on comparing both, let us quickly look at an overview of both.
Pentaho is business intelligence (BI) software that provides data integration, OLAP services, reporting, information dashboards, data mining, and extract, transform, load (ETL) capabilities – Wikipedia

Pentaho Data Integration (PDI), known as Pentaho Kettle, is the constituent of the Pentaho suite and offers ETL abilities. It is utilized for data migration, data cleansing, real-time ETL, and data warehousing. Pentaho ETL offers ease of use, no-code graphical interfaces, speed, performance, easy collaborations, and modern tools – these few things make PDI well-known and widely-used.
