ELT using Talend
Everything is data-driven in today’s market and loading a data warehouse can be extremely time-consuming. The process of extracting, loading and transforming (ELT) data, streamlines the tasks of modern data warehousing and managing big data so that businesses can focus mainly on data mining and actionable insights. Extract/Load/Transform (ELT) is the process of extracting data from one or multiple sources and loading in into a target data warehouse. The transformation component is pushed to the target database and this helps in improving the performance. This is greatly helpful for processing massive data sets required for business intelligence (BI) and big data analytics. ELT is an alternative and improvised approach to Extract/Transform/Load (ETL). ELT reduces the time data spends in transit and boosts efficiency.
Let us explore what Talend has to offer an as ELT tool.
Talend is an ELT tool used for Data Integration. Software solutions like data preparation, data quality, data integration, application integration, data management and big data are provided by the tool.
