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. Talend is a collection of all the products for the services mentioned above.

How Talend works as a Data Integration tool

An organization’s raw data is extracted from numerous sources and stored in a data warehouse using Talend integration platform. Real time data is being handled by OLTP (Online Transactional Processing) system on any database. The Talend Integration platform replicates the data from OLTP system to data warehouse systems. Thus, Talend helps in integrating data from various systems and move them into data warehouses. All this is done with real-time data and around 1000 integration jobs are executed daily.

Data tools are in plenty in the market and the competition is very fierce. The ELT tools worth mentioning among the lot, apart from Talend, include Hevo Data, Luigi, Blendo, Matillion, StreamSets, Etleap, Airflow, Kafka, Nifi etc.

 

As compared to other ELT tools, Talend stands out with the following features:
