Title: ELT Author: Kriko Published: Jun 15, 2023 Last modified: Jul 7, 2026 --- 1. [Home](https://kriko.io/) / 2. [Glossary](https://kriko.io/glossary) / 3. E Letter # ELT ELT is a [data](https://kriko.io/services/data-analysis-insight) integration method used to collect, centralise and analyse large datasets in a structured and scalable manner. The term stands for Extract, Load and Transform. In an ELT process, [data](https://kriko.io/services/data-analysis-insight) is extracted from multiple source systems and loaded directly into a central [data](https://kriko.io/services/data-analysis-insight) warehouse, [data](https://kriko.io/services/data-analysis-insight) lake or cloud- based storage environment. The transformation stage is then performed within the target system. ELT is commonly used in big [data](https://kriko.io/services/data-analysis-insight), cloud analytics and [data](https://kriko.io/services/data-analysis-insight) warehousing projects. Consolidating diverse and complex datasets within a single environment makes them easier to manage, process and analyse. It also allows organisations to scale their analytical workloads more efficiently. By simplifying [data](https://kriko.io/services/data-analysis-insight) integration and taking advantage of the processing power of modern cloud platforms, ELT can reduce the time and resources required to prepare [data](https://kriko.io/services/data-analysis-insight) for analysis. For this reason, it has become a widely adopted approach among organisations that manage large volumes of structured, semi-structured or unstructured data. The ELT process consists of three main stages: **Extract:** [Data](https://kriko.io/services/data-analysis-insight) is retrieved from source systems such as databases, applications, files, APIs and external platforms. **Load:** The extracted [data](https://kriko.io/services/data-analysis-insight) is transferred to a central storage or analytical environment in its original or near-original form. **Transform:** The data is cleaned, standardised, combined and converted within the target system according to analytical and business requirements. Loading data before transformation enables faster ingestion and provides greater flexibility for data analysis. Since the original data remains available in the target environment, organisations can apply different transformation rules to the same dataset without having to extract it again. ELT offers several benefits to businesses, particularly when working with large and complex datasets. Centralising data in a single environment improves accessibility and allows authorised users to retrieve relevant information more quickly. Once the necessary transformations have been completed, data becomes ready for reporting, analysis and decision-making. Faster access to data can also support cost efficiency by reducing the need for multiple tools, duplicated processes and repeated data transfers between different systems. By minimising unnecessary data movement and using the scalable processing capabilities of the target platform, ELT helps organisations access and analyse data more efficiently, quickly and cost-effectively. ## Discover it in the dictionary ### Prescriptive Analytics Prescriptive analytics is an analytical approach that uses predictive modelling, optimisation methods and advanced algorithms to recommend the most appropriate actions.
