The world revolves around big data and lots of big data. Businesses must find an effective way to process all this data to develop effective business strategies. It is at this point that the ELT comes into play.
ELT is the initials of the words “extract, load, and transform.” Indicates a data integration process that extracts, uploads, and transforms data from one or more sources into a repository such as a data warehouse or data lake.
The ELT process consists of three steps:
· Extract: Data is extracted from one or more sources, such as IoT data, social platform data, cloud, or systems within the enterprise.
· Upload: Raw data is loaded into a data lake or data warehouse.
· Transform: The data is converted into actionable business intelligence.
The ELT can be thought of as a newer, more modern variation of the traditional ETL (extract, convert and load) process. Several prominent features are distinguished from ETL.
With traditional ETL, the relevant data must be converted before being loaded into a data warehouse, and then removed from the warehouse for analysis and processing purposes. This data line works, but moving the data from the source to the destination system can take a lot of time.
The cloud-native ELT process saves you stages — and time. The data is first uploaded to the target ecosystem, such as a data lake or data warehouse, and then converted. Authorized users can safely access this data without returning it to the source systems. There is no need to download.
There are reasons to continue using ETL tools. For example, some companies want to keep all their data in-house. If there is a small amount of data, and it is relational and structured, ETL is effective for businesses adopting traditional hand-made data integration. However, the ELT approach has some benefits for many industries.
1. Achieve better results with more efficient effort
The ELT — both structured and unconfigured — allows you to integrate and process large amounts of data from multiple servers. Both raw and cleaned data can be accessed with artificial intelligence (AI) and machine learning (ML) tools, as well as SQL or NoSQL processing.
2. Convert your data faster
ELT does not need to wait for the data to be converted and then loaded. The conversion takes place where the data is located, so you can access your data in seconds — a huge benefit for processing time-sensitive data.
3. Combine data from different sources and formats
Large enterprises typically have multiple, different data sources, such as on-site servers, cloud warehouses, and log files. Using ELT means that you can combine data from different datasets, whether structured or unstructured, relevant or unrelated, without looking at the source.
4. Manage data at scale with ELT
Technological advancements organizations have petabytes (one million gigabytes!) Allows you to collect data. The ELT facilitates the management of large amounts of data by providing access to the storage of raw and cleaned data. If you plan to use state-of-the-art data processing engines such as cloud-based data warehouses or Hadoop, ELT can leverage its unique processing power for greater scalability.
5. Save time and money
The ELT reduces the time it takes to move data and, to transform data outside the cloud, does not require an intermediate data system or additional remote resources. Plus, there's no need to move data in and out of cloud ecosystems for analysis. The more your data moves, the higher the costs. The scalability of ELT makes it cost-effective for businesses of any size.
Transforming data after uploading to modern cloud ecosystems is most effective when:
· Large enterprises with very large volumes of data
· Jobs that collect data from multiple source systems or non-similar formats
· Companies that require quick or frequent access to integrated data
· Data scientists based on business intelligence
· IT departments and data officers interested in low-maintenance solution
The ELT process increases data conversion and processing capabilities thanks to parallel load and data conversion functionality. This scheme allows data to be accessed and queried in almost real time.
However, if you have dirty data, you may not want to leave ETL, just like duplicate, missing, or incorrect data that will require data engineers to clean up and format before data uploads.
If you need to convert large amounts of data, you'll probably need a data management solution that includes ELT. The combination of ETL and ELT is often required for commercial enterprises. A software development company that specializes in AI and cloud-native data integration can help you determine if the ELT process is right for you. You can then create a flow, define business logic, and send processing to cloud data warehouses such as Amazon Web Services (AWS), Microsoft Azure, Google, Salesforce, Databricks, and Snowflake, so that the processing process can occur there locally.
The ELT enables unlimited data management and analysis. Even without an experienced data engineer, you can execute complex integrations at scale. A cloud platform with thousands of pre-installed AI-based functions and templates allows you to easily integrate without code.
You can freely move and access your data across as many cloud ecosystems as you want.
Business intelligence requires skillful data collection, data storage, data transformation, and data analysis. When your company processes data faster using ELT, you can quickly deliver projects and identify and eliminate deficiencies in a very short time.
While speed is important, you should also optimize data governance and security, and remember that you need to keep the end user experience in mind so that access to and use of your company's data is easier.
ELT healthcare works wonders in patient satisfaction, care coordination, and value-based care. Because ELT securely extracts, uploads and transforms both structured and unstructured data, it can quickly compute data from electronic health records (EHR), electronic medical records (EMR), application management software, patient portals, remote patient monitoring, and other data storage systems used by healthcare organizations.
With ELT, Intermountain Healthcare can upload 300 CSV files in 10 minutes — normally a week-long process. There is no need for manual coding because the data conversion process is automatic. Data analysis is the partridge in the bag, as ELT makes data more understandable and highly digestible.
Some government agencies and educational institutions may prefer to keep their data on-premises rather than in the cloud. Although the ELT process is safe, it may not be the most suitable scheme for them. No doubt, public sector organizations can integrate complex data in silos, perform self-analysis, comply with regulations, collaborate across the organization, and modernize operations with ELTs and cloud-based ecosystems.
One of New York City's largest child welfare organizations — The New York Foundling — securely loads and transforms data from Netsmart, Office Practicum, UltiPro, ServiceNow, and Microsoft SQL Server in the cloud and sends it quickly to EHRs. Social workers can access care plans while on the job, so they can spend more time with their clients. They can also easily collaborate with other client care providers.
ELT helps advance production by quickly integrating data from production lines into warehouse systems. It also connects e-commerce data sources and touchpoints such as CRM, PIM, ERP and CPQ systems. Data processing at scale provides quick access to customer and product data — useful for startups looking to increase efficiency and improve customer service. Plus, analysts can process huge amounts of data where they are — and get results in seconds.
Quick access to relevant data allows businesses working in the manufacturing sector to make robust data-driven decisions that will increase production and provide flexibility. For example, ELT helps Rockwool integrate and analyze data from offices and manufacturing facilities in 39 countries. Enhanced data flows increased overall sales by 23 percent. They were able to create automated guided vehicles and warehouse robot technologies for stock collection and replenishment.
The ELT is a reliable way for financial institutions such as banks, capital markets and insurance agencies to operate successfully in agile environments, combat fraud, comply with government regulations, and increase customer satisfaction by providing personalized, secure and contextual interactions with their financial institutions.
Western Union continues to maintain its place in today's financial services market by using ELT as part of its data management system.
