ETL (Extract-Transform-Load)

Data is one of the most valuable asset of any organization. To unlock its maximum potential, data from different sources need to be properly integrated for analytics. This is achieved by ETL data integration. The three main steps of ETL is Extract, Transform and Load, but additionally, there are many more many procedures involved with ETL data services.


Data Extraction

Proper extraction of data from the source systems is necessary to collect data for further processing before analytics. The process of data extraction has to consume minimum resources in terms of power, response time or manpower. This extracted data will be made available as soon as possible to get it ready for the next step in the ETL data integration process.


Data Cleaning

Data cleaning is essential to maintain good quality data in the data warehouse. This step involves detecting the data errors, data redundancies, invalid data and data inconsistencies. In times when data from different sources have to be integrated, data cleaning helps to get accurate and consistent data to ensure that the consolidated data is good enough for analysis.


Data Transformation

This step helps in transforming the collected source data into the form that matches the target. It means converting the units and dimensions of data that can be directly used for the analysis. The data from different sources are also aggregated which results in the increased performance during the analytics.


Data Loading

In this step, the cleaned and transformed data will be loaded into the target environment which is generally the databases. The data loading process should involve as much fewer resources as possible and should be properly executed considering the type of the target. Depending on the kind of target database, the data will be loaded either incrementally or at one go.


Management of ETL Process

Designing a strong ETL architecture and managing it efficiently is important to streamline the entire process of data accumulation and processing. One should also have recovery settings designed to have a fallback option when the ETL system fails. The data sources and the entire ETL process should also be audited frequently to identify and rectify the errors.


Data Staging

The data staging area is where the data from one process is made available for the next process to take over. This staging is also used to save the intermediate results of the ETL process which will be useful in case a step fails. The data staging process has to be used only by the ETL and shouldn’t be made available to any other outside processes.

How new technologies are changing this flow

Traditional ETL Process


In the traditional ETL process, the data extracted from the transactional databases is transferred to the staging area. A disadvantage with traditional ETL systems is that if the kind of analysis doesn’t match with the transactional database, then the whole process of transformation (consisting of both cleaning and transferring) has to be repeated again.

Modern ETL Process


With the modern ETL processes, the staging area has been eliminated and the data loading and data transformation happen directly in the analytics database. With the high powered systems used nowadays, the entire ETL process can be completed in a much shorter time making the data available for analysts faster than the traditional ETL systems.
