How ETL Technology Works: A Step by Step Guide
ETL technology stands for Extract, Transform, and Load. This process is used to migrate data from one system into another such as moving data stored in a database or spreadsheet application to a newly implemented Business Intelligence (BI) software.
In simpler terms, you are extracting data from an existing source and transforming it in the appropriate format before loading it into a new destination with ETL technology. The extraction usually consists of finding specific fields that need to be migrated while the transformation involves reformatting these fields so they can easily integrate within your new destination system. Lastly, this transformed data is loaded into your new BI tool or platform ensuring that all information remains consistent across platforms.
Here’s an overview of how ETL technology works:
This first step involves identifying where the data needs to come from: whether it’s coming from local databases, cloud-based applications like Salesforce/ClickFunnels, Spreadsheets like Microsoft Excel/Google Sheets etc., web scraping techniques or other sources which might contain relevant business intelligence. Once identified we extract this chosen information using dedicated connectors for each datasource type available in our chosen tool.
Once extracted we then transform/massage our raw dataset(s) according to predefined rules defined by us during development & testing against several datasets benchmarks relevant for proper sizing/targeting without loss/inclusion of any significant disparity during original sourcing This includes actions like aggregating multiple columns if necessary; splitting or merging cells/columns; manipulating text values based on regular expressions—lots more depending on what sort/type/level/access point levels exist within extracted raw material gathered utilizing those source connectors already created during extraction phase earlier explained above..
After cleansing and performing transformations at scale & consistency level possible until now having been finished – Info ready! Then We provide secure access as well make sure there exists no inter-dependence between processes concerning entities under different workspace hierarchies with other env types deployed; and that data is ultimately loaded into our newly created BI Dashboard or any other type of platform you’ve chosen to use without discrepancies, subjectivity/omissions anywhere.
ETL technology has many benefits for businesses who are growing rapidly or have a need to integrate systems from several sources. Taking the time to understand how this process works can help organizations make more informed decisions when choosing their BI toolset providers and also uncover new insights hidden within existing datasets which could be used in business operations/subsequent strategy development.
In conclusion, ETL technology may sound complicated at first glance but with proper understanding & adherence bit by bit – your company’s everyday operation will start turning like clockwork providing transparency much needed roadmap shaping direction towards achieving greater possibilities!
