What Should You Know about ETL?

Talking about ETL, it means extract, transform, and load and it is a simple procedure of combining data from manifold sources into a single huge, central repository known as a data warehouse. ETL makes use of a bunch of business rules to clean as well as organize raw data and prepare it for overall storage, data analytics, and even machine learning (ML). You can easily address particular type of business intelligence needs via data analytics (such as predicting the results of business decisions, producing reports and dashboards, lessening operational inefficiency, and even more). You can check out freshworks etl to ensure that you make the most of it.

 A brilliant solution can be supported by ETL or that of even dedicated ETL tool. This post is going to get you a quick walk through ETL and how your business can make the most of it. You know extract, Transform, and even Load are the prime stages you can find in the realm of data integration as well as data migration. With ETL procedure you can easily and effectively form up a data lake, data warehouse, or even a data hub by manufacturing silos of data from numerous sources. This way you can be sure that you form up a correct, reliable, and even streamlined type of data flow. Once you go through the following points in quite detail, you would have a proper understanding of everything.


Talking about data extraction, it is the procedure of fetching data from one or even numerous types of sources. These can be such as data warehouses, analytics tools, marketing and sales apps, cloud environments, CRM systems, as well as manifold other kinds of databases.  


When the transaction takes place, there is proper analysis takes place of extracted data for proper quality. This means that you get to ensure that you find no sort of inconsistencies, even mistakes, missing values, or even duplicate records. If you get to come across any sort of anomalies, the ETL instrument helps you spot them, removes any kind of unusable data, and rejects redundant information or data.

Once you have done these evaluations, deduplication, clearing, and as well as verification processes, the information gets standardized, even sorted, and even absolutely ready for the loading stage. The general step of the transformation absolutely crucial. It is for the reason that it enhances data integrity and also promises that the data you have remains effective, useful, right and most importantly productive.

Proper Loading

Talking about the loading stage, it is something that helps you in importing all the transformed data into the data warehouse or even any other sort of location that acts for your overall business. You can conveniently make sure that you effortlessly load all of it at once and it is called full loading. You can do it either it in batches or that of real-time. you can call it incremental loading.

You know what, the last one might be considered as somewhat better because it would be much easier for you to manage and even does not place massive stress on your overall data warehouse or even that of data lake. Even more, it even prevents data duplication by checking the overall database before making new sets of records of any sort of incoming data. 

Advantages of a good ETL tool 

There are many advantages that your business can reap once it invests in the ETL tool. Of course, once you go through the following advantages, you would be convinced to go for this tool for your business effectivity and growth.

Overall Performance

Firstly, ETL solutions promise you a considerable performance boost to BI users, as much of the overall processing such users would otherwise do server-side happens before the overall database is even enquired for reporting.

Just imagine, for example, that you make a human resource application and are joining data submitted by application users (stored in that of SQL Server) with IRS data on such same employees. A main benefit of ETL tools is that they permit you to join such records, assign new primary keys, overall standardize formatting and naming conventions, filter out immaterial records (or apply tenant columns), and even carry out overall calculations, like the difference between what employees earned this year and even what they earned the last year. Handling all that processing beforehand is going to make reports run significantly faster than that of they otherwise would.

Proper ease of Use

The majority of contemporary ETL applications permit users to interact with it via a GUI (graphical user interface), making it absolutely possible to design ETL processes with moderately little programming knowledge. This enhances the overall number of people upon which a company can actually depend to develop and maintain its overall data warehouse.

The Data Quality

The Transform stage of ETL enables you to apply universal formatting standards as you integrate data sets, paving the overall way for clean and even efficient data models. It’s also a chance to make your data consistent semantically, which is the main ingredient for helping teams with different nomenclature coordinate with one another.

The data can even get made more useful and approachable to stakeholders. How such thing might be done relies heavily on your business context, but just imagine for example that your saas application serves the overall medical community, that makes somewhat frequent use of HCPCS, CPT, and even ICO codes. You could simply join code definition tables with patient record tables to make it absolutely easier for medical personnel to understand and even sort via the codes.

Overall operational resilience

Not just do you not have to depend on your IT team for all data processing, but you can even rest assured that your ETL tool’s built-in error-handling functionality is going to alert you to problems that requires your attention. Solutions built for this purpose leave less area for human mistake, making your processing absolutely efficient and less probable to cause data integrity problems downstream.

Proper ROI

All of the above ETL tool advantages do culminate in higher level of ROI. With growing speed, efficiency, and even data quality comes an ongoing return on your initial investment in an ETL tool as well as data warehousing. Fewer mistakes, fewer personnel, quicker querying, and better results are not going to just help you accomplish more with less but even hone your overall competitive edge.


The point is since you know much about the ETL and how this tool can be great for your business, there is no harm in exploring the overall options.
