Uncovering ETL Process To Accelerate Business Growth

25 Mar 2022

You’ve probably come across the phrase – “data is the new oil”. Well, believe it or not it is. With the amount of data generated by organizations day in and day out, it is becoming crucial for businesses to process it the right way since the amount (volume) and variety of raw data are increasing rapidly. And, the world of data management is evolving rapidly with relevant technologies and tools.

Since the last decade, the Extract Transform Load (ETL) process has become fruitful amongst data-driven businesses to ensure smooth business data exchange. It is especially true if the plan to extract and transform information is from several sources before loading it into a centralized repository. If you’re wondering how ETL solutions can help your business boost to a new era of growth, then this article will help you understand the reasons why it is gaining traction across the world.

Here’s What We’ll Cover:

What is ETL Process?

It is the process by which data is extracted from data sources – like existing databases and legacy systems, cloud, hybrid & on-premises environment, mobile devices & apps, CRM systems and moved to a central host. ETL, which primarily means Extract, Transform & Load covers – transportation of data and overlap between each of these stages.

ETL Process Overview

ETL Methodology

Three steps govern the entire process and are applied to diverse data sources to transform raw data into crucial insights.

Extraction

Organizing data comes secondary but what takes the lead is the pulling of data from an array of relevant sources.

  • This is where all the required data is prepared for integration. Interestingly, your data can come from anywhere – whether it means on-premises data, cloud data warehouses, structured and unstructured files, marketing automation platforms and more.
  • Upon consolidation of data, you would notice that all the information is dated & structured in various formats.
  • This is also the stage that prepares the data transformation with a certain level of consistency before it is fed into the system and prepared for conversion. However, it is also important for you to note that the complexity of this step can vary depending on a variety of factors like data volume, disparate data sources & data types.

Transformation

During this phase, the data extracted from diverse sources as accumulated information is converted, reformatted & cleansed before it is ready to be fed into a specific database.

  • The application of a series of functions along with a set of rules ensures the data conversion takes place into various formats that align with the schema requirements.
  • To determine the level of operation required for ETL transformation, you need to have a clear idea about the information that’s being extracted in line with your specific business needs. Do note that this stage also includes validation and rejection of data. Additionally, if the quality of your data is optimal, the transformation would not need to happen on a larger scale.

Here’s a breakdown of the steps involved in this stage:

  • Data conversion as per business needs
  • Reformatting of data to a standard format for compatibility
  • Elimination of irrelevant data from datasets
  • Sorting & filtering of data
  • Elimination of duplicated information
  • Translation where applicable

Loading

Now comes the part where the extracted and transformed datasets are loaded into the specific database. This can be done in two ways.

  • The first one is an SQL routine. It involves the manual insertion of every single record of the target database.
  • The full load process is divided into two types: full loading and incremental loading.
    • Full loading process happens only at the first data loading task to populate the destination – it happens with all the available data.
    • Post that, the incremental loading enables loading the updated data
  • Also, it is important to note that the increments could be;
    • Streaming increments – to handle small volumes of data with regular updates
    • Batch increments – to handle a large volume of data

Importance of ETL in an Organization

There is an array of reasons for an organization to make the most of an ETL process. Here are some of the most significant ones based on our experience :

Better Performance

The ETL infrastructure is such that it helps you adopt new technologies to help you gain a competitive edge. This will also help you simplify the data processes. Additionally, many tools help with improving the performance that comes as an add-on for the ETL process.

Enhanced Business Intelligence

ETL tools enable data access by simplifying the process of extracting, transforming & loading. It helps businesses make faster & well-informed decisions that are based on data-driven facts. The technology is such that it helps you access data with ease. What this means for you is the ease for business leaders to retrieve information based on their specific needs and make decisions accordingly.

Higher & Improved ROI

The management of tons of data is a mammoth task. And not having appropriate tools & processes will only bring in more misery! Think about the unproductive use of resources & the lack of intelligent insights that would worry you all the more. ETL tools & processes help businesses to save costs and thereby, generate higher revenues.

Top ETL Tools

Talend

As the top ETL tool, it can connect with absolutely any data warehouse. Its interactive user interface makes it an attractive option for businesses that want to transform data & create custom workflows.

  • A code generation approach requires you to make every change using logic.
  • Ideal for businesses that have tech-savvy resources or those that have an extended arm of IT professionals. While that is the case, it sure has some features that would wow you, like hybrid & multi-cloud operations that support data governance needs. Further, you can also manage the entire data lifecycle, without letting data quality take a hit!

AWS Glue

Part of the Amazon ecosystem, it works well for organizations that rely on Amazon data warehouses and other services. It can automatically generate scripts in Python and Scala to create efficient ETL processes.

  • Performs an array of activities on your data, which includes data preparation, data ingestion, data transformation, through to building a data catalog.
  • Meeting all the requirements for data ingestion, helps you analyze your data effectively. This data can then be easily utilized instead of waiting for months! Its code-based and visual interfaces make data integration way easier. These features make it easy for users to look for relevant data.

Final Words

Every business in the world today, irrespective of its size is thriving on a vast amount of data. From gaining a 360-degree of customer data to streamline partner onboarding, ETL offers a host of valuable uses. But without a knowledgeable team and powerful tools, this information cannot be cleaned up or made accessible for analysis.

To put it simply, robust ETL tools and processes act as controllers for BI and Data Visualization. This is because they control the flow of data between myriad source systems and applications. Therefore, as data management becomes more complex, the data integration tools also need to change while keeping up the pace.
