data engineering

Data engineering tools are software applications or frameworks specifically designed to facilitate the process of managing, processing, and transforming large volumes of data.

These tools provide data engineers with the necessary capabilities to efficiently extract, transform, and load (ETL) data, build data pipelines, and prepare data for analysis and consumption by other applications.

Data engineering tools offer a range of features and functionalities, including data integration, data transformation, data quality management, workflow orchestration, and data visualization.

Top 10 data engineering tools to watch out for in 2023

In summary, data engineering tools play a crucial role in managing, processing, and transforming data effectively and efficiently. They provide the necessary functionalities and features to handle big data challenges, streamline data engineering workflows, and ensure the availability of high-quality, well-prepared data for analysis and decision-making.

Data Science Dojo is offering DBT for FREE on Azure Marketplace packaged with support for various data warehouses and data lakes to be configured from CLI. 

 

What does DBT stands for? 

Traditionally, data engineers had to process extensive data available at multiple data clouds in the same available cloud environments. The next task was to migrate the data and then transform it as per the requirements, but Data migration was a task not easy to do so. DBT short for Data Build Tool, allows the analysts and engineers to manipulate massive amounts of data from various significant cloud warehouses to be processed reliably at a single workstation using modular SQL. 

It is basically the “T” in ELT for data transformation in diverse data warehouses. 

 

ELT vs ETL – Insights of both terms

Now what do these two terms mean? Have a look at the table below: 

	ELT	ETL
1.	Stands for Extraction Load Transform	Stands for Extraction Transform Load
2.	Supports structured, unstructured, semi structured and raw type of data	Requires relational and structured dataset
3.	New technology, so it’s difficult to find experts or to create data pipelines	Old process, used for over 20 years now
4.	Dataset is extracted from sources and warehoused in the destination and then transformed	After extraction, data is brought into the staging area where’s its transformed and then loaded into target system
5.	Quick data loading time because data is integrated at target system once and then transformed	Takes more time as it’s a multistage process involving a staging area for transformation and twice loading operations

 

Use cases for ELT 

Since dbt relates closely to ELT process, let’s discuss its use cases: 

• Associations with huge volumes of information: Meteorological frameworks like weather forecasters gather, examine and utilize a lot of information consistently. Organizations with enormous exchange volumes additionally fall into this classification. The ELT process considers faster exchange of data 

• Associations needing quick accessibility: Stock trades produce and utilize a lot of data continuously, where postponements can be destructive. 

 

Challenges for Data Build Tool (DBT)

Data distributed across multiple data centers and the ability to transform those volumes at a single place was a big challenge. 

Then testing and documenting the workflow was another problem. 

Therefore, an engine that could cater to the multiple disjointed data warehouses for data transformation would be suitable for the data engineers. Additionally, testing the complex data pipeline with the same agent would do wonders. 

Working of DBT

Data Build Tool is a partially open-source platform for transforming and modeling data obtained from your data warehouses all in one place. It allows the usage of simple SQL to manipulate data acquired from different sources. Users can document their files and can generate DAG diagrams thereby identifying the lineage of workflow using dbt docs. Automated tests can be run to detect flaws and missing entries in the data models as well. Ultimately, you can deploy the transformed data model to any other warehouse. DBT serves pleasantly in the cutting-edge information stack and is considered cloud agnostic meaning it operates with several significant cloud environments.
