How Data Engineering came in to the game and its history

Data engineering is a relatively new field that has emerged in recent years as a result of the increasing amount of data being generated and collected. The term "data engineering" was first coined in the late 1990s to describe the practice of building and maintaining the infrastructure and systems needed to store, process, and analyze large amounts of data.

The field of data engineering has its roots in traditional software engineering, database design, and systems administration. As data storage and processing technologies have evolved, the field has grown to encompass new technologies such as distributed systems and big data processing.

The emergence of big data and the need to process large amounts of data quickly and efficiently has led to the development of new tools and technologies such as Hadoop, Spark, and NoSQL databases. These technologies have enabled data engineers to build and maintain large-scale data processing systems that can handle the volume, velocity, and variety of big data.

In recent years, the field of data engineering has become increasingly important as more and more organizations are looking to leverage data to make better decisions and improve their operations. The rise of data science and machine learning has also driven the need for more sophisticated data engineering techniques and technologies.

Overall, data engineering has come a long way since its inception and continues to evolve as new technologies and trends emerge. The field is now considered a critical component of data science and plays a crucial role in enabling organizations to extract valuable insights from their data.

ACID? 🤔

In the world of data engineering and warehousing projects, the concept of ACID transactions is crucial to ensure data consistency and reliability. ACID transactions refer to a set of properties that guarantee database transactions are processed reliably and consistently. ACID stands for Atomicity , Consistency , Isolation , and Durability . Atomicity : This property ensures that a transaction is treated as a single, indivisible unit of work. Either the entire transaction completes successfully, or none of it does. If any part of the transaction fails, the entire transaction is rolled back, and the database is returned to its state before the transaction began. Consistency : This property ensures that the transaction leaves the database in a valid state. The database must enforce any constraints or rules set by the schema. For example, if a transaction tries to insert a record with a duplicate primary key, the database will reject the transaction and roll back any changes that have alre...

dbt (Data Build Tool) Overview: What is dbt?

If you're working with data, you've probably heard of the ETL process: Extract, Transform, Load. The ETL process is fundamental to data warehousing and analytics, but it can be challenging to implement and maintain. That's where dbt comes in. dbt, or Data Build Tool, is an open-source command-line tool that enables data analysts and engineers to transform, test, and document data using SQL. dbt was developed by Fishtown Analytics and has quickly become a popular tool in the data community. What is dbt used for? dbt is primarily used for building data pipelines and analytics systems. It allows data analysts and engineers to transform raw data into usable formats, test the transformed data to ensure accuracy, and document the entire process for future reference. One of the key benefits of dbt is that it uses SQL as its primary language. This makes it easy for data analysts and engineers to use the tool without having to learn a new programming language or framework. dbt can b...

The Medallion Architecture

Data warehousing is a crucial aspect of modern business intelligence. The Medallion Architecture is a popular approach for designing data warehouses that can effectively meet the needs of an organization. The Medallion Architecture consists of three layers: Bronze, Silver, and Gold. In this blog post, we'll explore each of these layers and their role in building an effective data warehouse. Bronze Layer: The Bronze layer is the first layer of the Medallion Architecture. This layer is responsible for storing raw data. The data is typically loaded into this layer without any transformation or modification. The goal of this layer is to store all the data that an organization collects in its original form, without losing any information. This data can come from various sources, including transactions, logs, and sensors. For example, consider an e-commerce website that collects data on customer transactions. The Bronze layer of the data warehouse for this website would contain all the r...
