Summary
Data engineering processes involve the design, construction, and maintenance of systems that handle the lifecycle of data, from its collection and storage to its transformation and delivery for analysis and decision-making.
These processes are crucial for ensuring data is accessible, reliable, and usable by other teams within an organization, like data scientists and analysts.
In essence, data engineering processes are the foundation for leveraging data within an organization. By building robust and efficient data systems, data engineers enable other teams to derive valuable insights and make data-driven decisions.

Data Collection
In data engineering, collection refers to the systematic process of gathering data from various sources, often involving the development of systems and pipelines to extract, transform, and load data into a usable format for analysis or storage. This includes both structured and unstructured data from databases, APIs, files, and other origins.

Data Storage
What is Data Storage?
Data storage is the underlying technology that stores data through the various data engineering stages. It bridges diverse and often isolated data sources—each with its own fragmented data sets, structure, and format. Storage merges the disparate sets to offer a cohesive and consistent data view. The goal is to ensure data is reliable, available, and secure.

Data Cleaning
Data cleaning, also known as data cleansing or scrubbing, is the process of identifying, correcting, and removing errors, inconsistencies, and inaccuracies from datasets. In data engineering, this is crucial for ensuring data quality and usability for various downstream tasks like analysis, machine learning, and business intelligence

Data Transformation
Data transformation in data engineering is the process of converting raw data into a more usable format for analysis and other downstream tasks. This involves cleaning, structuring, and enriching data to make it consistent, accurate, and ready for further processing or consumption by data scientists, analysts, and other end-users. It’s a crucial step in building robust data pipelines.

Data Engineering & AI
Data engineering and AI are deeply intertwined. AI relies heavily on data, and data engineering provides the infrastructure and pipelines necessary to make that data accessible, clean, and usable for AI models. In turn, AI is starting to automate and enhance data engineering tasks, creating a symbiotic relationship.
The relationship between data engineering and AI is increasingly symbiotic. Data engineers are the backbone of AI, while AI is becoming a powerful tool for data engineers to enhance their work, improve efficiency, and unlock new possibilities.

Data Delivery
Data engineering delivery is a critical aspect of the data engineering process, focusing on making processed and transformed data readily available and accessible to end-users, applications, and downstream processes. It is the final stage of the data engineering lifecycle, ensuring that the valuable data refined throughout the process is served in a structured and accessible manner to support various needs, such as analysis, reporting, and decision-making.
In simpler terms, data engineering delivery is about providing the cleaned, organized, and transformed data in a format that data consumers (like analysts, data scientists, or applications) can easily use. Think of data engineering as the “refining” process for raw data. Data engineers design and build robust data pipelines that extract, transform, and load data from various sources, preparing it for use. Data delivery is the final step where this refined data is delivered to its intended users.
