Study Notes
Data Engineering
- Data engineering involves creating interfaces and mechanisms to manage the flow and access of information.
- Data engineers are responsible for maintaining data to ensure it remains accessible and usable for others.
- Data engineers establish and manage an organization's data infrastructure, readying it for analysis by data analysts and scientists.
Data Engineering Lifecycle
- The data engineering lifecycle comprises stages that turn raw data ingredients into a useful end product, ready for consumption by analysts, data scientists, ML engineers, and others.
- The stages include:
- Generation
- Storage
- Ingestion
- Transformation
- Serving
Role of a Data Engineer
- A data engineer converts raw data into usable data, providing analytics-ready data to data consumers.
- A data engineer extracts, organizes, and integrates data from disparate sources.
- A data engineer prepares data for analysis and reporting by transforming and cleaning it.
- A data engineer designs and manages data pipelines that encompass the journey of data from source to destination systems.
- A data engineer sets up and manages the infrastructure required for the ingestion, processing, and storage of data.
Stakeholders
Upstream Stakeholders
- Data architects design the blueprint for organizational data management, mapping out processes and overall data architecture and systems.
- Software engineers build the software and systems that run a business, generating internal data that data engineers will consume and process.
- DevOps engineers and site-reliability engineers produce data through operational monitoring.
Downstream Stakeholders
- Data scientists use data analytics and data engineering to make predictions and recommendations using data from the past.
- Data analysts use data scientists' insights and predictions to drive decisions that benefit and grow their business.
- Machine learning engineers develop advanced ML techniques, train models, and design and maintain the infrastructure running ML processes in a scaled production environment.
Data Engineering vs Data Science
- Data engineering sits upstream from data science, providing inputs used by data scientists, who convert these inputs into something useful.
Data Science Hierarchy of Needs
- Collect: Determine what data is needed and what is currently available.
- Move/Store: Secure movement, organization, and storage of the data.
- Explore/Transform: Focus on data exploration and analysis, including anomaly detection and data cleaning.
- Aggregate/Label: Classify information and execute basic analytics.
- Implement/Optimize: Test, learn, and optimize data usage.
- AI and Deep Learning: Delve into experimentation and scale up the use of machine learning models.
