Study Notes
Data Science Hierarchy of Needs
- Reassessing data collection methods is necessary if results are unsatisfactory
- Aggregate/label: classifying information and executing basic analytics
- Learn/optimize: analytics, metrics, and training data are in place
- AI and deep learning: automation and predictive analytics driven by big data
Data Engineering
- The value of data depends on the job of a Data Engineer
- Data engineering: creating interfaces and mechanisms to manage the flow and access of information
- Data engineers: maintain data to ensure it remains accessible and usable for others
Data Engineering Lifecycle
- Generation: turning raw data into a useful end product
- Storage: managing data infrastructure
- Ingestion: extracting, organizing, and integrating data from disparate sources
- Transformation: preparing data for analysis and reporting
- Serving: providing analytics-ready data to data consumers
Data Engineer
- Converts raw data into usable data
- Extracts, organizes, and integrates data from disparate sources
- Prepares data for analysis and reporting by transforming and cleaning it
- Designs and manages data pipelines
- Sets up and manages infrastructure for the ingestion, processing, and storage of data
Data Engineer Skills
- Technical Skills: • Knowledge of operating systems, infrastructure components, and cloud-based services • Experience with databases, data warehouses, and data lakes • Proficiency working with data pipelines
- Functional Skills: • Designing and managing data infrastructure • Setting up and managing data pipelines
- Soft Skills: • Interacting with upstream stakeholders (data architects, software engineers, DevOps engineers) • Interacting with downstream stakeholders (data scientists, data analysts, machine learning engineers)
