Data Engineering Presented by Abigail Atiwag Data engineering is a field within data science and computer science that focuses on designing building and maintaining systems and infrastructure for collecting storing processing and analyzing large volumes of data Here are some key topics related to data engineering Data Collection Data engineers design and implement systems to collect data from various sources such as databases APIs web scraping IoT devices sensors logs social media platforms and streaming data sources They ensure data quality reliability and consistency during the collection process Data Storage Data engineers design and manage data storage solutions to store large volumes of structured semi structured and unstructured data This includes relational databases SQL databases NoSQL databases document stores key value stores column family stores graph databases data warehouses data lakes distributed file systems HDFS and cloud storage services Amazon S3 Google Cloud Storage Azure Blob Storage Data Processing Data engineers develop data processing pipelines and workflows to clean transform enrich aggregate and prepare raw data for analysis They use tools and frameworks such as Apache Hadoop Apache Spark Apache Flink Apache Kafka Apache Airflow and distributed computing platforms to handle large scale data processing tasks Data Integration Data engineers integrate data from multiple sources and systems to create unified and consistent datasets They perform data integration tasks such as data ingestion data merging data consolidation data synchronization and data federation to ensure data interoperability and accessibility across the organization Data Modeling Data engineers design and implement data models and schemas to structure and organize data for storage and analysis This includes defining entity relationship models dimensional models star schema snowflake schema data cubes data marts and data structures optimized for specific analytical queries and use cases Data Pipelines Data engineers build and manage data pipelines that automate the flow of data from source systems to target systems Data pipelines orchestrate data processing tasks data transformations data loading and data movement across different stages of the data lifecycle They ensure data pipelines are scalable reliable fault tolerant and efficient Big Data Technologies Data engineers work with big data technologies and platforms to handle large scale data processing and analytics This includes distributed computing frameworks Hadoop ecosystem
