Explore JSON as a popular semi-structured data format used for data exchange between services and storage systems, and recognize root objects, nested objects, and nested arrays.
Describe three data representations—structured, semi-structured, and unstructured—and illustrate with Excel and relational databases, JSON format, and media/text data, highlighting schema evolution and storage implications.
Identify Azure storage options for structured, semi-structured, and unstructured data, including relational databases and Cosmos DB APIs, plus blob storage.
Identify file formats for structured, semi-structured, and unstructured data, including CSV, Excel, JSON, XML, Avro, and Parquet. Understand Parquet’s columnar storage for big data and Avro’s streaming and schema evolution.
Explore types of data workloads, from OLTP transaction systems to data warehouses, and how ETL/ELT, data integration, and analytics tools power dashboards and machine learning workloads.
Analyze OLTP workloads as source systems that capture real-time, structured transactions with fast inserts, updates, and deletes using normalized, multi-table databases in Azure SQL DB, Cosmos DB, PostgreSQL, and MySQL.
Centralize data from OLTP and external systems into a data warehouse for historical analysis. Clean and transform data to support read-optimized reports and dashboards using star or snowflake schemas.
