Data warehouse structured data optimized for analytical processing and reporting. It is designed to store both structured and unstructured data including raw and semistructured data for various analyses. Data Structure It stores structured data with a welldefined schema usually in tabular form. It stores data in its native format including raw semistructured and structured data without a predefined schema. Data Retrieval It involves a welldefined ETL Extract Transform Load process that structures and cleans data before loading it into the warehouse.
It allows retrieving data in its raw form without the need for onthefly conversion. Transformation can be applied when necessary. Performance It is optimized for query performance often using techniques such as Australia Mobile Number List indexing and preaggregation for fast responses to SQL queries. Prioritizes data storage over query performance. Query performance depends on how data is transformed and processed when queried. Schema Evolution Schemes are relatively static and changes can require significant effort and planning. By allowing readthroughschema it provides flexibility in adapting to changes in data without the need for prior schema changes.
Data Type Flexibility It is designed primarily for structured data It may not handle unstructured data well. It is designed to effectively handle structured semistructured and unstructured data. Use It is primarily used for structured data analytics business intelligence and reporting. It is used for a wide variety of analytics including advanced analytics data science machine learning and data discovery. Cost It often involves higher storage and query costs because data is often replicated and indexed for performance. It is generally costeffective for storing large volumes of raw data but costs can increase with data processing and transformations. data quality consistency and accuracy often through strict data governance practices.
