![]() The two concepts can and should be used simultaneously, as they both serve valuable business functions. That said, in cases where IT teams are the main driver behind data warehouses' implementation, there can be issues with agility. Traditional data warehouses are often noted as being ideal for complex queries and offer considerable security and governance. Data warehouse: This data architecture stores structured data using hierarchical tables and dimensions.However, governance and security are often lacking, along with The facilitation of low-cost, long-term storage for eventual use in analytics applications is arguably the key benefit of the data lake, along with flexibility. Data lake: A collection of raw data that can be structured, semi-structured, or unstructured, with a flat architecture.data lakehouseīefore we go any further, it's critical to quickly illustrate the key differences between the two terms from which data lakehouse is derived: The data lakehouse also supports strong schema enforcement and governance, allows for concurrent data reading and writing, uses end-to-end streaming, and is compatible with multiple data types-structured, semi-structured, and unstructured. A data lakehouse combines the structured data management and processing ability of a data warehouse alongside the inexpensive storage capacity of a data lake.įor example, storage and compute resources are separate in the structure of the data lakehouse, allowing for greater scalability, and it typically uses standardized storage formats. ![]()
