Episode notes
Data Warehousing History
- The data warehousing paradigm arose in the 80s to address the lack of real-time business intelligence.
- It involved extracting data from operational systems, transforming it, and loading it into a central warehouse.
Rise and Fall of Data Lakes
- Data lakes emerged about 10 years ago to handle diverse data types and the increasing demand for machine learning.
- However, simply dumping data into a data lake without structure proved difficult to manage and analyze effectively.
Current Architectural Mess
- The current data architecture, with separate data lakes and warehouses, is less efficient than the 80s model.
- This two-pronged approach leads to data redundancy, staleness, and synchronization issues.
