Data Warehousing Vs Data Lakes Flashcards
Start
The first point of contention between data warehouses and data lakes is the structure and organization
Data warehouses excel (?)
In this area because:
- data is cleaned, transformed and organized into a predefined schema before storage
- snowflake and star schema
This careful organization makes it easy (?)
- To run queries
- Create reports efficiently
- business users easily access data they need without wading through irrelevant information
- enabling quick, and informed decision making
The structured nature of data warehouses (?)
makes for data that is
- consistent
- reliable
- ready for analysis at anytime
In stark contrast:
Data lakes store data in its raw, unstructured form.
Where users find themselves spending excessive amounts of time cleaning and preparing the data before analysis can begin.
This inefficiency
Not only hampers productivity
- can result in costly delays in getting critical insights
The chaotic environment of a data lake
- can easily transform it into a DATA SWAMP
- where orgs risk accumulating vast amounts of low quality, irrelevant and poorly secured data.
This lack of organization and ill-managed complexity
- confused
- frustrated users
- ultimately undermining the very purpose of data analysis

So when it comes to data structure and organization
Data warehouses provide a clear advantage. They offer a
- reliable
- efficient
- user-friendly environment
That empowers businesses to harness their data effectively,
driving better decision-making and fostering a culture of data-driven success.
