ACCURATE REVIEW
●● Databricks Lakehouse Platform
Answer: A platform that empowers everyone on a data science team to
work together, in one secure platform, from the minute data is ingested
into an organization through when it's cleaned up, analyzed, and used to
inform business decisions.
●● Lakehouse
Answer: A storage technology that combines the most popular
functionality from data warehouses and data lakes. An implementation
uses similar data structures and data management features to those in a
data warehouse, directly on the kind of low-cost storage used for data
lakes.
●● Data Warehouses
Answer: A storage technology that generally follow a set of guidelines to
design systems controlling the flow of data used in decision-making.
They are designed to optimize data queries, prevent conflicts between
concurrently running queries, support structured data, and make the
assumption that data entered is unlikely to change with high frequency.
, ●● Data Lakes
Answer: A storage technology that allows an organization to
permanently and cheaply store data of any nature in any format - in fact,
data lakes allow both structured and semi-structured data to be stored
alongside unstructured data like video, images, free text, and log files.
●● Data Swamp
Answer: A poorly maintained data lake that is difficult to navigate and
query.
●● Delta Lake
Answer: An open-source storage layer that brings data reliability to data
lakes through accuracy and completeness to the data. A part of the
combination responsible for laying the foundation for the Lakehouse.
●● ACID Transactions
Answer: A reliability innovation for Delta Lake that guarantees data
validity by performing changes to data as if they are a single operation.
●● Indexing
Answer: A performance innovation for Delta Lake that orders an
unordered table to maximize the efficiency of queries.
