Differences Between Data Lakes and Datawarehouse

  • The main reason for writing this article is to
    project the difference between data lakes and
    data warehouses for helping you to know more
    about data management. Most of the data and
    analytics practitioners will understand the term.
    Let us see the main differences
  • Data Lakes Retain All Data
  • While developing the data warehouse there is a
    need to invest a good time to analyze data
    sources and understand the business processes and
    profiling data. You will get a highly structured
    data model, especially for reporting. In this
    process, the major work is to identify the data
    to include and avoid. The main thing over here is
    to make decisions about the type of data to add
    and to reject in the warehouse.

  • Data Lakes Assists All Data Types
  • Normally the data warehouses consist of data
    taken from the transactional systems and are
    composed of quantitative metrics and they are
    defined by the attributes. Sensor data, web
    server logs, social network activity, text, and
    images are avoided and they are termed as
    Non-traditional data sources. 
  • Data Lakes Support All Users
  • Here you can find 80 or lots of users are
    working. They want to obtain reports and check
    their performance metrics or slice in a
    spreadsheet daily. For these users, the data
    warehouse is actually ideal and it is quite
    structured and easy to use and understand and for
    answering these question it is built with some
    object.

  • Data Lakes Adapt Easily to Modification
  • The important drawback of the data warehouse is
    its longer time consumptions for changing them.
    While developing there is a lot of time invested
    and obtain the warehouse' structure correctly. It
    is a familiar fact that a good warehouse will be
    submissive to change but it will take a lot of
    time for the loading process and the work was
    done to make analysis and report easy.
  • Data Lakes Provide Rapid Insights
  • This difference has been got from the other four
    points and the reason is that data lakes contain
    various data and data types as it enables users
    to fetch their results on a rapid way when
    compared to the traditional data warehouse
    approach. Moreover, this early access to data
    arrives at a price. The data warehouse
    development team does the work and will not do
    work for some or other data sources needed for an
    analysis. There are lots of structured views of
    the data in the data lake that actually looks
    like what they have had earlier in the data
    warehouse.
