What is Data Warehousing?
Data warehousing is a term used to describe the collection and storage
of historical data for analytical purposes. The data can be stored
on a server or in the cloud. This was introduced in 1988 by IBM
researchers Barry Devlin and Paul Murphy. The data collected is analysed and
insight is given on historical data and where your business can
improve. Data warehousing is different to a data base in the fact
that a database will only store the most recent/relevant information and this
information can be changed regularly whereas the data in a data warehouse
remains unchanged, new data is simply added instead of replacing existing
data. A data warehouse will collect all the information, and
everything will be stored for analysing. Patterns are identified, and
improvements can be made. The data to be warehoused can be retrieved
from more than one resource.
How it's done?
To create a data warehouse, data needs to be extracted from your
operational systems. The data is then cleaned. This
process includes the correction of any possible mistakes ensuring all data is
usable and accurate. The data collected from the database needs to
be converted from the current format to the format used in the data
warehouse. It can then be uploaded to the data warehouse for future
use. In the data warehouse, different tables and formats may be used
to make the data more user friendly. Various reporting tools and
applications can be used to retrieve the data from the data warehouse such as
Power BI, Click View and others. There’s no need to change your
current reporting tools.
What are the benefits?
- A data warehouse can be used
to share non-confidential information with other employees and
departments.
- Data from different sources
can be combined into one safe and secure place for comparison and
analysis.
- Data can be stored even when
the source location’s data is changed on a regular basis.
- Information can be displayed
consistently, and the data can be restructured to provide thorough details
for analysing and identifying patterns in your business processes.
- Quickly and effectively
identify market changes and respond to opportunities.
