Data Warehousing Helps Users Store, Retrieve, and Utilize Information
Data warehousing is a way of storing business data so that
others can retrieve and use it. Another name for data warehousing
is decision support system, because the data retrieved is
pertinent to making business decisions. All large businesses
need some sort of data warehousing, because as the size of
the business increases so does the amount of data. This data
pertains to customers, financial documents, legal documents
and more. Aside from making this information accessible to
the many business employees, data warehousing also keeps the
data organized.
Data warehousing leaves much of the control to the user.
It allows users to input and load data, and allows users to
demand any amount of data retrieval at any time. With data
warehousing, users always know how much data is loaded and
retrieved. Data warehousing also creates a report for the
individual user by turning the data into useful information.
This way user can customize the reports to contain only the
information he needs. Unfortunately, giving access to too
many users may cause the data warehousing system to work slowly.
Each person needs different levels of access and information
causing the reporting requirements to change constantly.
Though everyone in a business may have access to the data
warehousing system, they do not all necessarily have the same
level of access. The system allows administrators to specify
assign certain levels of access to particular users. Those
lower-level employees will have access to less sensitive information.
Higher employees will have access to more sensitive information.
This type of security keeps data from falling into the wrong
hands. Administrators may apply security defense on a per
application basis, which would only restrict access of data
via certain applications in the data warehousing system. Or,
administrators may install security features on the entire
data warehousing system. Whether they do this depends on the
number of users and the number of applications accessing the
data warehousing system among other things.
Data warehousing is a useful tool that many business managers
should incorporate into their decision-making patterns. The
reporting capabilities of data warehousing are useful to decision
makers, because the information reflects the current progress
of the business. The information also acts as a predictive
tool for future events. Managers can use the information from
data warehousing reports to determine the next steps for the
company.
