2. Business intelligence (BI) is a broad category of applications and
technologies for gathering, storing, analyzing, and providing access to data
to help enterprise users make better business decisions. BI applications
include the activities of decision support systems, query and reporting,
online analytical processing (OLAP), statistical analysis, forecasting, and
data mining.
Business intelligence applications can be:
•Mission-critical and integral to an enterprise's operations or occasional to
meet a special requirement
•Enterprise-wide or local to one division, department, or project
•Centrally initiated or driven by user demand
3. The crucial position that BI occupies in a company or an organization is dramatically

Answer some questions .
Which goes through sequence of stages :
Extract information load of data ETL which is

stands for Operating Data store which is basically a
datawarehouse which job is to connect the source
system with the destination one , as well as not
allowing the servers to be fully saturated .
5. It is the name given to a type of data base dedicated to serve only one department
In the enterprise , a DATAMART can be fed with data from the Datawarehouse
And can also be used for analysis purposes in solving problems when found .
OLTP (On-line Transaction Processing) is characterized by a large
number of short on-line transactions (INSERT, UPDATE, DELETE). The
main emphasis for OLTP systems is put on very fast query processing,
maintaining data integrity in multi-access environments and an
effectiveness measured by number of transactions per second. In OLTP
database there is detailed and current data, and schema used to store
transactional databases is the entity model (usually 3NF).
6. OLAP (On-line Analytical Processing) is characterized by relatively low volume
of transactions. Queries are often very complex and involve aggregations. For OLAP
systems a response time is an effectiveness measure. OLAP applications are widely
used by Data Mining techniques. In OLAP database there is aggregated, historical
data, stored in multi-dimensional schemas (usually star schema).
7. Dashboards often provide at-a-glance views of KPIs relevant to a particular
objective or business process (e.g. sales, marketing, human resources, or
production).[2] The term dashboard originates from the automobile dashboard
where drivers monitor the major functions at a glance. Dashboards give signs
about a business letting you know something is wrong or something is right.
