Expert Systems
•Hardware and software that stores knowledge
and makes inferences, similar to a human expert
•Used in many business applications
•They are computer programs that allow user to
benefit from expert knowledge & information
•The system will consists of database & rules
about what to do,how to implement under certain
circumstances
15. Based on Nature of work done
Artificial Intelligence
•Artificial intelligence (AI): the ability of
computers to mimic or duplicate the functions of
the human brain
•Artificial intelligence systems: people,
procedures, hardware, software, data, and
knowledge needed to develop computer systems
and machines that demonstrate the characteristics
of intelligence
16. Based on Nature of work done
Business Intelligence Systems
Business intelligence System is new &emerging
subject in MIS. Proponents of BI state that the
organizations are sitting on a “Gold mine” of
information waiting to be analyzed to yield
tremendous benefits for the organization
The real Gold is the information which indicates
specific patterns in the data which can be used for
deciding new policies or the information which
showing lost opportunities in past,which can be
exploited in future Cont…..
17. Based on Nature of work done
Business Intelligence Systems
BI systems are therefore systems which analyze a
large historical set of data & information stored in
what is called Data mart & data warehouse
BI requires the creation of a data warehouse which is
subject based collection of historical data
Data mining is a process used to digging into the data
& discovering patterns & insights
OLTP tools allow viewing of transaction data on
various dimensions such as for instance, product,
period& sales person
18. Based on Nature of work done
Business Intelligence Systems
The Multi dimensional tools allows
Rolling up or down on any dimension
Viewing reports based on any two dimensions
Taking a subset such as only one product or 1 region
For analysis
These operations are usually known as
Slice(Select a certain subset of Data)
Dice(Turn to any specific dimensions)
Rollup & drilldown operations
