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

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

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 ware house
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

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
