Solution
Data warehouse :
In computing, a data warehouse (DW or DWH), also known as an enterprise data warehouse
(EDW), is a system used for reporting and data analysis, and is considered a core component of
business intelligence.[DWs are central repositories of integrated data from one or more disparate
sources. They store current and historical data and are used for creating analytical reports for
knowledge workers throughout the enterprise. Examples of reports could range from annual and
quarterly comparisons and trends to detailed daily sales analysis.
The data stored in the warehouse is uploaded from the operational systems (such as marketing or
sales). The data may pass through an operational data store for additional operations before it is
used in the DW for reporting.
Data mining : Data mining is an interdisciplinary subfield of computer science. It is the
computational process of discovering patterns in large data sets involving methods at the
intersection of artificial intelligence, machine learning, statistics, and database systems.
The ways we can use data mining in DHS is :
1) Evaluating use of credit cards by people working in DHS
2)Evaluating patterns of security issues like cybercrime , any illegal transportation issues , mine
details about borde protection people
3)Identifying fraud activities in all departments if any
4)In forecasting of upcoming security issues based on past patterns using data mining
5)In call details analysis , to analyze all the incoming and outgoing calls if they are from people
who cause harm to the country
6)For detecting any malicious intrusions

2. 7)Detect Attacks on critical infrastructurs if any
