Digital forensic is part of forensic science that
implicitly covers crime that is related to computer
technology. computer and network forensics have evolved to
assure proper presentation of computer crime evidentiary
data into court. The main purpose of forensic is to identify
the origin while maintaining the chain of custody in order to
enable the legal process to take its due course. Digital
forensics is essential for the successful prosecution of digital
criminals which involve diverse digital devices such as
computer system devices, network devices, mobile devices
and storage devices. If any computer related incident
happens, fundamental questions to answer are when and
where the incident occurred and, from which device, system
and geographic location did the incident originate. In this
paper a cyber crime, digital evidence investigation requires
a special procedures and techniques in order to be used and
be accepted in court of law. Generally, the goals of these
special processes are to identify the origin of the incident
reported as well as maintaining the chain of custody so that
the legal process can take its option.While digital
investigations have recently become more common, physical
investigations have existed for thousands of years and the
experience from them can be applied to the digital world.
Data warehousing is defined as a process of centralized
data management and retrieval.Data warehousing
represents an ideal vision of maintaining a central
repository of all organizational data. Centralization of
data is needed to maximize user access and analysis.
