1. A Quick Look At The Data Modeling Tutorial

2. Computer systems are used for the conversion of raw
facts and figures into some meaningful information. The
figures are collected from various sources and then
categorized. These facts act as input for the computer
systems. Information is then outputted after the
processing. This information acts a pivot for decision
making processes. The data modeling tutorial breaks
down the process of data conversion.

3. Different software tools are used for the manipulation of
figures. The software applications used by the
researcher depend on the type of the end result
intended and the type of figures at hand. The definition
of processes is done at the onset immediately after the
categorization stage. The categories also define the
scope of operation within the different levels.

4. Different models are employed in the manipulation of
figures. This depends of the amount of figures at hand
and the type of operation that must be performed. The
basic models are used for manipulating the simple and
straight forward sets of figures. The system requires get
more complicated as the figure sets get complicated.
Most of the assessments are carried out at the logical
level.

5. Raw facts and figures are collected from various points.
In research work, the data forms a very integral part of
research methodology. The facts collected are organized
into different categories depending on the source and
the intended use. The categorization of figures enables
the researcher understand the nature of operations that
are likely to be performed on a particular piece of
information. This also forms a basis of processing.

6. Computer systems have different hardware and
software components. The resources are controlled by
the operating system installed within the system. Some
operations are out of scope of operating system. This
means that the research methodologies being employed
have to be aimed managing the resources available. The
standards for management are set by the operating
platform. Semi-formal models also work in the same
way as the frameworks. In cases where additional tools
are added into the existing system, information integrity
has to be taken care of. This ensures that the
information is not corrupted.

7. There are different levels of modeling. Strategic models
are used for very important operations. The information
that is very integral to the growth and expansion of
organizations at hand is handed at this level. This
operation is carried by employing the best of
methodologies to boost the accuracy. Others types of
models may also be used. This is mainly for the
information that is used to make decisions at middle
level of organizations.

8. The manipulation processes are broken down in number
of ways. Logical diagrams are the most common tools
used for explaining the operations. The framework is
broken down for the end users since the framework is
too conceptual for them. The logical diagrams explain
the stages that the raw figures are taken through for
processing. In some cases, some schematics can be used.

9. A data modeling tutorial may apply the top-down
approach. This happens when explaining a very
complicated concept. Such concepts have to be broken
down in stages. The down-up approach is used when
explaining very simple operations within a computer
system.
