About Tiny college:
Tiny college is a medium-sized educational institution that performs many
The intensive operations include student registration, academic administrations, inventory management and payroll operations.
Creating an
- In order to create an information system, initial database study needs to be performed to determine the objectives of the information system.
- The operations and processes of the Tiny College are studied in order to identify the opportunities, problems and constraints.
- Problems and constraints identified are being established in the form of precise definition.
- The definition obtained will help designer ensure that the design will improve the efficiency of Tiny College’s in terms of operations.
- Thus improving the operational efficiency will create new opportunity for the Tiny College by providing new services which will improve its position in terms of competitive analysis.
- Initial study to the database is made done, possible alternatives designs are provided to the end user.
- The end user will eventually choose the option that will be more appropriate for the college.
- Developing information system of this size will have different number of peoples involved in the design process.
- Thus there may likely possibilities of large number of peoples involved by providing opinions regarding the proposed
design and system features. - In order to develop an ideal system the designer must merge all the ideas and opinions that are provided to him...

We are going to go over some of the essential characteristics and features of descriptive models in the following paragraphs.
Consider the differences between physical and schematic models and illustrate your points with appropriate illustrations.
A football association is comprised of something like four football crews. Every football crew is made out of eleven to seventeen players, and one player is the commander of the group. The football crews mess around against one another. A group has here and there a chief, and is dependably lead by a mentor. A chief can deal with various groups. Individuals (player, mentor, chief) are distinguished by a name and a location.
