Download file to see previous pages Having viewed these key definitions surround database system, we will apply these principles in the modeling of a database system for our information system. We will model a database that will support a student’s electronic voting system. That will be our business scenario for the study.
The Campus student’s council voting system was initialized as a way of electing the student's representatives. Due to the large numbers of the students, the current manual system calls for a sampling of student’s representatives from every faculty to form an Electoral College. This college would then meet and elect the council members. Thus, the students only participated indirectly in the election process. There is no doubt that this process undermines the whole process of democracy within the student population. This is worsened in cases where aspirants influence the vote of the Electoral College.
In an effort to restore credibility within the election process, we will aim at creating a direct involvement of the whole student population in the election of their leaders. In order to handle the large populations, it, therefore, calls for an electronic voting system. This would not only create transparency but also shorten delays in election conduction period right from voting to polling of results. For an efficient electronic system to exist, it calls for an expertly analyzed database system. It will be the core of this system. For the purpose of this study, we will critically apply the fundamental principles involved in database design and modeling.
A conceptual database design captures how data is modeled. This implies the use of entity relational modeling aspect. This approach will mean deciding the entities that will be part of the system. Linking these entities together and coming up with a suitable schema.
The above entities show a one to one relationship with the Voters_Choice entity. This creates the rule that a student can only have one choice and can select the various candidates once. This confirms the integrity of the whole system ...Download file to see next pagesRead More

Conceptual Design

...Conceptual design (CD) as a process model of design is intuitively appealing because much of design knowledge comes through the experience of multiple, individual design situations. A major task in the development of computer support for design is the identification of the design knowledge to be included in the support tool. Although designers may have difficulty generalizing their heuristics or styles, they usually have no trouble telling stories about previous design situations. If this kind of reasoning can be captured in a computable model of design, the resulting...

Conceptual Design Specification

..., and residential customers in Ontario. The primary functions of the design are the ability of the device to monitor and control energy consumption in an Ontario household and advise the user about the economical use of energy sources namely electricity and gas. Moreover, this wall-mounted device should also be safe, reliable and easy to use for a variety of users including the disabled and multiple ethnic groups. The design team generated five alternative designs which are the remote, the knob controller, the computer-based user interface, the multi-function energy interface monitor, and the energy monitor. The proposed conceptual design is the knob...

Relational Database Design

...Relational Database Design The Design of a Relational Database by This paper describes the process of creating a relational database. Itincludes the SQL code (MySQL) for creating the tables, the joins to create the necessary relationships and the results of those SQL runs. It describes the specifications of the proposed system, the logic of that system, the table definitions and contents, a live transaction which inserts data and one that deletes it and finally a non-trivial query which demonstrates multiple joins, group functions, qualifiers and correlation variables. Relational Database Design The hallmark of the relational database is that when one table changes in the database all other tables are updated and are current. 1... in A Guide...

Logical Database Design the CUSTOMER must have one or more entries in CUST_ACCESS_LOG. While an entry in CUST_ACCESS_LOG must be from one and only one customer. The ER diagram which incorporates all the above assumption/business rules is shown in the below figure: Fig 1: ER model for NHS Health Space In the above diagram, an entry in HEATLTH_RECORD, HEALTH_TARGET, HEALTH_NOTES, MEDICATION, ALLERGIES, CUST_ACCESS_LOG exist only if a corresponding entry exists in CUSTOMER table. Hence these entities are called weak entities and forms total participation with its relationship with CUSTOMER table. Component 2 Physical Database Design 3.
