Database design (25%)You are required to provide a graphical representation of the database design process. The following stages are required:

1. Identification of Entities.

2. Entities and Relationships

3. Classification of Relationships (ER Schema)

4. Normalisation – Each relationship must be normalised and all the steps shown.

5. Final ER Diagram with normalised entities; all primary and foreign keys identified.

(The design can be hand drawn, scanned and added here; or it can be completely digital)

Database Implementation (20%):Please implement the database using ArcGIS Personal Geodatabase. Implement all entities, with added attributes (foreign keys), if any. Also create the relationship classes to implement the relationships defined in the ER Diagram.

Submit the completed geodatabase as a .zip compressed file, in addition to completeddocument.

Queries: (55%)

(All queries, question, or sub question must be accompanied by a mapdisplaying the results)

1. Perform queries to figure out how many applicants are from the following regions:

8. Which campus is surrounded by LADs with most highly qualified persons?

Greenwich and Avery Hill campus are located in the same LAD and therefore surrounded by the same LADs, in which reside 455858 highly qualified persons , while only 167307 reside in or around Medway LAD. However, considering a buffer area of 20Km from each campus, Greenwich campus seems to be surrounded by more highly qualified persons.

9. Describe the demographic differences between the LADs surrounding Medway Campus and Greenwich Campus. Discuss your answer using Census and Deprivation Indices.

The first difference identifiable is the fact that, as displayed in the table and map of Query 6, in one of the LADs (Tower Hamlet) around Greenwich campus the dominant ethnic group is not White/British as for the other LADs, but Asian/Bangladeshi. There isalso a relevant number of other ethnic groups diverse from white/British in Greenwich area. Overall for both areas the dominant Ethnic group is White/British (F1664), however in Greenwich area reside a significant mix of cultures.

Furthermore, people who live around Greenwich campus seem to have higher qualifications compared with those who live around Medway campus, in which for most of the LADs the majority of people do not have any qualification. It is true for Medway, Gravesham, Thurrok, Tonbridge and Mailing, Swale and Castle Point.

There are also significant differences regarding the occupation status between the LADs surrounding Medway and Greenwich campus. For example, while none of the LADs around Greenwich campus has Skilled Trades Occupations as dominant occupation, it is the most popular occupation for Medway and Swale LADs which surround Medway campus. For the other LADs surrounding Medway campus the dominant occupations are professional, elementary, and administrative and secretarialoccupations. Considering the LADs surrounding Greenwich campus instead, the dominant occupations are professional, elementary, and administrative and secretarialoccupations.
