Data quality issues are described in section 2.3 of Block 1. Briefly explain the problems could you face if each of the quality issues are not met in your SIS page.
(note: any relevant examples could be accepted)
Briefly describe the term “Geographic Information System (GIS)”. Also provide two uses of GIS. You will also need to check your e-library or external resources to provide an adequate answer to this question. Zero mark will be awarded for the answers without proper referencing. Harvard

Question 2:
AOU is planning to create a conference management system to keep information about the conferences such as papers presented in the conference, d ate of conference, location etc. The conferences are cond ucted in any of the seven branches. One branch may conduct several conferences. Each conference is id entified by a conference ID. Other d etails to be stored are name, field, year, start date, end d ate and the branch name cond ucting the conference. The branch d etails to be stored are the organizing d epartment, contact person, conference location, email add ress, and telephone number. The contact person could be the branch director or the programme coord inator
A conference would receive lots of paper to be submitted to the conference, but only selected number of these papers will be accepted. Paper d etails are paper ID, title, author name, and number of pages. The paper may have secondary authors. In ad d ition, each paper is given a type (for example S: Survey, B: Brief, F: Full). A paper can be submitted in only one conference and many papers may be submitted to the same conference. Once a paper is submitted in a conference, the system sends a
message to the author acknowledging the paper submission. If a paper is accepted , at least one author should attend the conference to present the paper. The system needs to keep information about the author who presented the paper in the conference. Each author is id entified by a unique author ID, Also has a name, ad d ress, email ad dress, affiliation and contact telephone number of this affiliation. An author can write one or more research papers and a paper have one main author and one or more secondary authors.
The system should also store the number of papers submitted and accepted for each conference along with the paper ID, author ID, conference date, number of attend ees and the conference location for archiving purpose.
Give a conceptual data model (CDM) for this application using the Entity-Relationship model, including the complete E-R diagram, the entity types
and any required constraints and assumptions. Give all degree and
participation conditions details.
