CSC72001: Student Enrolment Database Assessment 2 Report

This report presents a comprehensive solution to the CSC72001 Assessment 2, focusing on the design, implementation, and testing of a student enrolment database. The assignment required the creation of a relational database in MySQL using PHPMyAdmin, based on a provided scenario and Entity Relationship Diagram (ERD). The report includes an analysis of client business rules, assumptions made, naming conventions, and data types chosen for the database. Part B of the report details the testing of SQL queries designed to retrieve specific information from the database, such as workshop enrolment lists, workshop counts, student transcripts, and student assessment totals. The student demonstrates proficiency in database design, SQL query writing, and the ability to interpret and fulfill client requirements for a student enrolment system, as evidenced by the provided ERD and the results of the executed queries.

Part A: Analysis
1. Client Business Rules
 The database should be able to store the details of the student in the system and
identified by their unique student identification numbers. The details of the course
enrolments and the workshop enrolments are also required to be stored in the system.
 The unit records are also stored in the system with unit entity and the unit code being
the identity of each units, which are being used in the data storage function.
 The details of teachers are also required to be stored in the database and the teachers
are to be identified by their staffID allocated to each of them.
 The database also stores the details of the workshop and identify each of the workshops
with their unique Ids.
 The database should be able to store the unit offering details that would store the
details of the units and the teachers who are offering the units. In addition to this, the
assessments of units are to be done with the students and hence the details of the
assessments are to be stored in the database.
2. Assumptions Made
It has been assumed that workshops and the assessments are two different entities for the
system. The gradation are to be done by the assessor and it has been assumed that the
gradation are not to be dependent on the total marks obtained by the students.
3. Naming Conventions
To keep consistency, the database will use strict naming conventions that will allow easy
implementation and maintenance of the database when completed. The following
conventions apply:
- camelCase: The camel case is used for the development of the names for the
database when two phrases are used for the name the second phrase starts with a
Capital letter.
- Hungarian Notations: In the Hungarian notation the two phrased words are
separated by an underscore.
4. Data Types Chosen
There are two types of data are chosen for the database which would help them in storing
the details of the tables in the database. The two database datatypes that are being used in
the database storage system are int and varchar. Int is used for storing the integer values
and the varchar datatype is used for string values in the database. The int values are
generally used for the primary keys in the database.
