Task 1: Software solution

Read the following information and complete the series of activities that follow.

A CLASS ACT

Sam Sophocles, a retired teacher, is keen to earn some extra money by setting up an online

school for secondary students who need extra help with their learning. Classwork will becreated electronically. Classes will be supplemented by one-on-one and small group tutor

audiovisual sessions using Skype.

He will set up a website where:

students can enrol, check their status, see their grades, collect and hand in work, andsend/receive message with teachers;

students can evaluate courses and teachers at the end of each course; teachers can check their class lists, leave work for students, return corrected work, and

enter task grades;

parents can see their childs progress and send/receive messages with teachers; Sam can monitor class enrolments and student performance; Sam can follow evaluations of courses and teachers to decide whether courses or teachers

need to change;

Sam can post promotional material to attract new enrolments.He has signed up five other retired teachers to run the online classes and he has advertised

online and attracted quite a lot of interest from students.

He needs to keep track of enrolments and has asked you to create a database to help him

achieve this. He has provided you with the following data:

a list of the teachers names; a list of subjects to be offered by the school. There are only a few subjects on offer so

far, based on subjects requested by prospective students and their parents. If the

school prospers, more teachers and subjects will be added over time.

For each subject there could be multiple classes run by different teachers.

Student enrolments will be managed by an online database.

First, students must register at the school. They need to enter their name, address, date of

Student can submit subject enrolment request and teacher can accept and assign the class.

Students can enrol in more than one class.

After enrolling, students are emailed a confirmation which spells out the courses in which

they enrolled and an invoice for the cost of the classes.

Teachers can also log in to the database. They have privileges to enter the teacher area of the

database, which students do not. In this area they can see lists of the students in their classes.

Sam Sophocles also wants to be able to produce:

a list of registered students in ascending order;

a list of teachers and their classes; a summary of income from enrolments per class

All lists must be appropriately sorted.

Task 1Software Solution

1. Design (30 marks): 100 minutes (approx.)

Use appropriate design tools to thoroughly represent:

a. The structure of the database (e.g. tables, relationships, records, fields, validation rules).

b. The logic behind calculated fields.

c. Queries, forms

d. Testing

2. Development (40 marks): 200 minutes (approx)

a. Use a relational DBMS to develop a database to satisfy the needs of Mr Sophocles.

b. Carry out the queries and produce the output requested by Mr Sophocles.

What to hand in after development time expires

Printed entity relationship diagram of tables and relationships Printed table definitions showing fields in each table Printouts showing the formulas behind calculated fields Printouts of the data in each table, appropriately sorted Screen shots of form layout showing buttons, controls etc. The lists and totals requested by Sam Sophocles.

All printouts should be labelled so its clear what they represent.

3. Testing (10 marks): 50 minutes

a. Provide evidence that all functional parts of the database, including validation, are working

effectively. Evidence may include:

manual calculations confirming the databases results; screenshots showing the databases behaviour; a testing table listing the items that were tested, how they were tested, the expected

result, the actual result (if different to the expected result) and how unexpected resultswere fixed.
