General Guidelines
1. A Cover page or title page – You should always attach a title page to your assignment. Use previous page as
your cover sheet and make sure all the details are accurately filled.
2. Attach this brief as the first section of your assignment.
3. All the assignments should be prepared using a word processing software.
4. All the assignments should be printed on A4 sized papers. Use single side printing.
5. Allow 1” for top, bottom , right margins and 1.25” for the left margin of each page.
Word Processing Rules
1.
2.
3.
4.
The font size should be 12 point, and should be in the style of Time New Roman.
Use 1.5 line spacing. Left justify all paragraphs.
Ensure that all the headings are consistent in terms of the font size and font style.
Use footer function in the word processor to insert Your Name, Subject, Assignment No, and Page Number
on each page. This is useful if individual sheets become detached for any reason.
5. Use word processing application spell check and grammar check function to help editing your assignment.
Important Points:
1. It is strictly prohibited to use textboxes to add texts in the assignments, except for the compulsory information.
eg: Figures, tables of comparison etc. Adding text boxes in the body except for the before mentioned
compulsory information will result in rejection of your work.
2. Carefully check the hand in date and the instructions given in the assignment. Late submissions will not be
accepted.
3. Ensure that you give yourself enough time to complete the assignment by the due date.
4. Excuses of any nature will not be accepted for failure to hand in the work on time.
5. You must take responsibility for managing your own time effectively.
6. If you are unable to hand in your assignment on time and have valid reasons such as illness, you may apply (in
writing) for an extension.
7. Failure to achieve at least PASS criteria will result in a REFERRAL grade .
8. Non-submission of work without valid reasons will lead to an automatic RE FERRAL. You will then be asked to
complete an alternative assignment.
9. If you use other people’s work or ideas in your assignment, reference them properly using HARVARD
referencing system to avoid plagiarism. You have to provide both in-text citation and a reference list.
10. If you are proven to be guilty of plagiarism or any academic misconduct, your grade could be reduced to A
REFERRAL or at worst you could be expelled from the course.
11. If you are proven to be guilty of plagiarism or any academic misconduct, your grade could be reduced to A
REFERRAL or at worst you could be expelled from the course.

Assignment Brief and Guidance:
Assignment Brief
Scenario.
‘Data Labs’ is a leading software development company in Sri Lanka. They are focusing on helping
businesses to build their businesses through creative and effective solutions. Assume that you work as an
apprentice software developer for Data Labs company. As a part of your role, you have been asked to
develop a software system (command-line interface based) for the following scenario using python
programming language.
Sampath Food City (PVT) Ltd is one of the main supermarket networks in Sri Lanka. Currently, Sampath
Food City has several branches island wide. At present, transactions of each branch are recorded through a
point of sale (pos) system. At the end of each month, recorded data of each point of the sales system are
transferred to a centralized database. Top-level management of the company use the centralized data to do
the monthly sales data analysis of the whole company at the end of the month to find insights to take
managerial decisions for the company. Currently, the company uses a paper-based manual system to do
monthly sales data analysis. Some weaknesses and drawbacks that have occurred in the manual system such
as human errors leading to inaccurate information, time consuming, data redundancy, inconsistency and
difficulty to find insights affect the business performance negatively.
Therefore, the management of Sampath Food City has decided that using a customized software system
for sales data analysis is the solution for eliminating above mentioned weaknesses and drawbacks of the
existing sales data analysis process.
Assume yourself as a software developer of Data Labs (PVT) Ltd and assigned to develop a sales data
analysis system (command-line interface based) using python programming language for scenario given
above.
New system should provide following features:
9

Monthly sales analysis of each branch.

Price analysis of each product

Weekly sales analysis of supermarket network

Product preference analysis

Analysis of the distribution of total sales amount of purchases
Applied Programming and Design Principles
Assignment no 1
Develop a command-line interface-based solution for the above scenario and produce a report covering the
following tasks.
Activity 1

Investigate the characteristics of the object-orientated paradigm, including class relationships (inheritance,
association, composition, aggregation) and evaluate the impact pf SOLID principles (single responsibility
principle, open/closed principle, Liskov’s substitution principle, interface segregation principle and
dependency inversion principle) by taking suitable examples incorporating UML diagrams and coding
samples. Your answer should include suitable examples to evaluate the impact of SOLID principles in Object
oriented Development.

Explain how clean coding techniques can impact on the use of data structures and operations when writing
algorithms by taking suitable examples from the given scenario. Analyse each of the creational, structural
and behavioral design patterns with relevant examples.
Activity 2

Design a large data set processing application, utilising SOLID principles, clean coding techniques, a design
pattern and data structures by providing justifications for selected design pattern and selected data
structures.

Design a suitable testing regime for the application developed with a provision for automated testing,
selected test types and selected automatic testing tools, and provide justifications for the selections. Refine
the design to include multiple design patterns by justifying the reasons for the inclusion of each design
pattern for the given scenario.
Activity 3
Build a large dataset processing application based on the design produced, by using python programming language
and provide evidence for the usage of data structures and file handling techniques. Your answer must include an
assessment of how effective the use of SOLID principles, clean coding techniques and programming patterns on the
application developed. Take suitable examples from the developed application to elaborate your answer.

Activity 4
 Examine the benefits and drawbacks of different methods of automatic testing of applications and software
systems available for automatic testing by taking examples from the developed application. Provide an
action plan to address the identified drawbacks of testing of the developed application.

Implement automatic testing of the developed application by using selected testing tools and provide
evidence for the automatic testing. Discuss how developer-produced and vendor-provided automatic
testing tools differ for applications and software systems by taking suitable examples from the testing of
the developed application.
