2. Introduction

The aim of the combined coursework in this module is for you to select and apply some of the relevant software development and data science techniques that are used in a typical project lifecycle.

Coursework 1 focuses on data preparation and database design.

Coursework 2 continues from coursework 1, focusing on requirements, application design and testing.

This document specifies coursework 1 which is worth 40% of the assessment marks available for the module. This is an individual coursework.

You will submit a written report; and a repository of code files that combined meet the requirements detailed in this specification.

Aim to make progress each week of first five weeks of the module, in line with module’s teaching activities.

3. Coursework specification 3.1. Getting started

1. Select a dataset using the ‘group’ selection task in Moodle Week 1 (https://moodle.ucl.ac.uk/mod/ choicegroup/view.php?id=6089982). Each ‘group’ option is associated with a data set. ‘Group selection’ is a Moodle term for the type of task, the coursework is individual.

2. Accept a GitHub classroom assignment. This creates the repository. Instructions are also given in Tutorial 1.

1. Login to GitHub.com.

2. Click on the GitHub classroom link (https://classroom.github.com/a/zqVIaThf) 3. Accept the assignment.

4. If prompted, accept to join the comp0035-ucl organisation.

                     Page 1 of 10

3. Download the dataset for your group choice and add it to your repository. Use the links in Moodle (Resources > Datasets). For files > 25MB use GitHub large file storage (https://docs.github.com/ en/repositories/working-with-files/managing-large-files/about-git-large-file-storage).

3.2. General requirements and constraints

• Compile all written work into a single report in either PDF or Markdown format. Name the document coursework1.

• The report supports the code and techniques used in the coursework. It is not an essay, be succinct. There are no word limits.

• Demonstrate regular use of source code control using GitHub. Create the repository using the GitHub classroom assignment. Keep the repository private. Keep the repository in the ucl- comp0035 organisation.

• You must use the data set allocated to you on Moodle.

• This is an individual coursework. Do not collude with other students using the same data set.

• Use of code AI tools is permitted when writing code. UCL recommends using Microsoft Copilot

(https://liveuclac.sharepoint.com/sites/Office365/SitePages/Bing-Enterprise-Chat.aspx) using your

UCL credentials. This must be stated in the ‘References’ section.

• Use relevant techniques from the course, or from data science and/or software engineering

processes. Provide references for techniques not included in the course material.

• Diagrams can be hand-drawn and scanned. Using software to draw them does not increase marks.

3.3. Section 1: Data exploration and preparation

The purpose of this section is:

• to use python pandas to describe the data set structure and content; and as a result demonstrate that you understand the data set.

• to use python pandas prepare the data for later use in developing applications. The data you prepare will be used in COMP0034 coursework to create charts in a dashboard app.

• to demonstrate that you can write code that is reusable and understood by other developers.

• to demonstrate that you can apply relevant software engineering and data science techniques.

Code quality is also assessed.

Use only Python and pandas. matplotlib may be used where pandas DataFrame.plot() (https:// pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.plot.html) is not sufficient.

Create charts where they support your exploration and preparation; but do not focus on the visual aesthetic as this is not assessed.

You may need to prepare the data in order to complete the exploration and hence your code may not neatly split between 1.1 and 1.2. This is OK, the code structure does not need to exactly match the report structure.

3.3.1. Section 1.1 Data exploration

1. Code: Write python code to explore and describe the data structure and content. Including, but not limited to, size, attributes and their data types, statistics, distribution of the data, etc. Consider potential data quality issues.

2. Report: Describe the results of your exploration of the data. Do not include the code in the report.

3.3.2. Section 1.2 Data preparation

1. Report: Briefly describe a target audience and state at least 3 questions that they might be interested to explore using the data. This defines the purpose for which you will prepare the data.

         Page 2 of 10

2. Code: Write python code to prepare the data such that it can be used to try to answer the questions for the audience described in step 1. Aim to have sufficient data, and avoid unnecessary data. The prepared data should be in a format that can be read into one or more pandas dataframes from a file (.csv or .xlsx). If relevant, address any data quality issues identified in section 1.1.

3. Report: Explain how you ensured the data is relevant for the purpose.

4. Include the original and prepared versions of your data set files in your repository.

3.4. Section 2: Database design and creation

The purpose of this section is:

• to demonstrate that you understand the structure of a relational database and the principles of normalisation by designing an appropriate database and drawing this as an entity relationship diagram (ERD).

• to demonstrate that you can write Python code to create an SQLite database based on the ERD. The database you create can be used in COMP0034 coursework in a data driven web application.

3.4.1. Section 2.1: Database design

Design a relational database that can store the data (based on either the prepared or the raw data set, your choice). Consider normalisation.

Document the design as an Entity Relationship Diagram (ERD) that includes the following details as a minimum:

• table(s)

• attributes in each table

• data type of each attribute

• primary key attribute for each table • foreign key attribute(s) if relevant

• relationship lines between tables

Include the ERD in your report. An explanation is not required, though you may discuss your normalisation if relevant.

3.4.2. Section 2.2: Database code

Write python code that:

• creates a database structure based on the ERD for an SQLite database file.

• takes the data from the dataset file and saves it to the SQLite database file. Note: do not create a

database that requires a server such as MySQL or PostgresSQL. The quality of the code is assessed.

Use relevant Python packages, i.e. pandas and sqlite3.

3.5. Section 3: Tools

The purpose of this section is to demonstrate appropriate and effective use of relevant software engineering tools.

Page 3 of 10

3.5.1. Section 3.1 Environment management

Provide relevant files and instructions that allow the marker to set up and run your code in a Python virtual environment. They will use pip and setuptools with the commands:

   pip install -r requirements.txt

   pip install -e .

As a minimum, edit the files that were provided in the starter code of the repository:

• requirements.txt: list the packages used in your code

• pyproject.toml: provide basic project details and code package location

• README.md: provide instructions to install and run your code for the data preparation and the

database creation

3.5.2. Section 3.2: Source code control

Add the URL for your repository to the report. Make regular use of source code control.

3.5.3. Section 3.3: Linting

Use a Python linter to demonstrate how your code meets Python style standards such as PEP8, PEP257. For example:

• state which Python linter you used.

• provide evidence of the results of running the linter.

• if issues are reported by the linter, address these and then run the linter again and show the results. • if any issue cannot be addressed, explain why not.

3.6. Section 4: References

Include code references in comments in the code files close to where it is used. Include all other references, if used, in the report.

3.6.1. Section 4.1 Reference use of AI

State either that you used AI, or state that you did not.

If you used AI, include the details stated in the UCL guidance (https://library-guides.ucl.ac.uk/ referencing-plagiarism/acknowledging-AI#s-lg-box-wrapper-19164308).

3.6.2. Section 4.1 Dataset attribution

Comply with any license condition required for your data set (given in the data set link in Moodle > Resources > Data sets).

Each license is different and tells you what has to be cited; e.g. see open government licence v3 (https:// www.nationalarchives.gov.uk/doc/open-government-licence/version/3/). Typically, but not always, ‘attribution’ is required: i.e. include a statement listing who owns the data and its location.

     Page 4 of 10

4. Submission

Refer to Moodle > Assessment for the deadline date and time.

Submit your work on Moodle in the assignment submission. The submission states the upload format:

.zip for the code (and report if in markdown) plus .pdf for the report (if not in markdown).

GitHub is not an acceptable alternative for submission, though its facility to download the code files as

zip may be useful to you.

Make sure all files are in the submission. URLs linking to external files cannot be marked as they could be changed after the submission time. The only exception is where the original data files are too large to upload to Moodle - in this exceptional situation list url(s) to the data files in your report or the README.md instead.

Do not include your .venv folder in the zip file, this creates unnecessarily large zip files. Table: Submission checklist

Commits over a period of weeks could be considered ‘regular’; commits only during a short period such as 1-2 days could not be considered ‘regular’.

6. Appendices

6.1. Code quality

This is considered as:

1. Code that is easy for others to read and understand.

2. Code that is re-usable. The focus in this IEP minor is on writing code that could be used in

applications, not simply on whether the code works.

When you are writing code consider:

• code structure, e.g. use of functions, classes, modules, packages.

• adherence to python conventions (PEP8 style guide (https://peps.python.org/pep-0008/), PEP275

docstring conventions (https://peps.python.org/pep-0257/)).

• documentation (docstrings, comments).

• error handling.

6.2. Code that does not fully function

If your code does not fully work, and you cannot ‘debug’ and fix it before submission, then in the relevant section of the coursework document state as much of the following as you can:

• What is the code that doesn’t work (e.g. a function name)

• What you think the problem may be. This shows you understand the issue even if you cannot solve

it.

• Any solutions you have tried. This shows that you understand the issue and were able to take steps

to try and resolve it.

Clear code documentation (docstrings, comments) is often useful in these situations as the marker can more easily see what you intended your code to do, even if it does not fully achieve that.
