Assessment Item Briefing Document

Title: CMP2092M Programming Paradigms Assignment

Assessment Weighting: 100%

Learning Outcomes:

On successful completion of this assessment item a student will have demonstrated competence in the following areas:

· [LO1] explain the key concepts in the four main programming paradigms and characterize the nature and compare the applicability of programming paradigms in the context of a given problem scenario. Justify your solution from the architectural perspective of the paradigm you choose.

· [LO2] design a formal definition of a functional problem solution.

· [LO3] Implement the solution in a purely functional programming language

Requirements

Problem Scenario:

A cryptography company has consulted you to implement a simple but crucial text editor system as part of a major contract with a security company to provide fully cloud-based services to a private operator in private equity establishment. Due to security concerns and for a risk of compromising data, your client avoids using the publically available commercial software.

The text editor will be used to record transactions keys of VIP clients from the transactions contained within a multi-platform application controlled from high-end business servers. The passing of data between systems will be handled by a separate team in a sister company so you do not need to concern yourself with the functionality of any other part of the proposed system other than the text editor. The text editor will largely be controlled using trigger commands, but again, you do not need to be concerned with this aspect of the system.

You are to be given ONE opportunity to question a potential user of the system who will provide answers to any questions you might have about the functional requirements of the system. If you are unable to attend the Q&A Session then it is your responsibility to establish suitable mechanisms to ensure you get all of the information you need in order to complete the required tasks.

Your text editor should be able to save and retrieve data from files. Ideally, it should have a user interface – but this is not a core requirement. The text messages that your editor will have to deal with are by definition short and will be constructed wholly as a single line of text and no character formatting will be required.

At this moment in time, your Team Leader does not know which programming paradigm will be used to implement the system and has therefore asked you to provide a short written report detailing the advantages and disadvantages of each of the four main paradigms as solution mechanisms for this particular contract.

You have also been asked to provide an ADT specification for the proposed Text Editor which is presented in the house style and an implementation in Haskell so that your team leader can demonstrate a functional solution to the Department Head. This specification should include formal definitions of all operations that are deemed necessary to fulfill the user requirements.
