About the MCS-219 assignment
The MCS-219 assignment covers object-oriented principles, UML diagrams, software modeling and system design. It includes design tasks for a learning management system, an e-commerce order lifecycle and an online shopping system, along with mapping an object model to relational database tables.
There are eight compulsory questions worth 80 marks, with the remaining 20 marks assigned to a compulsory viva voce. Several questions have subparts. The assignment combines conceptual comparisons, architectural analysis and diagram-based work; illustrations and diagrams may be used to support explanations.
What the assignment asks
| Question | Marks | Topic |
|---|---|---|
| Q1 (a) | 4 | Compare object-oriented and structured analysis and design approaches in terms of data-control coupling, computational encapsulation and long-term maintainability. |
| Q1 (b) | 6 | Explain abstraction, encapsulation, inheritance and polymorphism using examples. |
| Q2 (a) | 5 | Compare aggregation and composition through software examples, focusing on their structural meaning and ownership lifecycles. |
| Q2 (b) | 5 | Examine abstract classes and interfaces as design contracts and assess their trade-offs when defining decoupled system boundaries. |
| Q3 | 10 | Create a UML class diagram for a cloud-native learning management system covering user roles, course hierarchies and asynchronous enrollment tracking, with the required notation and domain assumptions. |
| Q4 | 10 | Draw an e-commerce order state machine covering inventory reservation, payment processing, authorization failure, dispatch and refunds, including events, guards, alternative paths and assumptions. |
| Q5 | 10 | Use an ATM example to explain the distinct contributions and interaction of object, dynamic and functional modeling. |
| Q6 (a) | 3 | Explain synchronization features in UML. |
| Q6 (b) | 7 | Describe system-design tasks involving subsystem partitioning, concurrency and process allocation, global resources and data stores, and initialization, termination and recovery. |
| Q7 | 10 | Convert the learning management system class model from Q3 into a 3NF relational schema, explaining inheritance mapping, many-to-many relationships and primary and foreign key constraints. |
| Q8 (a) | 5 | Evaluate difficulties in implementing UML designs in languages such as C++, Java and C#, particularly association mapping and encapsulation. |
| Q8 (b) | 5 | Draw a component diagram for an online shopping system. |

How to write and submit it
- Answer all eight questions.
- Follow the assignment presentation guidelines in the Programme Guide.
- You may use illustrations and diagrams to support your explanations.
- MCA_NEW students must submit to their Study Centre Coordinator by the applicable deadline.
- MCAOL students must submit through the LMS Portal by the applicable deadline.
- Timely assignment submission is compulsory for eligibility to appear in the corresponding term-end examination.
- Attend the compulsory assignment viva voce; submitting the assignment without attending the viva results in zero marks and unsuccessful completion.
Submission dates: 15 April 2027 (June term-end exam; January 2027 session); 31 October 2026 (December term-end exam; July 2026 session).
Frequently asked questions
Which sessions does the MCS-219 assignment cover?
It covers the July 2026 and January 2027 sessions for MCA_NEW/MCAOL.
What are the submission deadlines for MCS-219?
The deadline is 31 October 2026 for the July 2026 session and December term-end exam, and 15 April 2027 for the January 2027 session and June term-end exam.
How are the MCS-219 assignment marks divided?
The assignment has a maximum of 100 marks: 80 for eight compulsory written questions and 20 for viva voce. Its weightage is 30%.
Where should I submit the MCS-219 assignment?
MCA_NEW students submit to their Study Centre Coordinator, while MCAOL students submit through the LMS Portal.
Is the MCS-219 assignment viva compulsory?
Yes. If you submit the assignment but do not attend the viva voce, the assignment is considered unsuccessfully completed and receives zero marks.
Which diagrams are required in this assignment?
The assignment asks for a learning management system class diagram, an e-commerce order state machine diagram and an online shopping system component diagram. It also requires converting the learning management system class model into a relational database schema.
