Assignment Activity 1: Specify a new program, given a small problem description, by identifying relevant data abstractions, and specifying the associated behavior of those abstractions.

When thinking about designing a new program, it’s important to identify relevant data abstractions that can be used to solve the problem at hand. By doing so, you can better understand the problem and decompose it into smaller, more manageable pieces. Additionally, data abstractions can make your code more robust and easier to maintain. In general, you should look for data abstractions that are:

• expressive: they should clearly capture the intent of your code
• efficient: they should be easy and efficient to work with
• modular: they should be self-contained and independent from other parts of the program
• reusable: they should be applicable in other contexts beyond the current problem domain.

Once you’ve identified relevant data abstractions, you need to specify the associated behavior. This includes both the functionality that the data abstraction should support as well as how it should be used in the context of the overall program. When specifying behavior, it’s important to be clear, concise, and consistent. Your code should also be easy to read and understand.  Lastly, you should make sure that your code is testable and bug-free.

Assignment Activity 2: Validate the program’s behavior against its specification prior to implementation using test-driven design, through writing unit tests that achieve basic code coverage.

Before implementing a new program, it’s important to validate its behaviour against its specification. This can be done through using test-driven design, through writing unit tests that achieve basic code coverage. By doing this, you can be sure that the program is working as expected and that any errors or unexpected behaviour will be caught and fixed before going into production. This will save you time and money in the long run, and will make your program more reliable.

When writing unit tests, there are a few things to keep in mind. First, you should make sure that your tests are comprehensive and cover all of the functionality of the program. Second, your tests should be easy to understand and follow. Third, your tests should be reproducible and consistent. Lastly, your tests should be able to be run automatically.

Assignment Activity 3:Design software using basic Object-oriented design principles (coupling, cohesion, single responsibility, substitution), robustness, and design patterns where applicable.

When designing software, it’s important to use basic Object-oriented design principles. These include coupling, cohesion, single responsibility, substitution, and robustness. Additionally, you should also use design patterns where applicable. By following these principles, you can create more reliable and maintainable software.

Coupling is the degree to which a class is dependent on another class. A high degree of coupling means that a change in one class may require changes in other classes.

Cohesion is the degree to which a class is focused on a single purpose. A high degree of cohesion means that all of the functionality in a class is related and serves a single purpose.

Single responsibility is the principle that a class should only have one purpose. This means that a class should only be responsible for one thing.

Substitution is the principle that a subclass should be able to replace a superclass. This means that a subclass should be able to do everything that a superclass can do, and more.

Robustness is the principle that a class should be able to handle unexpected input or circumstances. This means that a class should be able to gracefully handle errors and unexpected behaviour.

When applying these principles to software design, it’s important to strike a balance between coupling and cohesion, as well as between single responsibility and robustness. You don’t want your classes to be too tightly coupled, as this will make it difficult to change one class without affecting other classes. However, you also don’t want your classes to be too loosely coupled, as this will make it difficult to reuse code.

Assignment Activity 4: Analyse the structure and behavior of an existing small to medium-sized codebase by making static and dynamic models and identifying design idioms, including design patterns, present in the code.

When you analyze the structure and behavior of a codebase, you’re decompiling it in your head to fundamentally understand how it works. This understanding comes from making static and dynamic models of the codebase. 

The static model is the code itself. By reading through the source, you can get an idea of what the code is doing and how it’s organized. You can also look at its external dependencies (libraries it uses, etc). The static model is important for understanding what the code is supposed to do. 

The dynamic model is how the code actually behaves when it runs. This includes things like studying how data flows through the system and observing system-level behavior. The dynamic model is important for understanding how the code actually works. 

When you analyze a codebase, you’re looking for both design patterns and anti-patterns. Design patterns are recurring solutions to common problems. They’re not always the best solution to a problem, but they’re often a good starting point. Anti-patterns are recurring solutions to common problems that are actually bad ideas. You want to avoid these.

Some common design patterns include:

• Singleton: A class that can only have one instance. This is used to restrict access to resources that are limited in quantity.
• Observer: A class that subscribes to events published by other classes. This is used to create loosely coupled systems.
• Factory: A class that creates instances of other classes. This is used to encapsulate object creation.

Assignment Activity 5: Evolve a small to medium sized codebase by changing or augmenting behavior of the code through alteration, subtyping or composition.

There are a few different ways you can change or augment the behavior of code through alteration, subtyping or composition. In general, these approaches involve creating a new class that inherits from an existing class, or inserting a new object into an existing collection. By doing this, you can change the behaviour of the original class or object without having to rewrite it from scratch.

One way to change the behavior of code is through alteration. This involves changing the existing code to add new functionality or fix bugs. For example, you might alter a class to add a new method, or modify an existing method to change its behaviour.

Another way to change the behavior of code is through subtyping. This involves creating a new class that inherits from an existing class. The new class will inherit all the methods and variables of the original class, but can also override them to change their behaviour. For example, you might create a new class that inherits from the Observer class, and override the update() method to change how it behaves.

Assignment Activity 6: Recover from common structural issues through identifying those issues, and selecting and applying  the appropriate refactorings.

There are many common structural issues that can plague software development projects. Identifying these issues early on and taking corrective action through refactoring can help prevent significant problems down the road.

Common structural issues include things like poor code organization, loverly complex code, duplicate code, and low modularity. These can lead to problems like code rot, lower maintainability, and increased developer frustration.

There are many different refactorings that can be applied to these issues. Some common refactorings include:

• Extract Method: This refactoring extracts a section of code into a new method. This can help improve code organization and readability.
• Rename Method: This refactoring renames a method to make it more clear what it does. This can help reduce code complexity and confusion.
• Extract Class: This refactoring extracts a section of code into a new class. This can help improve modularity and code reuse.

Assignment Activity 7: Communicate (orally through code demonstration) implementation choices, and the rationale for those choices.

When communicating your implementation choices, it is important to be clear and concise. You should explain why you made the choices you did, and how they will benefit the project as a whole. It is also helpful to provide code examples to illustrate your point.

For example, if you choose to use the Observer pattern, you might say: “I chose to use the Observer pattern because it will allow us to create a loosely coupled system. This will make it easier to add new features and components in the future.” You might then provide an example of how the Observer pattern can be used to add a new feature to the system.

In general, it is best to avoid using technical jargon when communicating your choices to non-technical stakeholders. They are likely not familiar with terms like “pattern” or “refactoring”, and using them will only serve to confusion. Instead, focus on explaining the benefits of your choices in plain language.
