[CS2113-T18-2] FinancialPlanner #17

ryan1604 · 2023-10-05T09:22:04Z

Financial Planner helps individuals manage their finances effectively and achieve their financial goals. The purpose of such an application is to provide users with a range of tools and features to help them better understand their financial situation.

Good use of loggers and assertions.

I think you tried to apply the singleton principle for some classes. It will be covered in one of the lectures, you can also read ahead under week 10's topics. The current implementation can improve a lot, particularly the instance names, and the way they are accessed.

Generally good job in making a comprehensive developer guide.
I really like your visualizer, that enhances the UI/UX.
Diagrams were present to support the understanding of the program

+## Table of contents


Good use of indentation to organize the Table of Contents.
However, since there are 3 types of indentation, could there be a better way of labelling each line? say 1.1.1?
Just a small suggestion.

 ## Acknowledgements


Comprehensive acknowledgement of others.
Properly citing third-party libraries and tools ensures transparency and gives credit to the original creators.
This section showcases the developer's integrity and understanding of open-source norms.

 ## Design & implementation


Perhaps it would be good to have a Architecture Diagram showcasing your overall design and mechanism of FinancialPlanner. This would give the Developer their needed context should they want to further implement other features to integrate into your program

+  * Advantage: Changes are saved after every command.
+  * Disadvantage: Executing command might slow down the program when there is a large amount of data to be saved.
+
+### Visualization Feature 


Kudos for integrating Xchart!
By having the visual aids, it would definitely allow the user to be aware of their expenses at a glance.
Even though FinancialPlanner is CLI, I like the GUI component added to enhance the UI/UX

 ## Design & implementation

 {Describe the design and implementation of the product. Use UML diagrams and short code snippets where applicable.}

+### Storage Component


The relationship between Storage and SaveData/LoadData seems slightly confusing.
Typically, if Storage is a class providing functionalities like saving and loading, it may have methods for those, rather than being connected to abstract classes representing those actions.
Consider redefining these relationships for clarity.

A clearer distinction or some elaboration on what differentiates Cashflow and Budget would be beneficial.

woodenclock · 2023-11-01T03:36:13Z

docs/DeveloperGuide.md

+According to the chart type (Pie/Bar) argument and the Hashmap obtained from the categorizer passed in, 
+the visualizer displays the specified visualization chart by calling the charting library Xchart.
+
+### Class Diagram


Visualizer seems to have methods that return some kind of chart, but the return types are not indicated.
It would be clearer if return types were included.

The relationship between Categorizer and other classes is not immediately evident.
Perhaps some connecting lines or indications of method calls/dependencies would be helpful.

VIsualizer would do the showing of chart itself. Thus it is a void method call to visualizer to print the chart.

Thanks for the feedback on the class diagram!
Will work on that!

+
+### Sequence Diagram 


In the sequence diagram, it would be beneficial to include return arrows, especially for method calls that yield some kind of result.
The method printDisplayChart(type) is invoked on Ui from VisCommand, but from the class diagram, it seems like the method belongs to the Visualizer class. This discrepancy should be resolved for consistency.
Or am I just confusing myself?

Thanks for the feedback! I can see the confusion. printDisplayChart prints a message telling the user that a chart is being displayed. Visualizer has a method for displaying the actual chart. I have renamed the method for UI to make it clearer. I will add the return arrows as well!

Overall great DG! Very detailed description and plenty of diagrams and code snippets to transmit the content in an intuitive way. Maybe could try to make it more coherent by paying attention to how each detail is actually formatted (colors, bullet points etc.). Kudos also for the use of diagrams!

danielpappa · 2023-11-01T04:26:27Z

docs/DeveloperGuide.md

Overall very good DG, very precise and in depth analysis of the code and detailed description.
Maybe could use a single and coherent way of using bullet points (right now the DG contains >>, 1), 1. and Step 1). This could make the DG look as if actually written by a single person.

 ## Design & implementation

 {Describe the design and implementation of the product. Use UML diagrams and short code snippets where applicable.}


Maybe you could add a brief introduction and overview of your Financial Planner, explaining the goal and purpose as well as its rough overall design in form of an arbitrary architecture diagram. This would also allow further developers an immediate insight into your product and align them with your ideas and implementations from the start.

+* Saving the data once upon exit (Currently implemented):
+  * Advantage: Better efficiency and performance of the program.
+  * Disadvantage: If the program crashes or exits incorrectly, data will not be saved.
+* Saving the data after every command:


Perhaps it should be specified whether this way is currently implemented or not (as is done for the other option) to keep the considerations coherent. Right now I assume it is not, but I would still not be sure.

In the text above Command and RawCommand are omitted, whereas it seems like there should be a dependency between the Categorizer and VisCommand. Maybe some more detailed steps could help clarify these doubts.

Maybe you could include return arrows. Also it could perhaps be helpful to make the alt and opt boxes coherent by applying the coloring to all sequence diagrams in the DG (helps create impression that DG was written by a single person).
