[CS2113T-T12-1] mTracker #32

theodorekwok · 2021-09-30T04:22:39Z

mTracker is a command-line based trading journal interface that allows investors and traders to store and view important trading related information on their shortlisted financial instruments for reference and decision-making. It summarises key details into an easy-to-read format and helps to track profits/losses, thus providing convenient lookups for busy individuals.

Overall, the developer guide provides a wide overview as well as some of the implementation/design rationales behind the components in the application. There was a good use of colours as well to "isolate" the different components for reader to follow.

However, some of the things that I felt could be improved in my opinion would be consistency and maybe reducing/decomposing some of the complex diagrams (which may help in readability).

But again, overall, good job and have a nice day!

+## Design

+> Tip: The diagrams in this guide were designed using PlantUML.
+> Their original .puml files can be found in the diagrams folder here.


I think that this might be due to time constraints but, maybe the "here" could be hyperlinked?

+
+Major components of the app:
+* `MTracker` contains the `main` method responsible for launching and 
+running the app. It first initializes the other components in the correct sequence


The use of "correct sequence" seems to be confusing since there isn't any part telling the read the "correct sequence" to initialize, maybe a general idea of initialization would be sufficient?

+instructions for user input, and other display texts. The class contains both
+  strings of commonly used display texts like the console input prompter, and 
+  methods that print these strings out, thus ensuring satisfactory user interface and 
+  communication with user.


Maybe instead show the user communicating with the UI on the architecture diagram instead? (However I do understand that there might have been some rationale being doing the explanation in terms of word.)

eg.

Sorry for the bad drawing

This is diagram has its good points as it has colours to signify the different components which the system and the colours matches those in the other diagrams.

The only exception of the mismatch of colours would more likely be the ones in the sequence diagrams, though I understand that this could be due to readability reason of the sequence diagram. Perhaps, a different colour scheme could be used for Ui. Or have a note on the sequence diagram - similar to like a legend and explain why the use of another shade colour for the component.

+them during runtime, and restoring data from previous session when the program is relaunched.

+The subsequent sections will elaborate on the more technical design and implementation details of


Really good to have this here, especially to "guide" the reader on what the subsequent parts will be focusing on, in relation to this architecture.

+The figure below represents the class diagram of how all the parser classes interact with classes outside the `console`

+
+<img src="images/ConsoleDiagram.png" width="550"/>


Maybe an additional note or a line of clarification after the digram would be nice to explain why the class diagrams themselves do not contain any methods/variables.

Should the lines between AddXYZParser and AddInstrumentParser, and AddInstrumentParser and InputParser be solid instead of dashed as it is an inheritance association and not an interface implementation association?

+
+### Parser component
+
+The main parent class in `console` package is the `InputParser` class which is defined in `InputParser.java`.


Great to have this here to tell reader what this class/component does and what the following diagram is for.

+Two alternatives to get the instrument information from the user were considered. The first alternative was to
+get the user to add in all the information in a single line with separators
+(for example: `stock TSLA; 909.68; negative; To buy`). This was not implemented as it is likely
+for the user to enter the parameters in the wrong order. This becomes especially problematic if there are multiple


This is good since it tells the reader the rationale being why this previous complex example was not taken into implementation.

+* The command classes are dependent on the `TextUi` class. This allows the command class to display its execution results to the user.
+
+
+The figure below represents the sequence diagram when the user executes a done command:


Maybe could give a more specific use case description, in terms of what this test case does using index? From a reader's point of view, the 1 seems be taken in as an index as of the diagram, but not much seems to be explained about it in terms of the use case, like does this 1 mean just in general any of the instruments that is first in this instrument list, maybe this could be specified here?

Maybe this half of the Command component can be shifted to after the instrument feature? That way, readers would have a rough idea of the implementation behind the instruments which can flow well into the use case of this done Command (Don't mind me too much! Just a suggestion)

+The figure below represents the sequence diagram when the user wants to add a stock:
+
+<img src="images/AddStockSequenceDiagram.png" width="1040"/>


This might be nit-picky, but maybe the the small "hole" between :AddStockParser and the activation bar can be removed? Similarly with the :AddStockCommand

Good use of notes to explain some of the "hidden" logic eg. the prompting of user for more input details.

+in `InstrumentManager.java` and `Instrument.java` respectively. This figure below represents the class diagram of 
+how the different class work together:
+
+<img src="images/ModelDiagram.png" width="550"/>


It may be clearer to include the main class in the diagram to show where the association arrow originates from.

Similar to the console class diagram, should the lines between Instrument and the subinstrument classes be solid instead of dashed.

+The Command component contains all the commands classes, where its respective class is instantiated when a valid command is entered by the user.

+Commands include:


Maybe it will be clearer to display the Commands in a table with a short description of what they do, either here or in an appendix.

Slight typo in AddCryptoCommand

+The figure below represents the sequence diagram when the user executes a done command:

Maybe it will be clearer if the sequence diagram leaves out less important method calls. E.g., getIndex(), getTypeIcon(), getStatusIcon(). As per the instructions here

Agreed! If you would like to go into more details on the parsing process, perhaps consider using a ref frame instead :)

Maybe it will be better to leave out some of the notes as they seem quite redundant. The methods are already well named and seem descriptive enough so there is no need to have the notes. Also, I think can remove the "return" for the return arrow.

Is DoneCommand supposed to be listed here as well? It was mentioned in the sequence diagram below but not here, which was slightly confusing.

While I think it is great that you explained the rationale for your specific choice of implementation, I feel that this segment could have been moved to the "Add instrument feature" segment instead so that this segment is just for showing the overall architecture of the component :)

Perhaps the lifeline for AddStockParser should end after it returns the parameters?
