In this era of technology, everyone uses emails for mail and messages. Assume you have also used the mailboxes for conversation. Model the object classes that might be used in Email system implementation
to represent a mailbox and an email message.
Assume You are working as a software engineer and now you have been asked to deliver a presentation to
a manager to justify the hiring of a system architect for a new project. Write a list of bullet points setting
out the key points in your presentation in which you explain the importance of software architecture

A class may be a structured diagram that describes the structure of the system.  

It consists of sophistication name, attributes, methods, and responsibilities.  

A mailbox and an email message have certain attributes like, compose, reply, draft, inbox, etc.

Software architecture affects:

Performance, Robustness, Distributability, Maintainability.  

Explanation:

See attachment for the Model object classes which may be utilized in the system implementation to represent a mailbox and an email message.

Advantages:

Large-scale reuse Software architecture is vital because it affects the performance, robustness, distributability, and maintainability of a system.

Individual components implement the functional system requirements, but the dominant influence on the non-functional system characteristics is that the system's architecture.

Three advantages of System architecture:

• Stakeholder communication: The architecture may be a high-level presentation of the system which will be used as attention for discussion by a variety of various stakeholders.

• System analysis: making the system architecture explicit at an early stage within the system development requires some analysis.

• Large-scale reuse:

An architectural model may be a compact, manageable description of how a system is organized and the way the components interoperate.

The system architecture is usually an equivalent for systems with similar requirements then can support large-scale software reuse..

b.. i believe would be the right one sorry if im wrong.

well you could find somebody who doesn't want theirs and ask for it or possibly trick a dealer into giving it to you for free.
