You intend to develop an online voting system for general elections. The major use cases of the voting model system include authorizing User that includes simple users and the system's staff. The system manages election districts and election units. The election unit is the system counterpart of the election center. In the conceptual model, the election center is central to the election procedure, as it is the fundamental tallying point. The votes are casted using machines provided by the state and are places at the election center. The fundamental assumption of this system is that almost all citizens above a certain age should be able to participate in the election procedure. It is practically infeasible for election staff to manually enter all electors into the system. The system should thus be able to import an electronic list of electors. This system also manages different political parties and their respective candidates participating in the election procedure. Any authenticated user can Preview Ballots to preview the electronic ballots for any election district. An authenticated user can Cast votes. Thus, all the activities and changes in information/states of the election system at districts and units manage in the central election center database. The system also deals with the final tally calculation. All internal system operations must be logged without sacrificing voter confidentiality. Information regarding any of the above functions should be private, even if transmitted over public networks.

You need to answer the following questions. 

1.Proposed and justify one or more suitable architecture style(s) for the above scenario to improve interaction and sharing of system components.

2.Provide a graphical representation of your architecture style(s) according to the functionality and behavior of the given scenario system. 

3.Define assessment and valuation methods to improve the quality attribute of the proposed architecture style for the given scenario.
