The software may not have been designed and implemented with the proper user interfaces, may not be capable of handling certain user data inputs, may be too slow, or cannot provide the required outputs for the user. Describe the following:Functional issues associated with your identified project and how you convert these problems into software/system objectives revolve around the designer’s ability to identify problems with the functional I/O of the software in place, or issues may be related to performance, architecture, interfaces, hardware, security, communicationsVarious elements you considered in defining your objectives (system security; ease of future modification and expansion; program needs; allowable operational changes; costs; level of effort; time schedules; and reliability, sustainability, and availability)Provide the sections above, and ensure this is added to your Week 1 project along with any instructor recommendations. This project therefore should be a consolidated project from week to week. Ensure the rules of APA format are followed.

Introduction
Design of client /server design will be meant for facilitating and monitoring communication
between a computer server and other users (De´tienne and Bott, 2002). The server design
application is designed to enable one computer or the end system to function as a server thus
controlling, monitoring and providing service to other computers connected on the same
network. The user’s computer is fitted with enough programs which helps in controlling services
in other computers.
Implementation work to be done
•
The first task will involve determining the number of clients to be connected on the same
network.
•
Secondly, we will determine the location which is more accessible to clients.
•
The other process is to determine the criterial of the system operation.
•
The other task will be suggestion of alternatives in case of system failure.
Objectives
•
The first objective is to ensure that the development of the new-system ensures effective
communication and co-ordination with other computer systems connected on the same network.
•
Secondly, the server design will focus on preventing data leakage between parties
communicating on the same network.
•
The other objective will be determining on whether the customers will be added in batch,
online or both.
3
•
If online, it will be vital to determine if the system users will be allowed to add multiple-
customers within a single execution.
•
The other objective of the design will involve determining whether the user interface will
be in the form of screen or window.
Constraints
Design and implementation of the Client Server Design may be impacted by a number
constraint:
•
First, the design data collection will be done for a small application due to inadequate
funds.
•
Secondly, the design will not involve consideration of external factors such as number of
clients to use the system due to time factor.
•
Lastly, the study will not cater for the type of computer in terms of operating system
which the server can be ran in.
Requirements
Generally, there are a number of factors and requirements which must be factored in when
modelling or designing a client/server design.
•
The first requirement is linked with the LAN or WAN network latencies. The server must
be capable of supporting both the LAN and WAN network system. This will help in ensuring the
new applications is widely used by clients (Software Design, 2018).
•
The design or system boundaries for the model must be extend past the conventional
analysis especially for a single server-queuing. This will help in reducing congestion and
confusion in the network.
4
•
The new server must be capable of sending an RPC to the same node which was used by
the client or local personal computer.
•
It should allow all the available RPC’s to invoke other servers. This will help in
addressing issues to do with the software congestion.
Client/Server Diagrams
The following diagrams represents the nature of how the proposed client/server will be
operating.
Diagram 1
Diagram 2
Using the client server, it will be easy to detect all information being shared on the same network
as illustrated above. As indicated on the diagram 1, the server will be providing all clients with
5
instant information regardless of their geographical locations. Here, internet will be used as the
intermediate connection.
Design description needed to describe the implementation for the client
•
The design will be useful as far as business expansion is concerned. This will be achieved
through facilitating communication between servers.
•
Secondly, the clients are supposed to have a single computer which will serve as the
server for the other computers connected on the same network.
•
A common interface will be maintained with the designed server to avoid confusion or
congestion in the system (Lakos, 2011).
