Object-Oriented Modelling and Design

INTRODUCTION

Object-oriented modeling analysis and design is a popular technical concept and approach that analyze or designs the entire application. It is based on the system structure that applies the programming language and also uses visual modeling for software development. Object-oriented modeling analysis follows the top-down approach that is applicable in the graphical representation diagram to analyze the entire system effectively and efficiently. Object-oriented model is the main important phase of development to understand the need and requirement. This modeling system is a type of system that manages the entire database in a proper manner. In this way, it can be classified according to the classes and their relationship among the identified classes. This process will require the effective and efficient life cycle that supports every stage of development. This report will discuss the use case diagram that provides the overall functionality of the user in the database system. Using a case diagram is the best approach based on the graphical representation of the system. It shows the behavior of the diagram and a particular set of actions. This assignment will describe a class diagram based on the different entities and their specified attributes that are applicable in the database management system. All the entities are a specified relationship with one another. Furthermore, it will describe the sequence diagram that represents the interaction between the actors that plays important role in the entire system.

This assignment will design model a single scenario for executing the system in effective manner. There are different participate that has specific roles and it is known as object and entity in the sequence diagram. Sequence diagram is the best approaches that applicable in the development of use case, sequence diagram, and class diagrams. In this report, Data modeling is mainly focused towards the data that process in the structured ways. The basic principle of modeling to encapsulate the data and hiding to develop the system. This process cannot be tampered by other system and their parts. This process will provide the benefits that allows managing the complexity in the software system in effective manner. In this report, It will design the use case and class diagram that representing the relationship between the different entities. This will describe the discussion about the use case diagram and also explain the entire primary Scenario in the form of tables. There are different parameters describe in the each members of use case that specific exceptional cases for identifying the actual need and requirement of business process.

TASK 1

Use case diagram :

Use case diagram is the usually referred as behavior of diagram that describe the actual

Set of actions. It is basically used for the business purpose to perform different action and functions. There are represented the main player which plays main role in the match. There are different information regarding match can be mention in the use case diagram such as Player personal details like name, address, telephone number and email address etc. Afterwards, it also indicates the started time and date of match. The important action can be performed in the match to adjust the times and date of players. In this diagram, it also represented the records and information. On the other hand, the data can be modified, deleted in the user diagram.

This figure representation the specified role of different entities such as player, user and committee. All the objects plays important role in the entire class diagram.

Player:

Player can be manage the own information and details.
It can record of match and shows the availability.
It also records the result and outcome of match.

Committee:

It will create, modify and delete the information of players.
It also requests to reschedule the match and again fix the time as well as date.
Committee is also updated the result of match and finalist the different teams.

User:

User can see the league and match commentary as well as details.

User case diagram is basically the representation of business modeling to create relationship between the players, committee. In this way, they allow managing the entire functionality of tennis match game. A use case diagram is the simplest form of representation of users that interacted with the system. In this way, it can show the relationship between the user and various type of cases involved it. This diagram will identify the types of user in the system which help representation the relationship between them. The main purpose of UML diagram to provide the high level of view requirement. It also provides the complete functional and technical view of system. It can be represented in the form of eclipse and circles.

Class Diagram

Class diagram is generally unified modeling language and it is a type of statistical structure diagram that shows the system of different classes used in the entire system. Class diagram is the mainly building the various block of object oriented modeling. This diagram is usually based on the conceptual part to translating into the coding language.

Syntax of Class Diagram:

For Example-

Class	Player
Attributes	Name Address phone number Email id These are the important attribute of the player class that has some specific
Operations	Player is performed different operations to participate in the leagues and scoring in the different matches. It also stores all the details in the committee.
Visibility	Private
Scope	The scope of player to get information such as get Name, get next new Name etc.

Class	Committee
Attributes	Modify create delete change reschedule
Operations	Committee is the playing important information in the entire match for scheduling the time and date. It also organizes the entire match responsibilities to handle the different task and operations in effective manner. It also modifies, change and delete the match timing and again schedule according to the player's availability.
Visibility	Private
scope	Get schedule, Get next reschedule.

Class	League
Attributes	Results / outcomes Matches
Operations	League is a type of system that consist of different match on the basis of their quality and property. It can be representation of entire results and outcome of match. This will provide the score of each and every match in particular league. This league is divided the different match or specific timing and schedule.
Visibility	Public
Scope	For Example- get match details, get next match new details.

Class	Match
Attributes	Result start date Time Leagues I'd
Operations	Match can provide the final result of the each team. It also performs different operation to fix the start date, time etc. All the timing can be scheduled by the leagues because committee store information and details in the leagues.
Visibility	Public
Scope	For Example- get result, get next new result etc.

Sequence Diagram

Sequence diagram is a based on the interaction diagram that help for design model a single scenario for executing the system in effective manner. There are different participate that has specific roles and it is known as object and entity in the sequence diagram. For Example-0 Player, Match and committee are the participate and there is some communication while interaction can show by using arrows. Payer interact with the match to add the information of each and every player.

Sequence entity

Player

Present Scenario

The player is some specific role in the sequence diagram to add some details and information such as name, address, DOB etc.

Players are also participated in the different match to manage the leagues.

Exceptional case

Player plays important role in the match to perform and participate in proper manner. Players are cannot score the highest due to some reason such as raining and weather changes.

Sequence entity	Match
Primary Scenario	Match can record the each and every details of player and their specific match score. It will mention in the match web system.
Exceptional case	Match can be postponed due to unavailability of pitch and delayed the time. Sometimes, player is score more point. It also categorizes according to their points.

Sequence entity

Committee

Primary Scenario

Each and every member of committee to plan the start and end date of match on the basis of match players.

It also reschedules the match for the presence of all the players. All of them are participated in the match.

Exceptional case

Committee can be change the rules and regulation. They always maintain their procedure of games but in case, it is decided that who is wining team.

Sequence diagram is basically used for representing the different level of participate and also the language for the implementation of case study. This diagram is provide the facility to without coder to read and write the sequence diagram in proper manner.

Sequence diagram of match records

Sequence entity	Record match boundary
Present Scenario	The committee will announce the results according to the score card. It also recorded all the score point on the system.

CONCLUSION

As per discussion, it concluded that use case, sequence case and class diagram are the important for maintaining all the details and informations of entire match system. It summarized the entire details of player, match, committee and league in the match system.
