Role as system analyst in Cheltenham Football Club Information System project:
Use of OO approach in designing the system
While designing a system, object oriented approach is selected to capture structure and behavior of the information system which merges data as well as process. OO apprach is used to modify quality as well as productivity of system analysis. OO is iterative stage of system analysis which are taking place throughout software development life cycle. It aims to model functional needs of software while it meets with potential requiremnets of proposed football club system. This approach combines behaviours and stages of analysis processes rather than split into various stages and methods (Dennis, Wixom and Tegarden 2015). The process of OO approach is extenson of system analysis process that preceded with implementation of the project constraints.
UML is recognized platform for designing proposed system. The architeture of system is provided with a framwork on which efficincy of system is based on. This diagram is used to model application struture, and business processes. There is used of UML diagrams in the coursework 1 such as use case diagram, class diagram, sequence, activity and collaboration diagram.
Use case diagram describes system behaviour from point of view of user (Antoniou 2016). The user cases for the diagram are player name provide details of personal team player, login details where the user can enter username, password fom which the system is granted access, registration where the user provides details from an account to create, update use case where the member can enter username, password from which the system can access, game cancel where the member searches for the game to cancel.
Class diagram models the class structure and content with use of design elements like classes and objects. The Cheltenham Football club member management system has player who can create account, check for the details and make payment. The staff can displya actions to do including adding new members, deleting a member from the existing list and generate a report for every three months. The coach can add new game, train the players, cancel the scheduled game and make update for player presence. The game can display that the games are played.
Sequence diagram shows time based dynamics for interacting among objects. There are two sequence diagram for registration and dismissing a player.
Collaboration diagram shows interaction around objects and links to other. The system can validate user that provides assurance to access to other system functionalities. The members can manage, update to queries like member search, player search using search functionalities.
Activity diagram shows flowchart of completing the actions within source states. From the activity diagram, it is reviewed that match details are coming as first option from which the staff member can chack for availiability of game. After validation of game, the players can approved. It is evaluated that the staff member can update details of game and print final report.
Advantage of OO paradigm is improvement over software development efficiency. Objects are reused among the applications based on three factors like modularity, reusability along with extensibility. OO pardigm improves over maintenance of system. Reuse enables quicker developmnet of system. This paradigm comes with rich libraries of the objects and code is developed through the project is reusable (Azar and Vaidyanathan 2015).
Disadvantage of OO paradigm is that OO programs are involved more lines of code than the procedural programs. It is slower as compared to procedural based programs as it is required more commands to perform. OO paradigm is not suitable for all problems as it results in ineffectivee programs (Montgomery 2017). The thought process related to OO paradism is not natural for people. It is critical to create programs based on interacting the objects. The key programming process like inheritance is a challenge to comorehend.
List the key lessons you learned from this project. Clarify what you would do differently if you repeat it and how you can improve the areas, which did not go well. Suggest a suitable Software Development Methodology to use to develop the system you designed? Remember to justify your answers(500 words)
The key lessons learned from the Cheltenham Football Club management system project are:
1.Before start working in a project related to develop of Football club management system, it is required documentation and developed the system with analysis and design.
2.I have learned to evaluate the functional requirements of the system, which is main aspect before commencement of development process.
3.I have drawn the user case documentation with reviewing the possible user cases for the Football Club management system.
4.I have evaluated the user case for staff login, player registration, staff registration, coach registration, modification in member details, searching player, cancelling the game, report generation, payment and view account.
5.I have learned to develop various classes, which can display entire structure of member management system for Cheltenham Football club.
6.I have learned that a sequence diagram is required to predict sequence of each aspect in scenario throughout logical process.
7.I have also evaluated a system activity diagram for understanding processes required to undertake.
8.When a new system is developed, at first I do add logging as well as handling of errors (Oinas-Kukkonen and Harjumaa 2018).
9.By missing the peer review, the system developer losses opportunities to be learned from the mistakes and successes along with experiences of colleagues.
The areas are improved by planning for knowledge experiences, which use technologies for promotion of problem solving, interaction, communication, and higher thinking. The learning opportunities provide the student for collaborating and improving achievement of student. I look for opportunity in order to increase learning over the student.
The software development life cycle (SDLC) is referred to framework, which is used to plan, and control processes for development of information system. The selected SDLC methodology is agile methodology. It is combination of incremental processes to be focused on customer satisfaction by delivery of software products. This model believes that each project is required to handle distinguish and existing methods required to tailor with project requirements (Rechtin 2017). This model is popular among the organization due to flexibility as well as adaptability. Advantages of agile model in this project are:
Apart from the advantages, there are also disadvantages of agile model such as:
Within agile software development life cycle model, self-organization as well as motivation takes precedence over the delegation of the authorities. This particular model is delivering software throughout product incremental cycles over the project documentation (Giachetti 2016). The main objective of this agile methodology is development and delivered the features of product in sustained manner until overall product is to be delivered. The agile methodology is focused on dynamic changes into the product development cycle. The changes are to be carried out while there is development of system features even behind schedule within product development cycle.
