Data Structures and Algorithms in Java †Free Samples to Students

Question: Discuss about the Data Structures and Algorithms in Java. Answer: Introduction: The report discusses the various data structure types, which are primitive and the non- primitive data structure types. The report also discusses the project schedule an it is stated if the project schedule is justifies or not. Project presented discusses the case of development of a new software. The software is to be designed for the Sydney Group Medical. The motive of the software design is the increase of efficiency in the medical process thus causing a lesser number of death cases. The doctors would be holding an unique doctor ID while the patients would also be having a unique patient ID. While assigning a doctor to the patient a particular doctor ID would be assigned against the particular patient ID. More than one doctor may attend a particular patient. It should be made sure that after the admission of the patient the patient at least one doctor should be assigned. For the storage of the data as to how many patients the doctor is handling the SG Medical wants to design this software. This will help in the efficient management of the data and would also present the other details such as the date, time and the result of the report. The concept of object oriented programming(OOP) can be used in order to do the programming of the project (Smith 2015). The program will be written for the satisfaction of few of the requirements. The first requirement involves that the software should be able to track the record of the patient from any place. The system should not only track the record of the patient but should also be able to arrange appointment for the patient. The software should be platform independent that is should run on any operating system. The program should be developed enough to allow the patient to pick any doctor the patient wants to visit. Primitive data structures are the basic type of data structure. As the machine level instructions are initiated these type of data structures are capable of operating directly (Lafore 2017). Few type of primitive data structure involve integers,floating point numbers,character constants,string constantsandpointers. The Non- primitive data structure is not as same as the primitive data structure on the basis of complexity. The Non- primitive data structure is derived from the primitive form of data structure. The idea is to group all type of data sets, same or different and there is close relationship present among the data items that are grouped. The Arrays, Lists and the Files all are grouped under this category (Joyce and Weems 2016). The project schedule is so designed such that the project is completed within four months. The coding, development and designing process may involve about three hours while the testing process would be requiring one hour (Kerzner and Kerzner 2017). The schedule has been set as per the requirement of the Medical hospital. Below a week wise break up has been provided for the three month designing section of the software. The various tasks around the week will range from the development of the project to the testing an deployment of the software : In this time span of three weeks the team will discuss on how to proceed with the software design. For the answer the requirement of the project has to be known properly. The tools that are required are also identified. This is the most important part as this part will help the team identify its goal. After the identification of the requirements, those are put in the documented format and presented to the client. If the client approves the plan then the team can proceed with the project. After the approval of the client the designing part of the software starts. The team needs to get hold of all the tools that are required during the completion of the project. In this duration the code is written and executed and after the completion of the execution it is deployed in a dummy environment in order to check if the program is carrying out the required tasks. The program would be done with the concept of object oriented programming and a long duration is allotted for the designing purpose as this is the most difficult and complex part. The project schedule is tough to satisfy and achieve with respect to the fact that the task is complex in nature. At the starting of the project the schedule may seem achievable. However, in reality the satisfaction of the schedule is not possible as there may be unexpected errors that may pop in the middle of the project. The project schedule does not look reasonable as errors may even take place at the time of the testing process and all this would again require the checking of the design and would again effect the project schedule and gradually would not meet the overall schedule. The resources should be available in abundance such that there may be sudden requirements of various tools while the project is ongoing. The best way such that the iTech may achieve all the above said criteria in the process of design of the developments of the Sydney Group Medical System software the use of Waterfall model should be made (Rouse 2016). The model can very easily analyze the requirement of the project and the tools that are necessary for the completion of the project. Detailed activities of waterfall model The requirement of the project is analyzed in this part of the analysis. A rough design of the system is made in order to get the idea how to proceed with the project. Implementation: The implementation of the design is made in this step of waterfall model. All the units of the previous stage are united together and after the development of the units each of the units are tested.After completion of all the processes and testing the software is finally deployed. Maintenance: The maintenance of the software is also an equally important part as the issues may continue to arise and it is responsibility of the team to handle these issues as well. Project Management being a complex and lengthy process is not an easy task to be achieved and use of any one specific tool is not sufficient for this purpose (Martinelli and Milosevic 2016). The two most generally used project management tools are: Program Evaluation Review Technique (PERT) Gantt Charts Conclusion: From the report it can be concluded that the software that has to be designed for the SG Medical has to be very structured and efficient as that is responsible for the storage of large number of data. The proper implementation of such type of big and major projects involve the proper planning and setting up the requirements. For this the report puts forward the idea of project scheduling. The report also discusses if the project schedule is reasonable or not as this may arouse future problems for the organization undertaking the project and the organization that is getting the project done. The Water fall model has also been discussed, which is another trusted method for the designing, implementation and the deployment purpose of any project. Other than these the organization should also follow the ethics code of conduct during the implementation of the project. The recommendation is to improve the project schedule and design a project schedule that is flexible and can be adjusted if any issue arises mid way of the project. A well trained, experienced manager is also necessary for proper management of the work and the proper management of the people.
