Introduction
This report is to understand the working of enrollment system. It includes the basic UML diagram required for this system. It contains context diagram, data flow diagram of different levels, entity relationship diagram and the physical database design. It is better to understand a system using the diagram before actually implementing it.
Task 1: Context diagram
In the above diagram, Student enrollment system is designed. It represents the complete information system. The data flow is used to connect the various entities to processes. It contains four external entities student enrollment officer, program editor, student and the time tabling officer (Then, P. H). The student retrieves the information about the subjects or courses and selects from the available list. The timetabling officer can create or edit the time table with the classes and timing. Program director has the option to change the subjects and courses pre-requisites. The student enrollment officer can make the changes with the available courses and subjects.
Task 2 Data flow diagram (Level 0)
Data flow diagram
Data flow diagram is used to represent the system of different levels of abstraction. The higher-level data flow diagram is divided into low levels-hacking information and functional elements. The data flow diagram can be divided into multiple levels. This above diagram is for the level-0 data flow diagram. It is a design of the abstracted system. It shows the system as a single process and its relationship with the external entities (Fleming, P. J). The flow of input and output data is shown using arrows. This diagram contains mainly 4 entities. The student has the inflow for selecting subjects and making for payment. System outflows the customised timetable for every student (Ibrahim, R.). Student enrolment officer can input for the subjects or courses. He can ask for the student report from the system. Program director can edit the details of the courses or subjects added by the officer. The level – 0 diagram is to find the main entities of the system and overall operations which can be performed on it.
Task 3 Data flow diagram (Level 1)
Talking about the level-1 diagram, it is more detailed representation of the system. This diagram contains more described entities. It contains more clear view of the system. It includes most of the operations and external actors. This diagram also includes the database which shows there is a database maintained for the system in which the data will be kept. The time table created by timetabling officer will be stored in the database. He can edit or delete it. Timetable relevant with the selection of subjects made by student will be shared with the student (Victoria, D., Estrella, J., Peche, J. P., Chue-Gallardo, J., Vialardi-Sacín, C., Barrientos-Padilla, A., & Ortigosa, Á.). The description about the subjects and courses will also be saved in the database. Student can retrieve the list of available subjects from the database and they will have their description. Student will access to the subjects and courses but only to view them and select. They can’t make changes in their description.
Task 4 Entity Relationship Diagram
Entity relational model is related with the database design of a system. It is a high-level conceptual diagram (Ongy, E. E.). We can use ER modelling to analyse the requirement of data systematically to produce a well-designed database. An entity-relational diagram is used to represent the real-world entities and the relationship established between them. Every entity is related with either one or more entities. Before actually implementing the database for the system, it is better the design an ER diagram.
The student enrolment system will have to store the information about the students, subject/courses, payment and timetable. The database needs to have different entities to store this information in a proper format. I have included seven entities for this system. A table stores information...
