Draw the DFDs upto 3rd level for Student Admission System

I'd be happy to help you design the Data Flow Diagrams (DFDs) for a Student Admission System up to the 3rd level. However, since providing a detailed DFD would require a visual representation that cannot be conveyed effectively in plain text, I'll describe the process and elements involved at each level. If you're familiar with DFD notation, this should give you a good starting point to create the diagrams yourself using appropriate software.

**Level 0 DFD: Context Diagram**
At the highest level, we create a Context Diagram that represents the system as a single process. It illustrates the interactions between the system and external entities (actors) without diving into the internal details. In the context of a Student Admission System, the main actors might be Students, Admission Staff, and the University Database. The single process in the center represents the entire system.

**Level 1 DFD: Main Processes**
In the Level 1 DFD, you'll decompose the main process from the context diagram into more detailed sub-processes. Each of these sub-processes represents a significant function of the system. In the context of a Student Admission System, some of these sub-processes might include:

1. **Student Registration Process:**
   This process involves capturing student details, creating a student profile, and generating a unique student ID.

2. **Application Processing:**
   This process involves reviewing the submitted applications, checking if they meet admission criteria, and notifying students about the status of their application.

3. **Admission Decision Process:**
   This process involves making admission decisions based on the evaluation of applications. It might involve assigning scores to different aspects like academic performance, extracurricular activities, recommendation letters, etc.

4. **Fee Payment Process:**
   Once students are admitted, this process handles the collection of admission fees. It might include generating invoices, processing payments, and updating the student's financial records.

5. **Enrollment Process:**
   This process manages the enrollment of students in specific courses. It might involve class scheduling, assigning professors, and generating class rosters.

6. **Database Management Process:**
   This process involves maintaining the student database, updating records, and ensuring data integrity.

**Level 2 DFD: Sub-Processes**
In the Level 2 DFDs, you'll break down the sub-processes from Level 1 into more detailed sub-processes or activities. Let's take one of the Level 1 sub-processes, "Application Processing," and break it down further:
