If the student is object oriented based database model then what kind of properties and classes of the student object.

How to implement the student object in the object oriented database management system model classes and their attribute?

The student object and its class

• In the student object there are some fields and classes are given in the class of the ‘Student’.
• The Name of the student is a character property of the student object data.
• The class is field that represents the ‘class in school for student’ which is connected to the strong line.
• The roll number of the student is unique property in the class room in school.
• The address of the student data is composed data for future use to find student record and holds the address record of the student.
• The Time table of the student is the attribute domain which is connected to the dash line (----) time table attribute.
• Fees of the school are money to submit the school which is defined for their criteria of the student classes.
• Admission number is a unique identity number which is recorded in the admission register database.
• Transfer certificate of the student is another class of the student if the student is not eligible for school of terms and conditions that student follows in the school.
• School performance of the student is a property that of the in the school that student will prove the student performance is good other than weak student in their study and health condition.
• Curriculum activity is hobby of the student where the student can take an interest such as music, art, roll acting etc.

Can a Student object have multiple addresses?

It may be yes or no because it depends on the address types for students' requirements related options developed in the object oriented database model to store address data that students follow with their own requirement.

In many cases the students might have multiple addresses such as:

- A permanent address (e.g., home address)

A permanent address can be defined by the government department that verifies the house of parents of students living at specific locations.

A permanent address is a residential address for the students that their parents mentioned officially for the school to give a proof of the house with postal address related.

- A local address (e.g., dorm or apartment)

Local address is a temporary address that can be changed anytime depending on the students and their regular reach at the geographical location on the maps.

- An emergency contact address

It is an address that is used when the school tries to contact the students with special cases such as: students Missing, students injured, students bad behaviour etc. to their parents to improve their personality and changes into good behaviour and other improvements.

Having multiple addresses can be useful for various purposes, such as:

- Sending mail or packages

Sending mail or packages that means the sending mail can be sent where the parents and guardians are living currently at their specific geographic location based on postal address.

- Contacting the student

Some students are living at paying guests as a student to study for specific coaching or centers that learn their skills to improve also which is only a temporary address of the students to contact.

- Verifying student information

Verification of student information means when the institute sends a letter to the home address of the students they verify their living address for their specific verification to get also the police verified address or any government department.

In an object-oriented design, you could implement this in different ways, such as:

- Having a single Address attribute that can store multiple addresses (e.g., a list or array)

Having a single address attribute that can store multiple addresses means the students have basically two types of address with current address and permanent address which need to be stored in the list or arrays.

- Creating a separate Address class with its own attributes (e.g., street, city, state, zip) and associating multiple Address objects with a Student object

When we create a class it is just like a table in the relation model and attributes are columns to store the multiple addresses with a single word or short data stores related to the address of the students such as: street no. 15, city = vikas colony, state = rajasthan, zip code = 240282. It is an example only, not a real address of any student. It only describes how the address looks like to store into the attributes for students (object) in the class in the object oriented database model.

The approach would depend on the specific requirements and complexity of the system being designed for the students objects attributes in the object oriented database model.
