Start with requirements gathering and analysis with the users to find out, among other things,
1. Who and What are involved: Teacher, Student, Subject, etc => Entities
2. What are their relationships: e.g. every teacher can teach multiple subject, every teacher can teacher many students, etc => Relationship
3. What data do they capture, any system, documents (forms, letters) they use to do this job currently? => Reveal data attributes and existing work flow.
4. What are other other requirements.
It is impossible to explain the design of a database here, you may refer to Introduction to database design[^]. It is a matter of trials and errors, but you get better with more practice. Always go through your design with the users until they are satisfied.

Create a master table for both like teachers,students,subjects,etc.u can use id for concatenation for each table don't use name.

Eg:

Subject master table:

Id        Subject
--        -------
1         English
2         Maths

Teacher master table:

Id        Teacher_Name
--        ----------
1         Sruthy
2         Sreelakshmi

Students master table:

Id        Students_Name
--        ------
1         Vimal
2         Tadit
