php - Online Admissions System -

-

i working on online admissions system in mysql , php.

i need save applicant's personal academic details. far have created 1 table save personal details applicant id (auto increment) primary key. academic details bit confused. fields required academic details are:

degree level (like master, bachelor, high school); roll no; subjects;  grade; institution; percentage; degree image (image field save scanned copies of transcripts).

i not know how relate these 2 tables. uploading image files (scanned copies of transcripts) affect database performance?

you have 2 tables

applicants

id | name | address | etc, etc

academicdetails

id | applicantid | degree | rollno | degreeimageurl | etc, etc

to list applicants

select * applicants

to search specific applicant name.

select * applicants name = 'tom jones'

to select applicant id=1 , academic details use join

select * applicants join academicdetails on academicdetails.applicantid=applicants.id  applicants.id = 1
