Not clear, too general question. It depends.

I have to agree, your question isn't clear: what is the file processing you need to do?

Solution 1

Parse the source file and store it in a database.
Perform all processing operations on the database table rather than the source file.

An option is Object Serialization[^] a very powerful and elegant mechanism.
All the programming languages you tagged support such technique (C++ via 'external' libraries, like MFC: in fact serialization is one of the good things of MFC).
Using object serialization the proper data structure for the student details would be, precisely, a Student class and you would have as many instances of such class held by a container of your choice (for instance, using C++, a std::vector) whenever needed, the serialization mechanism would provide the way to load from file (or store to file) the container content.
