Are you creating this database using source code or are you using a program?
If you are using a program, what program?
If you are using source code, on what platform do you intend on using the database?

Solution 1

Your drive space, and the the operating system define the limits of the maximum file size.

Assuming you're running Windows Vista or Windows 7, your file size can go into the terabytes.

This isn't really a C++ question though.

"what are the factors to define maximum size for a file?"

You need to compute the data size for one record in your database. (i.e. sum of the size of each field,)

Then your check what are the requirements for your database, what is the number of records your database should hold, then just compute the maximum size you will need.

When that is done, you will have to decide the best method to handle that amount of data.

Max.

The theoretical limit on NTFS is 16 TB (minus a few KB).
