One of the most critical tasks that applications have to perform is
to save and restore data. Whether it be a word processing application
that saves documents to disk, a utility that remembers its configuration
for next time, or a game that sets aside world domination for the night,
the ability to store data and later retrieve it is a vital one. Without
it, software would be little more effective that the typewriter - users
would have to re-type the data to make further modifications once the
application exits.
Writing the code for saving data, however, can become boring repetitive work. First, the programmer must create a specification document for the proposed file structure. Next, the programmer must implement save and restore functions that convert object data to & from primitive data types, and test it with sample data. more...
