I'm trying to figure out how to create a simple RDBMS in C. I think the tables in the database could be implemented as arrays of structures. For instance, the statement:

struct users {

	char username[50];

	char password[15];

	char gender[1];

	int age;

} *table;

would be executed when the user of the database inputs:

CREATE TABLE users (

username VARCHAR(50),

password VARCHAR(15),

gender VARCHAR(1),

age INTEGER

);

The problem is that arrays and structures only last for the duration of execution, so I would need some way of writing the data to the hard drive. Is this possible? Sorry if this is a dumb question.

My thinking, off hand, is that you would do string parsing and a linked list of void *'s to build the tables structure.
