please draw the relational model for this :
The structure consists of several fields, each of which acts like a variable. Say you have a structure with two integer fields, x and y. You want to assign the value of x to a variable. What information flow constraints must be satisfied? Similarly, if you want to assign the entire structure to another, what information flow constraints must be satisfied? The question requires us to initialize a structure by ourselves, then we assume an assignment for this structure and consider what constraints this information flow must be satisfied. Here is an example structure in C:struct xyzzy {int firstfield;char secondfield[10];char *thirdfield;float fourthfield;};
