How it's better to store data from DB?

[Suliman via Digitalmars-d-learn]

Usually I am storing daba from DB as array of structures. 
Something like:

struct MyData
{
  int id;
  string name;
  int age;
}

MyData mydata;

Then I am creating array of structures:
MyData [] mydatas;

And fill data in my code. Then append it to `mydatas` to get it 
iterable.

But is it's good? Maybe there there is better way?

I need main -- be able iterate thru the data. Any other variants?
