SimpleStorage Data Type in StorageFactory.sol

[maxdporter]

For this code in the StorageFactory.sol file:
**_contract StorageFactory {

SimpleStorage[] public simpleStorageArray;

function createSimpleStorageContract() public {
    SimpleStorage simpleStorage = new SimpleStorage();
    simpleStorageArray.push(simpleStorage);_**

I don't understand the "SimpleStorage" data type. From the previous lesson, we created a struct called "People" and defined it. We then initialized an array for it.

But in the StorageFactory.sol, SimpleStorage isn't a defined variable, (or is it?)

Hello @maxdporter well this is an object, as you know we have created the first contract called SimpleStorage, and now in our StorageFactory we import it with import "./SimpleStorage.sol"; so we can use that contract as a data type (actually is an object) .
