You want your data to be normalized in your Redux store. Now if your data is relational, your state is bound to look like tables in a relational database, because that's the normalized way to represent that kind of data. As you write your Redux reducers and selectors, you want to divide them to small functions to create a hierarchy of functions. This makes the functions easy to test and reason about, and is one of the great things about Redux. You might have a reducer for a list of entities, lets say restaurants. To store information about restaurants, you have an items array of restaurant id's, and an itemsById map. In the main restaurant reducer, you delegate to separate items and itemsById reducers. You create another subreducer inside itemsById reducer that applies updates on individual restaurants' attributes. That works great until you need to access employee entities related to that restaurant. The state supplied to your restaurant reducers doesn't have information about employees.
