title: Create/update/delete data on database
body: <p>I am new to using react, redux, and I have the following question. I have two Apps, an API, and a front-end App with react and redux. How can I create/update/delete a record? I know that I have to create a pure function in order to update my store, but where can I create/update/delete? I'm pretty sure that I don't have to modify my data using my dispatch (my actions), so I think I have to update my database record using reducer, but does this make my functions impure?</p>
