title: What are the ways to store array data on a local drive?
body: <p>I want to store information about up to 1000 streets (the name, the ID and a short info, up to 500 characters). The right thing to do, seems to be to create class <code>Street</code> with three needed fields and create a <code>List</code> or an <code>array</code> of them. However,  I need to store (and edit, from time to time) all this data on user's computer. What are the ways? Storing such big arrays in <code>.txt</code> files seems to be inconvenient.</p>
