<p>What is the difference between Object-Oriented Modeling and Object-Oriented Programming? I overheard a conversation on my subway train this morning and it seems that these things are different. Aren't they?</p>
| <p>I'd say the modeling precludes the programing, where the modeling is the physical design, before the programming is implemented.</p>

<p>Is there a way to consume a web service using JavaScript? I'm Looking for a built-in way to do it, using a JavaScript framework is not an option. </p>
| <p>You can consume a web service using JavaScript natively using the XmlHttpRequest object. However instantiating this object varies between browsers.

<p>I'm designing a system which is receiving data from a number of partners in the form of CSV files. The files may differ in the number and ordering of columns.
