One of the options of InfoPath form template deployment, in SharePoint Server Enterprise, is by making it an Administrator approved form template. This can be done with any InfoPath form template, but is the required deployment option for form templates that have code behind them or are enabled for mobile devices. Deploying a form template in this way will make it available as a site collection feature throughout the SharePoint farm.

InfoPath form templates can be encompassed within a content type. The benefit of doing this is so you can reuse this content type within multiple libraries. If you later need to update the form template, you can update it in InfoPath and republish it to the content type and all libraries that are using this content type will get updated.

A fully functional InfoPath form with pre-built logic is published to a new form library in SharePoint. Each step of the publishing process is explained in this video.
