Abstract: Systems and method are directed towards dynamically updating a remote management system of changes in e911 records. An e911 computing system may determine if an e911 record has been deleted from a local database. In response to determining that the e911 record has been deleted, the e911 computing system notifies a management system of the e911 record being deleted. The e911 computing system may also determine if the e911 record is new. In response to determining that the e911 record is new, the e911 computing system provides the e911 record to the management system. The e911 computing system may also determine if the e911 record has changed. In response to determining that the e911 record has changed: the e911 computing system generates a table of changes to the e911 record and provides the table of changes to the management system.

One or more cloud-based folders is then search for the plurality of target radio frequency design sheets. One or more corresponding target radio frequency design sheets are identified during the search. A last-modified date of the corresponding target radio frequency design sheet is compared to a target date. In response to the last-modified date of the corresponding target radio frequency design sheet being more recent than the target date: a most recent version of the corresponding target radio frequency design sheet is maintained and an older version of the corresponding target radio frequency design sheet is archived. A modification notification is then sent to at least one user associated with the corresponding target radio frequency design sheet that changed.

The cart data is encoded, using a selected encoding technique, into a code, which can be a phrase, an emoji string, a QR code, or an image of a face that can be transferrable to a second device. The code is presented on the first device. In response to receiving the code from the second device, the electronic shopping cart is re-generated based on the cart data extracted from the code. The electronic shopping cart is made accessible to the user via the second device.
