Explanation
Google Analytics requires a system connected to the Internet in order to collect data. So, it cannot collect data from an Offline inventory database. Google Analytics can collect data from websites by pasting a tracking code in the website HTML code. Google Analytics can also track your mobile apps using Google Analytics by using the Firebase SDK that connects with your app and provides analytics data to your Google Analytics account. You can also connect an online Point Of Sales system(POS) using POS software that integrates with the Firebase SDK to collect data from online POS systems.
