The first simple hotel management system was introduced back in the 1970s, allowing hoteliers to confirm on-site reservations. By the early 1990s, the first database management system was marketed, allowing for digital records, which made accessing information much easier than Excel spreadsheets. Now, the hospitality industry is amidst the "cloud computing boom". The impact of cloud-based solutions is enormous: it revolutionises how the managers run their hotels/restaurants and interact with the customers.
