Customers (tenants) can use the application to search for apartments of their choice so that they can contact the owners for coordinating an appointment for viewing a specific apartment and renting. The application should keep track of the following data about the tenant (name, civil number of tenant, expire date of tenant civil number, mobile number, nationality, passport number, passport issue date, passport expire date). A tenant can rent more than one home, and a home can be rented to more than one tenant in different time periods.
