The Attnor application aims to create a database showing evaluations of the experiences of lessors with the tenants who have previously dealt with them by using the global stars system for evaluation in addition to the system of asking questions and answering them with yes first without offending the tenant person, so that the lessor is concerned with investigating the appropriate tenant who wishes By dealing with him, in order to save money, time and effort, bearing in mind that this database is built by the lessors themselves and depends on their personal experiences. Thus, the lessor can choose the tenants whom he wants to deal with, based on the previous experiences of others, and he can evaluate his experience with the tenant who dealt with him so that others can benefit from this evaluation.
