HOME RENTAL APPLIANCE SYSTEM

• Programming language (C#)
• Database (MsSql)
• I'm linking the database from C# using connectionString. So, when you run this program, you must change the serverName infront of the connectionString to your MsSql Server Name. You can get your serverName in Sql Management Studio. If you are not configured connectionString, you will get an error :( .

Introduction

The Home Appliance Rental System is an innovative solution designed for renting electrical appliances ranging from small to large for a minimum of one month. The system is accessible to two types of users: the administrator and the customers. The administrator has the authority to carry out various functions such as viewing, adding, editing, deleting and updating, while the customers can only view and rent. To use the system, both types of users must first register successfully. Upon registration, users can log in using their username and password. The system enforces strict password requirements, where the password must contain characters between 8 and 16, at least one uppercase and one lowercase letter. It is mandatory for both users to remember their login details to access the system. The implementation includes a well-defined design, thorough implementation and employs special methods such as encapsulation to ensure the system's efficiency. Additionally, testing has been carried out to ensure that the program can handle human errors effectively. Lastly, a detailed class diagram with explanations is provided to enhance the system's usability.
