This project aims to develop an application that functions as a network communication terminal manager, named prr. The program allows for the management and querying of clients, terminals, and communications. The application provides various services to its users, including:
Registering client information Registering terminal information Registering communication data Searching for past communications Calculating the balance associated with terminals
The application manages several entities:
Each client has a unique key, name (string), and fiscal identification number (integer). Clients can be associated with multiple terminals. They maintain information about payments made for past communications and current outstanding debts.
Clients are categorized into three types: Normal, Gold, and Platinum. The client type influences the cost of their communications based on tariff plans. The client type evolves according to specific conditions.
Each terminal is identified by a unique 6-digit numeric code (string) and is associated with a single client. Terminals can perform different types of communications, depending on whether they are basic or sophisticated.
Terminals keep their own accounting of payments and debts for communications. A terminal can also have a list of friend terminals, and communications between friend terminals are cheaper than communications between non-friend terminals.
Terminals have several states: Off, Silent, Wait, and Busy.
Each communication has a unique identifier (integer) and contains information about the source and destination terminals and the communication status (ongoing or terminated). Communications can be of different types: text, voice, or video.
The cost of a communication depends on its type and duration, calculated according to the client's tariff plan.
Tariff plans define the costs for each type of communication based on the client's type and communication type.
The cost of a communication is calculated based on the tariff plan applicable to the client and the communication type and duration.
