Controle de Acesso(Acess Control)

(Português do Brasil)

Estou fazendo um controle de acesso com senha e RFID, o projeto em sua parte física já está pronto e já fiz uma programação funcional.
Estou usando um Arduino Mega 2560, um LCD 16x2, um módulo relé X4, um teclado 3x4 e um leitor RFID-RC522.
Como sou um pouco iniciante na programação do Arduino, gostaria de saber como poderia fazer para por exemplo cadastrar ou excluir um cartão sem ter que mexer na programação, tipo criar um Banco de Dados e consultá-lo.
Alguém poderia me ajudar e explicar como posso fazer isto??

Obrigado, Everton

I'm doing an access control with password and RFID, the project in its physical part is already done and I've done a functional programming.
I'm using an Arduino Mega 2560, an LCD 16x2, a relay module X4, a 3x4 keyboard, and a RFID-RC522 reader.
I'm rather novice in programming of the Arduino, I wonder how I could do for eg registering or delete a card without having to tamper with the programming and how to create a database and query it.
Could anyone help me and explain how can I do this?

Thanks, Everton

Build that in in the first place.

and how to create a database and query it.

How many entries do you need, in how many tables, with how many columns, containing what kind of data.

I think you have some unrealistic expectations regarding what you can do on the Arduino.

Hi, apparently you did not understand my question. I asked how I can use a database to record the data from a card, look at them and delete them, of course if possible. Thank you.

No, you didn't. You did NOT say what the database was for.

Anyway, where do you intend to store this data, and for how long? And, you still haven't answered the question of how much data. There is a world of difference between storing data fro 10 tags and data for 10,000,000 tags with user names, e-mail addresses, photos, and other data.
