Store the connection string in an environment variable, model the data using the member ID as the key and handle failures with reconnection. That way levels, economy and settings survive restarts. ## Why a database[](https://streethosting.com.br/en/guides/discord-bots/connect-discord-bot-to-database#por-que-banco) A bot without a database forgets everything on restart. Levels, balances for a [virtual economy](https://streethosting.com.br/en/guides/discord-bots/discord-economy-bot) and per-server settings need persistent memory. The database is that memory: it stores the data safely and handles many accesses at the same time. ## Which database to choose[](https://streethosting.com.br/en/guides/discord-bots/connect-discord-bot-to-database#qual-banco) MongoDB stores flexible documents and is widely used in bots because it is easy to get started with. Relational databases, like the ones you can set up with [MariaDB or MySQL on a VPS](https://streethosting.com.br/en/guides/vps/install-mariadb-mysql-ubuntu-vps), are great when the data has clear relationships. Choose based on the shape of what you store. ## Secure connection[](https://streethosting.com.br/en/guides/discord-bots/connect-discord-bot-to-database#conexao-segura) The connection string usually contains the database username and password. Never leave it in the code or in commits. Use an environment variable and treat it as a critical secret. ## Model the data[](https://streethosting.com.br/en/guides/discord-bots/connect-discord-bot-to-database#modelar) 1. Use the member ID as the primary key. 2. Store level, balance and settings tied to each user. 3. Separate data by server when the bot serves several. 4. Create indexes for the most frequent queries. Think about modeling before you grow. Reorganizing the data of thousands of users later is much more work than getting the structure right at the start. ## Resilience[](https://streethosting.com.br/en/guides/discord-bots/connect-discord-bot-to-database#resiliencia) * Connection string in an environment variable * Automatic reconnection on failure * Database access allowed only for the bot * Regular backup of the database data The database and the bot have to be up together. Keep everything online with [24/7 hosting](https://streethosting.com.br/en/guides/discord-bots/discord-bot-hosting-24-7) and, to run the bot and the database with room to spare, check out the [Ryzen VPS](https://streethosting.com.br/en/vps/ryzen) and the [bot plans](https://streethosting.com.br/en/bots).

It works for tiny prototypes, but it scales poorly and corrupts easily with simultaneous access. A database handles concurrency, queries and growth far more safely. MongoDB or a relational database? It depends on the data. MongoDB stores flexible documents and is popular with bots. Relational databases shine when there are clear relationships and structured queries. Choose based on the shape of your data and what your team knows well. Where do I store the connection string? In an environment variable, never in the code or in commits. The string usually contains the database username and password, so treating it as a secret is essential for security. Does the database have to be on the same machine as the bot? No. It can run on the same VPS for small projects or separately as you grow. Either way, allow access only to the bot and never expose the database to the whole internet.
