Mnesia Tutorial Guide

To get started with Mnesia, you’ll need to download and install the OTP. Once installed, you can follow these steps to create a new Mnesia database:

1. Create a new directory for your Mnesia database.
2. Initialize the Mnesia database using the `mnesia:start()` function.
3. Create a new schema using the `mnesia:create_schema()` function.
4. Load the schema into the Mnesia database using the `mnesia:load_schema()` function.

How to Use Mnesia

Once you have created a new Mnesia database, you can start using it to store and retrieve data. Here are some basic operations you can perform:

• Inserting Data: Use the `mnesia:write()` function to insert new data into the database.
• Retrieving Data: Use the `mnesia:read()` function to retrieve data from the database.
• Updating Data: Use the `mnesia:update()` function to update existing data in the database.
