# Connecting to the Database

To start working with my ORM system, you need to set up a database connection. Below is an example of connecting to a PostgreSQL database.<br>

An example of connecting to PostgreSQL:

```typescript
import {DatabaseManager, DatabasesTypes, DataSourceContext} from "@myroslavshymon/orm";

// Створення екземпляру DatabaseManager для PostgreSQL
export const databaseManager = new DatabaseManager<DatabasesTypes.POSTGRES>(
    {
        type: DatabasesTypes.POSTGRES,
        host: 'localhost',
        user: 'postgres',
        password: 'xxx',
        port: 5432,
        database: 'first',
        models: [
            Users,
        ],
    },
    new DataSourceContext()
);

// Створення ORM підключення
(async () => {
    await databaseManager.createOrmConnection()
})();
```

**Configuration Parameters**

* `type`**:** The type of database (MySQL or PostgreSQL).
* `host`**:** The address of the database server.
* `user`**:** The username for connecting to the database.
* `password`**:** The password for connecting to the database.
* `port`**:** The port on which the database is running.
* `database`**:** The name of the database.
* `models`**:** An array of models that will be used in your ORM system.

**Code Description**

1. **Importing Required Modules:** First, import the necessary modules from your ORM library.
2. **Creating an Instance of DatabaseManager:** An instance of DatabaseManager is created, where the database connection parameters are specified.
3. **Creating ORM Connection:** The `createOrmConnection` method is called to establish the connection to the database.

This code allows you to quickly set up a database connection and start working with my ORM system.
