In modern backend applications, many programming languages can be chosen, including Go—a programming language that provides high performance with concise syntax and can also be used to develop backend applications, including REST API and GraphQL applications. This course will cover many tools that can be used to develop a backend application, including fiber for REST API application, gqlgen for GraphQL application, and apitest for testing purposes.

In this course, you’ll learn about the main concepts of web applications, including HTTP, REST API, databases, and GraphQL. You’ll cover how to develop a backend application and deploy the application as well. 

By the end of the course, you’ll be able to develop a backend application using REST API and GraphQL approach. Also, you’ll be able to test and deploy the backend application that has been developed.

Create a `resources` table with these columns:

- `id`
- `name`
- `age`
- `salary`
- `division_name`

1. Create a `divisions` table with these columns:

- `id`
- `name`

2. Create an `hr` table with these columns:

- `id`
- `name`
- `age`
- `salary`
- `division_name`
- `division_id`

1. Create a `divisions` table with these columns:

- `id`
- `name`

2. Create a `human_resources` table with these columns:

- `id`
- `name`
- `age`
- `salary`
- `division_name`
- `division_id`

1. Create a `divisions` table with these columns:

- `id`
- `name`

2. Create a `human_resources` table with these columns:

- `id`
- `name`
- `age`
- `salary`
- `division_id`

A company called Cool Company wants to manage its human resources. The company wants to view the basic information of the resource including name, salary, age, and division. What kind of tables can be created based on this scenario?

Which query is used to create a new database?

Which query is used to create a new database?

1. Use the database:

```sql
USE university;
```

2. Create the table:

```sql
CREATE TABLE courses(
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(255) NOT NULL,
    code VARCHAR MAX=6 NOT NULL
);
```

1. Use the database:

```sql
USE university;
```

2. Create the table:

```sql
CREATE TABLE courses(
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(255) NOT NULL,
    code VARCHAR(5) NOT NULL
);
```

1. Use the database:

```sql
USE university;
```

2. Create the table:

```sql
CREATE TABLE courses(
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(255) NOT NULL,
    code VARCHAR(6) NOT NULL
);
```

1. Create the table:

```sql
CREATE TABLE courses(
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(255) NOT NULL,
    code VARCHAR(6) NOT NULL
);
```

A database called `university` is created, but the table for storing courses is not created. The course data that will be stored are names and codes. The code of the course must not be longer than six characters. Which of these queries is suitable to create the table for the course data?
