# SchemaJS Global

`globalThis.SchemaJS` is a global object in **SchemaJS** that serves as the primary interface for interacting with the database environment. It provides access to essential APIs and tools, such as the `QueryBuilder`, `Table`, and `Column` classes, as well as utility methods like `query` for executing database queries. By attaching these core functionalities to the global scope, **SchemaJS** allows developers to easily build, query, and manage database tables and schemas within any JavaScript environment, ensuring that the database context and operations are accessible throughout the application.

```typescript
const { Table, Column, .. } = SchemaJS;
```
