Understanding GraphQL Schema
The schema is a contract between client and server, defining how clients can access data.
#### Data Types
**Standard Types:** Int, Float, String, Boolean, ID.
**Custom Types:** Defining complex data structures. Custom types are user-defined and can include combinations of standard types.
