# Common Schema Patterns

Define reusable schemas for common record types.

``` python
from gdtest_sec_index_hero import validate

user_schema = {'name': str, 'age': int}
event_schema = {'type': str, 'timestamp': float}

assert validate(user_schema, {'name': 'Alice', 'age': 30})
assert validate(event_schema, {'type': 'click', 'timestamp': 1.0})
```
