Schema System

BaraDB uses a schema-first design with type inheritance and automatic migrations.

Defining Types

import barabadb/schema/schema

var s = newSchema()

let person = newType("Person")
person.addProperty("name", "str", required = true)
person.addProperty("age", "int32")
s.addType("default", person)

Type Inheritance

let employee = newType("Employee")
employee.setBases(@["Person"])
employee.addProperty("department", "str")
s.addType("default", employee)

# Resolve inheritance — Employee gets name, age, department
let resolved = s.resolveInheritance(employee)

Schema Operations

Diff

Compare two schemas:

let diff = s.diff(oldSchema, newSchema)

Migrations

Schema changes are tracked and can generate migration scripts.

Property Types

Type	Description
`str`	String
`int32`	32-bit integer
`int64`	64-bit integer
`float32`	32-bit float
`float64`	64-bit float
`bool`	Boolean
`datetime`	Date/time value
`bytes`	Binary data
