Database Structure

Yooz stores data in .yooz files using a hierarchical, multi-layered structure. Data can be organized in any order, mixing key-value pairs with nested layers at different levels.

Data Format:

• Keys are marked with +

• Values are marked with -

• Each layer is enclosed in parentheses ()

Example Structure:

(
  +name
  -mohammad
  (
    +country
    -iran
  )
  +age
  -22
)
