# Design (Map)

The **Design** window allows you to define the script code of your **map** in relation to its source and destination data definitions. This script code is the logic that provides the transformation of data from the source to destination data definitions.

**Design** opens as a separate modal window, which means you are unable to use other **Statelake** windows until you close this window. If you minimise the window, you will find that you cannot use any other window.

::: info
When changing the source or destination data definitions on a **Map**, it will ask whether you wish to clear the current script code since the source or destination data definitions have changed. You will generally want to clear the mapping - however sometimes it is useful to retain the old script code as an indication to help you complete the **Map**.
:::

The **New Map** screen is split into five distinct panes beneath the search bar - **Source**, **Destination**, **Events**, **Scripting**, and **Compiler**.

The **Search** facility will seek out and identify the entered search term anywhere in the **Map** - and this includes the **Map** script, source and destination.
