# data/set/

This guide was generated by `xuda-cli`.

You can remove all generated folder guides later with:

~~~bash
npm run clean:readmes
~~~

Use this folder for Xuda `set_data` units.

## What belongs here

- create flows
- update flows
- delete flows
- reusable persistence logic

## Recommended blocks

- `<meta lang="json5">`
- `<params lang="json5">`
- `<datasource lang="json5">`
- optional `<fields lang="json5">`
- optional `<events lang="json5">`

## Important rules

- set persistence intent in `<meta>`, for example `crudMode`
- use params for values coming from components or other units
- keep save logic here instead of embedding record persistence directly in UI workflows

## Example

~~~xml
<meta lang="json5">
{
  id: "save_student_profile",
  menuTitle: "Save Student Profile",
  crudMode: "U",
  allowCreate: true
}
</meta>

<params lang="json5">
{
  in: {
    student_id_in: "string",
    full_name_in: "string",
    email_in: "string",
    campus_in: "string"
  }
}
</params>

<datasource lang="json5">
{
  type: "table",
  table: "student_profiles_table"
}
</datasource>
