# SAIF.Business.Menu overview

> **Documentation context:** Packaged Component (NuGet)

`SAIF.Business.Menu` is the shared business-layer component that models menu pages, menu items, favorites, security-group assignments, and user-to-group memberships for the legacy SAIF presentation stack. Its primary responsibility is to return the authorized navigation menu for a caller by combining menu structure, security-group membership, public items, and favorites into a single read model.

## Purpose
- Provide the persisted menu definition used by presentation callers to render navigation.
- Compute each user's authorized menu from `MENU_ITEM`, `MENU_SECURITY`, `MENU_SECURITY_USER`, and `MENU_FAVORITE`.
- Support maintenance of lookup data, pages, items, favorites, and security-group assignments without owning any HTTP or UI concerns.

## Responsibilities
- Persist application-code and category reference data.
- Persist page definitions and menu items, including per-page flags and tooltips.
- Persist menu-item security-group assignments and user-to-group memberships.
- Return authorized menu projections and filtered views such as favorites and secured items.

## Key components
- `clsMenuAuthorizedItemCollection`: builds the authorized menu.
- `clsMenuItem` and `clsMenuSecurityCollection`: maintain items and their security groups.
- `clsMenuFavorite`: stores per-user favorites and order.
- `clsMenuPage`, `clsApplicationCode`, and `clsMenuCategoryCode`: supply lookup and page metadata.
- `clsMenuSecurityUser`: stores user-to-group memberships.
