# SAIF.Business.CustomerContact overview

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

`SAIF.Business.CustomerContact` is a packaged BOF business library that manages customers, contacts, reusable communication records, and customer-contact relationships, while also translating several external business identifiers into local customer/contact records.

## Purpose
- Provide BOF aggregate roots for customer and contact data, including notes and reusable address, email, and phone records.
- Support combined customer/contact search, relationship maintenance, code-table hydration, and external-ID conversion workflows used by higher SAIF business layers.

## Responsibilities
- Persist `COMPANY`, `PERSON`, and `COMPANY_PERSON` business data through BOF criteria classes.
- Manage standalone address, email, phone, and note records plus their customer/contact association rows.
- Translate agencies, agents, auditors, groups, providers, policies, RTW codes, and injured workers into local identifiers.
- Provide cached code-map helpers for email and phone type descriptions.

## Key components
- `clsCustomer` / `clsContact`: root BOF aggregates for customer and contact persistence.
- `clsCustomerContact`: customer-to-contact relationship maintenance.
- `InfoItems\clsAddressInfo`, `InfoItems\clsEmailAddressInfo`, `InfoItems\clsPhoneInfo`: reusable communication and address records.
- `clsCustomerContactSearch`: combined search request validation and result composition.
- `mdlCustomerContact`: external-ID conversion and helper workflow module.
- `mdlCodeMaps`: localized code-table hydration and caching helper.
