# Data Field Types

## Overview

In the system, whether it's customer data, work orders, or other related information, you will find many different types of fields available. These field types include text, numbers, dates, etc.; each corresponds to specific data processing requirements and directly affects functionality implementation and interface display.

For example, when creating an import template, the system provides these different field types for you to choose from so you can configure them according to your needs.
