# Customizing logical models for Insight Advisor

Business logic enables you to customize how Insight Advisor interprets your application data when generating analysis from queries.

Business logic defines how Insight Advisor interprets your data and handles alternative terms for values in your data model with:

* Insight Advisor Search

* Insight Advisor Analysis Types

* Insight Advisor Chat

* Associative insights

Tip noteFor information on business logic and Qlik Answers, see [Optimizing your application for Qlik Answers with business logic](https://help.qlik.com/en-US/cloud-services/Subsystems/Hub/Content/Sense_Hub/QlikAnswers/BusinessLogicAI/business_logic-qlik-answers.htm).

Insight Advisor relies on the Qlik cognitive engine and learned precedents to understand the relationships and uses of fields in your data model. You can optionally customize the logical model used by Insight Advisor for an application. You can add vocabulary to your business logic that helps Insight Advisor handle alternate terminology users might use when querying Insight Advisor.

You can customize the following areas of business logic in Qlik Sense:

* Logical model: Customize the fields and groups used in the model, create packages, define field hierarchies, and set behavior.
