# CRM Analytics in Apex

Build and execute queries and retrieve lens and template data using CRM Analytics Apex classes and methods.

CRM Analytics in Apex currently consists of the `executeQuery` method, the `Wave.QueryBuilder` class, and the `Wave.Lenses` class.

`ConnectApi.Wave.executeQuery`

Use the `executeQuery` function (exposed through the ConnectApi namespace) to pass a SAQL query from an Apex page to CRM Analytics, and get a response in the form of JSON.

`Wave.QueryBuilder`

The `QueryBuilder` class is the most convenient, preferred, and safest way to construct a SAQL query string for execution.

`Wave.Lenses`

Retrieve a collection of CRM Analytics lens assets and describe a single lens asset.

`Wave.Templates`

Retrieve a collection of CRM Analytics templates, describe a single template and template configuration.
