 !!! warning
     When using freeform views, the LLM typically gets raw access to the data source and can execute arbitrary operations on it using the query language of the data source (e.g., SQL). This can be powerful but also necessitates that the developer be extremely cautious about securing the data source outside of db-ally. For instance, in the case of Relational Databases, the developer should ensure that the database user used by db-ally has read-only access to the database, and that the database does not contain any sensitive data that shouldn't be exposed to the LLM.

 If you're not sure which method to choose, we recommend starting with the `MethodsBaseView`. It's simpler and easier to use, and you can switch to the `BaseStructuredView` later if you find you need more control over filter management. For this guide, we'll focus on the `MethodsBaseView`.

 ## Example
 Throughout the guide, we'll use an example of creating a custom base view called `FilteredIterableBaseView`. To keep things simple, the "data source" it uses is a list defined in Python. The goal is to demonstrate how to create a custom view and define filters for it. In most real-world scenarios, data would usually come from an external source, like a REST API or a database.
