Base Model

The BaseModel serves as the foundation for all models within your application, providing essential functionalities and features to interact with the database in an efficient and secure method.

It allows you to define basic rules for your models, like fields that are allowed to be inserted into the model database table, delete, or update. Additionally, it also supports flagging the model as read-only which limits the model to only perform select statements.
