What is one way to perform actions in the Salesforce database?

Building or installing an Apex action is a valid way to perform actions in the Salesforce database because Apex is a strongly typed, object-oriented programming language that allows developers to execute flow and transaction control statements on the Salesforce platform's server in conjunction with the Salesforce database. Apex can be used to manipulate data, perform complex logic, and trigger events when certain conditions are met, thus effectively interacting with the database.

When using Apex actions within Salesforce, you can create code that can insert, update, delete, or retrieve records in the database. This method provides a flexible way to automate business processes and handle database interactions more efficiently than using point-and-click tools alone.

Other options may involve data handling in different capacities but do not focus directly on executing actions within the database itself. For instance, executing a database query is limited to retrieving data rather than modifying it. Creating a custom object involves setting up new data structures but does not directly perform actions. Similarly, using an API Key generally pertains to authenticating and connecting to external systems rather than executing actions directly within the Salesforce database.
