The Order Number field should be defined as an External ID and Unique field in Salesforce. This is because the Order Number is a unique identifier that comes from an external system and needs to be matched with the corresponding order records in Salesforce. An External ID field allows you to use the Order Number as a foreign key for data integration and upsert operations. A Unique field ensures that no two order records have the same Order Number in Salesforce. References:

 A lookup field creates a relationship that links one object to another object. The relationship field allows users to click a lookup icon to select a value from a popup list. The other object is the source of the values in the list1. In this case, the developer should add a lookup field on the Account object to the Global Address object, so that multiple Accounts can share the same Global Address as their default pickup address. This way, the Global Address object can store the common address information for different Accounts, and the Account object can reference the Global Address object via the lookup field. A master-detail field creates a parent-child relationship between two objects, where the master object controls certain behaviors of the detail object. The detail object inherits the sharing and security settings of its master object2. In this case, a master-detail field is not suitable, because the Global Address object should not be dependent on the Account object, or vice versa. The Global Address object should be able to exist independently of the Account object, and the Account object should be able to have multiple Global Address records associated with it. References:

 Salesforce CLI is a command-line interface that lets you run commands to create, test, and deploy Salesforce applications. You can easily integrate Salesforce CLI commands into various CI tools, such as CircleCI, Jenkins, or Travis CI, to automate testing and deployment of Salesforce applications against scratch orgs. Salesforce CLI also supports the Salesforce DX development model, which enables source-driven development, team collaboration, and agile delivery. References:

Scratch orgs are short-term Salesforce environments that you can spin up to work on a feature. They are source-driven, disposable, and fully configurable. To create scratch orgs, you need to use the Salesforce CLI, which is a command-line tool that lets you interact with Salesforce orgs and perform various tasks. You can use the Salesforce CLI to create a scratch org definition file, which specifies the features and settings of the scratch org, and then run the force:org:create command to create the scratch org. You can also use the force:org:open command to open the scratch org in a browser without logging in.

References: The use of Salesforce CLI to create scratch orgs can be referenced in the Salesforce Platform Developer I learning documents, specifically in modules that cover Salesforce DX and scratch orgs, such as:

• Scratch Orgs
• Develop in Scratch Orgs
