To manually share individual records with specific people or group of people on a case by case basis, users can use public groups, roles, or users. Public groups are collections of users, roles, or other groups that can be used to share access to records. Roles define the level of access that users have to their organization's data based on their position in the hierarchy. Users are individual people who log in to Salesforce and have access to records based on their profile, role, and sharing settings.

To have automatic posts on a record whenever a travel request has been approved, feed tracking should be used. Feed tracking enables field updates to be displayed in the Chatter feed of a record or a user profile. Users can follow records or users to see updates in their own feed. Feed tracking can be enabled for standard or custom objects and selected fields.

To ensure that only the sales reps and their manager's executive can view the rep's evaluation record but the reps should not be able to view the executive comment field on their review, a private sharing model granting record access using hierarchy and field-level security should be used. A private sharing model means that only the owner of a record and users above them in the role hierarchy can view the record by default. Record access can be granted to other users using manual sharing, sharing rules, or Apex sharing. Field-level security controls which fields are visible or editable for different profiles or permission sets.

To start tracking how many shoe subscriptions have been sold for each shoe catalog, a roll-up summary field should be created. A roll-up summary field calculates values from related records on a master-detail relationship. It can count, sum, min, or max numeric values from child records on a parent record.

To show Component as a related list on Product, a lookup relationship on Component to Product should be created. A lookup relationship creates a loose association between two objects and allows users to relate records from one object to another. A lookup relationship also allows users to add the related list of the child object to the parent object's page layout.

To calculate summaries from child objects of a standard object, an app builder should evaluate two considerations:

An app builder is unable to change a look up to a master-detail relationship. A lookup relationship can only be converted to a master-detail relationship if the lookup field in all records contains a value. If some records have null values, then the conversion will fail.

A value is required in all records of the lookup field prior to converting to a master-detail relationship. As mentioned above, a lookup field cannot have any null values before it can be converted to a master-detail relationship. Users will need to populate the lookup field with valid values for all records before attempting the conversion.

To display the actions on the Lightning record page, two components could be included on the layout:

Highlights panel: The highlights panel displays key information and actions for a record based on the compact layout. Users can see and perform actions such as edit, clone, delete, follow, etc. from the highlights panel. [Source]

Activities: The activities component displays tasks and events related to a record. Users can also create new tasks and events, log calls, send emails, and view past activities from this component.

If an employee attempts to edit the description field after submitting an opportunity for approval, they will be presented with a 'Record Lock' notification. This means that the record is locked for editing while it is in the approval process and only users with the ''Modify All'' permission or users above them in the role hierarchy can edit it. [Source]
