Advanced Domain Model Quiz

Advanced Domain Model Skills

• Inheritance enables sharing of behavior and structure across specialized entities.
• Generalizing the Player entity by the Person entity results in two separate tables.
• After generalizing Player and Staff entities by Person, their IDs remain unique to each table.
• A 1-1 association represents a HAS relation, while inheritance indicates an IS relation.
• Specializing FileDocument and Image entities improves security and properties based on specific usage.

Working with Data

• The default value for the DeleteAfterDownload attribute is false.
• Files or images are typically stored on the file server located on the application server.
• Indexes are most beneficial when there are more read than write actions.
• Applying an index increases the speed of read actions.
• Associations yield a list of IDs in the related object, as illustrated in provided images.

Advanced Security Configuration

• Structural changes and type changes in the domain model can affect database data.
• Data conversion involves four stages: clean model, model the conversion, deploy and convert, extend domain model.
• Redeploying the application after model cleanup prevents complex synchronization behaviors during later deployments.
• In XPath, the reversed() function changes the direction in which associations are queried.
• For self-references, the naming format "Apprentice_Buddy" is preferred for clarity.

Localization and Time Zones

• When localization is disabled, the displayed date in the client is based on UTC values.
• Localizing a DateTime attribute impacts both the client and application server.
• If both App and User time zones are defined, the client's display of localized DateTime depends on the client time zone.
