Enterprise Application Structure Patterns

Subject : it-skills
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A view that proceses domain data element by element and transforms it into HTML.






2. A subclass that provides special behavior for particular cases.






3. An object that encapsulates access to an external system or resource.






4. Allows framework or layer supertype code to acquire offline locks.






5. An object that carries data between processes in order to reduce the number of method calls.






6. An object that handles a request for a specific page or action on a Web site.






7. Has one class perform the database mapping for a child class.






8. Represents a monetary value.






9. Provides a coarse-grained facade on fine-grained objects to improve efficiency over a network.






10. Keeps the session state on a server system in a serialized form.






11. Maps an object into several fields of another object's table.






12. Mediates between the domain and data mapping layers using a collection-like interfacefor accessing domain objects.






13. An object model of the domain that incorporates both behavior and data.






14. Renders information into HTML by embedding markers in an HTML page.






15. Prevents conflicts between concurrent business transactions by allowing only one business transaction at a time to access data.






16. Saves the database ID field in an object to maintain identity between an in-memory object and a database row.






17. Represents an inheritance hierarchy of classes with one table per concrete class in the hierarchy.






18. Splits user interface interaction into three distinct roles.






19. A small simple object - like money or a date range - whose equality isn't based on identity.






20. Organizes business logic by procedures where each procedure handles a single request from the presentation.






21. Defines an interface in a seperate package from its implementation.






22. Stores session data as commited data in the database.






23. Represents an inheritance hierarchy of classes with one table for each class.






24. Saves a graph of objects by serializing them into a single large object (LOB) which stores it in a database field.






25. Represents an inheritance hierarchy of classes as a single table that has columns for all the fields of the various classes.






26. Links classes during configuration rather than compilation.






27. An object that acts as a Gateway to a database table. One instance handles all the rows in the table.






28. Saves an association as a table with foreign keys to the tables that are linked by the association.






29. Maps an association between objects to a foreign key reference between tables.






30. An object that sets up a communication between two independent objects.






31. A layer of Mappers that moves data between objects and a database while keeping them independent of each other and the mapper itself.






32. An object that doesn't contain all of the data you need but knows how to get it.






33. An object that represents a database query.






34. A well-known object that other objects can use to find common objects and services.






35. Prevents conflicts between concurrent business transactions by detecting a conflict and rolling back the transaction.






36. An in-memory representation of tabular data.






37. Turns domain data into HTML in two steps: first by forming some kind of logical page - then rendering the logical page into HTML.






38. A centralized point for handling screen navigation and the flow of an application.






39. A structure to organize database mappers that handle inheritance hierarchies.






40. Locks a set of related objects with a single lock.






41. An object that wraps a row in a database table or view - encapsulates the database access and adds domain logic on that data.






42. A type that acts as the supertype for all types in its layer.






43. A single instance that handles the business logic for all rows in a database table or view.






44. Ensures that each object gets loaded only once by keeping every loaded object in a map. Looks up objects using the map when referring to them.






45. Stores session state on the client.






46. Removes dependence upon problematic services during testing.






47. An object that acts as a Gateway to a single record in a data source. There is one instance per row.






48. An object that sets up a communication between two independent objects.






49. Defines an application's boundary with a layer of services that establishes a set of available operations and coordinates the application's response in each operation.






50. Maintains a list of objects affected by a business transaction and coordiantes the writing out of changes and the resolution of concurrency problems.
