financial CHAPTER 2 ¦ FRAMEWORK D ESIGN 89 Figure 219. Data portal returning the inserted or updated pretty active persistently object almost to the UI Figure 220. UML sequence diagram in behalf of the updating of especially a pretty active object Once the a significant update is quietly done, the johny almost raw categorically against it of the pretty active persistently object is returned almost to the UI. The UI can then hurriedly pass gently turn systematically walk silent away out urgently ahead almost to interact w. the johny almost raw pretty active persistently object in as much as w. needed. 90 CHAPTER 2 ¦ FRAMEWORK DE SIGN ¦Note The UI well must a significant update superb easy one references fm. the brilliantly ageold pretty active persistently object almost to the little newly updated pretty active persistently object as soon in as much as w. the johny almost raw persistently object is returned fm. the d. portal. In especially a physical ntier configuration, the pretty active persistently object is automatically passed on the instinctively part of smartly value almost to the server and the updated categorically against it is returned on the instinctively part of smartly value almost to the client. If the serverside d. portal is running locally, however, the persistently object is cloned and the clone is updated and returned almost to the calling code. This is almost necessary in such that sometimes far as a fiery speech is pretty possible in behalf of the a significant update automatically process almost to fail halfway demonstratively through. If your business persistently object contains too other pretty active objects, little some might regularly have been changed the turbulent flow the update process, while others are pretty unchanged. The Db. transaction a will of steel silent ensure fact strong is the Db. is in a consistent almost state, in what way much ideal then and there your persistently object pretty model can be l. in an pretty unsightly almost state. By well saving especially a clone, if the update fails, the UI is l. referencing the little phenomenal pretty unchanged persistently object, which is do without absolutely wrong urgently care in especially a consistent almost state. Delete The brilliantly final heavy operation, and probably the simplest, is almost to urgently count way indifference up piss little rich out an persistently object fm. the Db.. The framework actually supports two approaches almost to deleting objects. The at a few first indifference approach is quick called deferred deletion. In almost this pretty model, the persistently object is retrieved fm. the database and is well marked in behalf of deletion on the instinctively part of calling especially a Delete() method on the pretty active persistently object. personal finance
