41. Возможности синхронизации БД
DAT306
Возможности синхронизации БД
Фокус на администратора баз данных, специфично для SQL Server
Богатый набор возможностей, мало программного контроля
Merge Replication
Фокус на разработчиков - Sync Runtime
Синхронизация данных, а не замена записей БД
Компонентная, SOA ориентированная инфраструктура
Поддержка любого ADO.NET Provider
Дополнительные возможности с SQL Server 2008
ADO.NET Provider for the Microsoft Sync Framework
Sync Services for ADO.NET
Доступно только с SQL Server Compact
Фокус на разработчиков, простота, ограниченные сценарии (download w/incremental upload)
Sync Services for ADO.NET позволяет работать с такой же простотой, но с большей масштабируемостью
Remote Data Access (RDA)

42. Доступ к данным в ADO.NET
DAT306
Доступ к данным в ADO.NET
Запрос к серверу
DataAdapter.SelectCommand вызывается, возвращая DataSet
Изменения делаются в RAM над DataSet и возвращаются назад
DataAdapter преобразует изменения в Insert, Update and Delete команды
DataAdapter
SelectCommand
Server DB
InsertCommand
Connection
Forms
UpdateCommand
DeleteCommand
Работа через сервисы
Операции приводят к запросу к серверу
Частичное использование клиента – операции в RAM
Неустойчиво к проблемам в сети

46. Сравнение с SQL Server Express
9/20/2018 2:13 PM
Сравнение с SQL Server Express
SQL Server Compact
SQL Server Express
Для чего
Ключевой функционал БД в компактном исполнении
Идеален для малых серверов и desktop где нужен более богатый функционал - full text search и мощная поддержка XML в БД
Идеален для мобильных устройств, когда подключение происходит периодически
Легкая миграция на Workgroup, Standard и Enterprise редакции
Внедряется в приложение
Бесплатен
Не для
Работы как сервиса
Когда нужно минимальное использование памяти
Работы сервера для нескольких пользователей
in-process решений
Когда нужен более полный функционал SQL Server
Работы на мобильных устройствах
