Agenda

SQL Server CE Overview

SQL Server CE v2.0 Architecture and Features

Deployment and scaling case studies

SQL Server CE v2.0 release and licensing

SQL Server CE PositioningKey Scenarios – Occasionally connected data access

Sync database over high speed conectionCradle, 802.11b, or Ethernet

Use application offlineSubsequent sync in field via slower connection

GPRS, dial-upMS Mobile Scenarios

Mobile Web FormsAlways connectedWide device support (over 300), including PalmLimited UI

ADO.NET Data SetUtilize XML web servicesNo RI, QP, ability to query across data setsNot designed for large data setsNo compression on syncLimited sync and trackingSync to any backend database via XML

SQL Server CEQP, RI, query multiple tablesCompression on syncBuilt in tracking, strong sync to SQL Server Encryption
