• Data Management

12
Data Management

• SQL Server 2005 Mobile Edition (SQL Mobile)
• Full featured database running locally on device
• inner/outer joins, transactions, locking, much
  more
• Visual Studio 2005 support
• Server Explorer
• Create database, tables and indices
• Modify schema and data
• Database file can be located on device or desktop
• Forms Designer
• Controls created directly from table schema
• Data view and edit forms can be auto generated

13
SQL Mobile Synchronization

• Remote Data Access (RDA)
• Merge Replication

14
Remote Data Access (RDA)

• Loosely-coupled
• Retrieve data from server and track local changes
• Send local changes back to server
• Very lightweight server cost
• requires URL pointing to DLL to allow data
  access. (i.e. http//192.168.1.100/sqlmobile/sqlc
  esa30.dll")

15
Merge Replication

• Tightly-coupled device and server schema
• Changes tracked on both device and server
• Device and server changes reconciled on synch
• Significant server cost
• DB File (.SDF) stored in a folder on the mobile
  device. (i.e. Data Source " foldername
  "RealEstate.sdf)

16
SQL Server Everywhere

• Essential relational database functionality in a
  compact footprint
• Ideal for mobile and desktop applications,
  including occasionally connected
• Embeddable in applications
• Free to download, develop, deploy, and
  redistribute

17
SQL Server Everywhere

• Increase Productivity SQL Server Everywhere
  allows developers and administrators to apply
  their existing SQL Server skills and be
  immediately productive.
• Enables Deep Business Insight SQL Server
  Everywhere, together with Business Intelligence
  in SQL Server 2005, allows you to extend your
  business insights further across the organization
  to distributed and mobile applications.
• Reliability For Mission-Critical Business
  Originally built on SQL Mobile technology, SQL
  Server Everywhere has self-healing and management
  technologies built designed to handle instant off
  and dead battery scenarios.
• Better Value Over Time As requirements and
  scale grow, SQL Server Everywhere can easily
  scale up to other editions of SQL Server.

18
Web Services Mobile Apps

• Web services perfectly suited for mobile apps
• Can communicate with any enterprise platform
• Well suited for casual connectivity
• Inexpensive way to roll-out mobile solutions
• Provide internet access to enterprise resources
• Accessing web services same as on desktop
• Visual Studio Add Web Reference generates proxy
• Proxy class handles communications details

19
