Data Management

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


SQL Mobile Synchronization


Remote Data Access (RDA)



Merge Replication



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/sqlcesa30.dll")


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“)


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

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:
