2. DEV351 Developing Local and Mobile Data Solutions with SQL Server Everywhere Steve Lasker Program Manager / Technical Lead Microsoft Corporation UI Framework http://blogs.msdn.com/SteveLasker

3. Agenda App evolution Why SQL Server Everywhere VS Designer support SQL Server Everywhere enhancements over SQL Mobile Deployment options for SQL Ev Programming Model ADO.NET, ResultSet, LINQ to Entities w/SQL Ev Securing the stolen laptop

4. Basic Components of An App Interaction Model User Interface Service (Web Service, CMD Line) Logic Security, rules, defaults, workflow Persistance Data (Database, XML, Data Device)

5. Evolving Applications

6. Microsoft Exchange MS Expense Bank Accounting Payroll MS Expense Owned by different teams and/or companies Version independently of each other Don’t necessarily know, or care, about each client Delegate responsibility to the next app / tier

7. Fully Partitioned Applications OCS Services Create complete components Delegate responsibility Empower decision making w/reference data & rules Communicate complete operations

8. Evolving Applications OCS Services

9. Right tool for the right job

10. Local Database Options Server (1000’s of users) Workgroup (Dozens of users) Desktop (Single User) Laptop Tablet PC Windows CE Device Pocket PC Smartphone Win 32 SQL Mobile SQL Express SQL Server SQL Server Everywhere Multi User Single User Scenarios

11. Which Version of SQL Server? Enterprise Server Workgroup Server Desktop, Workstation Laptop PocketPC TabletPC SmartPhone Fully featured database serving dozens to thousands of users Data as a service for small, multi-user client apps and websites requiring advanced SQL Server features Ideal for single user client and device applications requiring a maintenance free, compact footprint

12. SQL Everywhere - SQL Express SQL Server Everywhere SQL Server Express When to use / benefits Essential relational database functionality in a compact footprint Ideal for mobile and desktop applications, inc. occasionally connected Embeddable in applications Free to download, develop, deploy, and redistribute Ideal for small server deployments as well as desktop applications with more rich requirements such as full text search and powerful XML query processing. Seamless upgrade to SQL Workgroup, Standard and Enterprise Free to download, develop, deploy, and redistribute When not to use When you want to run as a service When you need a multi-user database server You need the full functionality of SQL Server When the footprint and memory requirements need to be compact When you want to run in process When you want to target devices

13. SQL Ev Notable Features 1.4 MB runtime Smaller then a floppy disk Admin and Non-Admin deployment options Single file, code free format (.sdf) In-Proc with the hosting app Doesn’t run as a service Up to 4 gigabytes per database Multi connections for background data operations Simplified security with password and encryption Query Processor w/Transaction Runs on Windows XP, Windows 2003, Vista B2 Windows Mobile Common programming model through ADO.NET Multiple sync options Proven, Lightweight, 2 Tier, Scalable Sync API (RDA) Full Featured Merge Replication Future investments for Occasionally Connected Apps

14. SQL Server Everywhere Non Features Sprocs, Views, Functions Database is in-proc with the app Why limit yourself to TSQL Write your functions in full managed code Triggers Interesting scenarios, but triggers are limited to TSQL Code How about event notifications? (Future) Complex user role management Data is pre-partitioned per user Network connectivity Not supported for IIS/ASP.net data scenarios

15. Microsoft Visual Studio 2005 Designer Support

16. Additional Features of SQL Ev Runtime enhancements No longer desktop restricted |DataDirectory| macro Dynamically handles location of data files.\Northwind.sdf becomes |DataDirectory|\Northwind.sdf VS Designer enhancements ClickOnce bootstrapper for central installations

17. Deployment Options Single Central Install (MSI) Servicing via Microsoft Update Requires Admin Rights ClickOnce Bootstrapper Private Deployment (ISV Option) Privately deploy the dlls with your application Doesn’t require admin rights No direct servicing by Microsoft App author assumes servicing responsibilities as part of their application

18. Deployment Options ClickOnce with SQL Everywhere Bootstrapper ClickOnce with Private DLL Deployment

19. Privately deploying SQL Ev Central install of SQL Ev will override private version Enables painless deployment ‘till IT rolls out broadly Change System.Data.SqlServer.dll refernce Copy Local Copy sqlce*.dll’s from %ProgramFiles%\Microsoft SQL Server Everywhere\v3.1 Not supported by Microsoft Update Must be serviced by the hosting application

20. Programming Options ADO.NET w/DataSets & Typed DataSets System.Data.SqlServerCe.SqlCeDataAdapter ADO.NET w/DataReaders System.Data.SqlServerCe.SqlCeDataReader ADO.NET w/Updatable Result Sets System.Data.SqlServerCe.SqlCeResultSet ADO.NET Entity Framework (Orcas)

21. SqlCeResultSet No memory caching Think properties w/backing fields as the database Implements Databinding interfaces Dim cmd As New SqlCeCommand() cmd.CommandText = _ "SELECT EmployeeID, LastName, FirstName, " & _ "FROM Employees" cmd.Connection = New SqlCeConnection("Data source = |DataDirectory|\Northwind.sdf") Me.EmployeesBindingSource.DataSource = _ cmd.ExecuteResultSet(ResultSetOptions.Scrollable Or ResultSetOptions.Updatable)

22. SQLCeResultSet ADO.net V3 (Entity Data Model)

23. Securing SQL Server Everywhere Password Protection Database level encryption File system encryption

24. Securing SQL Server Everywhere

25. Summary SQL Server Everywhere is your killer FREE local database Consistent database from device to desktop Consistent data & programming model from device to server Best for synching with SQL Server Base for building Occasionally Connected Systems Start today with Visual Studio 2005 Is the focus for future client database investments
