    AI Search Samples

    Just for a moment , I moved away from standard database discussions and thought of writing something about AI.

    I used Indian Airlines as a scenario to demonstrate AI search features.

    Breadth First Search

    Depth First Search

    bullet Simplified. It does do not require configuration or administration.
    bullet Run as a low privileged user.
    bullet Simple installation.
    bullet Offers the same T-SQL language as SQL Server Express. It supports stored procedures,  geometry and geography data types, triggers, views.

    bullet It does not support Windows XP, Windows Server 2003, Window 2000.
    bullet It does not support WOW. LocalDB doesn't support installing 32-bit version on 64-bit Windows.
    bullet Allows only local connections. Only Named Pipes connections.
    bullet Only SQL Server 2012 Management Studio (on a computer updated with .NET Framework 4.0.2) can be used to manage LocalDB. SQL Server Management Studio of previous versions of SQL Server cannot be used.
    bullet Visual Studio 2010 RTM does not support LocalDB.
