function Get-DbaDatabaseView {
    <#
        .SYNOPSIS
            Gets database views for each SqlInstance.
 
        .DESCRIPTION
            Gets database views for each SqlInstance.
 
        .PARAMETER SqlInstance
            SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.
 
        .PARAMETER SqlCredential
            Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
        .PARAMETER Database
            To get views from specific database(s) - this list is auto populated from the server.
 
        .PARAMETER ExcludeDatabase
            The database(s) to exclude - this list is auto populated from the server.
 
        .PARAMETER ExcludeSystemView
            This switch removes all system objects from the view collection.
 
        .PARAMETER EnableException
            By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
            This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
            Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
