function Get-DbaDatabaseView {
    <#
.SYNOPSIS
Gets database views
 
.DESCRIPTION
Gets database views
 
.PARAMETER SqlInstance
The target SQL Server instance(s)
 
.PARAMETER SqlCredential
Allows you to login to SQL Server using alternative credentials
 
.PARAMETER Database
To get views from specific database(s)
 
.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.
