You can use TMaps.
Check the help docs and:

Or you can use TLists. It's a bit easier.
I have thrown together a simple example:

SuperStrict ' always use it!

Type TDatabase
	Field dvdlist:TList = New TList
	
	Method AddDVD(nameofDVD:String, publishedyear:String)
		' create a new type
		Local newdvd:TDVD = New TDVD
		newdvd.name = nameofDVD
		newdvd.year = publishedyear
		Self.dvdlist.AddLast(newdvd)		' add new type to list
	End Method
	'
	Method RemoveDVD(nameofDVD:String)
		For Local dvd:TDVD = EachIn Self.dvdlist
			If dvd.name = nameofDVD
				Self.dvdlist.Remove(Self)
			End If
		Next	
	End Method
	'
	Method FindDVD:tdvd(nameofdvd:String)
		For Local dvd:TDVD = EachIn Self.dvdlist ' search whole list for dvd with give name
			If dvd.name = nameofdvd
				Return dvd
			End If
		Next
	End Method
End Type

Type TDVD
	Field name:String
	Field year:String
End Type

' Main

Local mydatabase:TDatabase = New TDatabase ' create a new database
mydatabase.AddDVD("Matrix", "1999") 		' add some data

Local movie:TDVD = mydatabase.FindDVD("Matrix") ' search database for movie Matrix
Print movie.year
