What about 4th Dimension/4D Server for databases (www.4d.com) as
alternative? REALbasic has a lot of advantages, but I didn't find a
replacement for the fully programmable plug-ins 4D Write (text
processor) and 4D Draw (freely placing and moving any objects,
including database fields, by language AND by the user).
Well, my explanation was incomplete. Mainly, I need to enrich small
apps with
some tables, which store data (logs, messages, menu commands) and
allow an app
to easily read/write/update data.
Here is how it looks for Server Scout's 'Commands' center:
>>>
Dim theKeys () As String
theKeys = Array( "commands.name", "commands.command",
"commands.comtype", "commands.description" _
)
Me.SetDataKeys( theKeys )
Me.SetTableKey( "commands" ) // we read this table
Me.AttachSlaveControl( 0, NameField, "commands.name" ) // client
control will load, update and save automatically
Me.AttachSlaveControl( 1, CommandField, "commands.command" )
Me.AttachSlaveControl( 2, ApplicablePopup, "commands.comtype" )
Me.AttachSlaveControl( 3, CommentField, "commands.description" )
// Attach standard controls
Me.AttachAddButton( AddInvButton )
Me.AttachDeleteButton( DeleteInvButton )
// Me.AttachCloneButton( CloneButton )
// Me.AttachSaveButton( SaveSlaveButton )
Me.AttachCountInfoField( CountInfoField )
Me.AttachHelpText( LagerListHelpText )
// And finally, we need to know the real data model
// Pass 'Me', since I'd like to receive notifications in case the
model changes
Me.SetModel( new TAModelDB_Commands( Me ) )
<<<
This is the complete setup of the UI part of the window.
Additionally, there is TAModelDB_Commands, which is derived from
TAModel_DB, which in turn is derived from TAModel.
TAModel manages the bindings stuff, while TAModel_DB enriches TAModel
with
respect to a 'real' SQL datastore.
Ah: I like MS Access, but never found 4D or Filemaker as attractive.
