Answer 1

From MS doc: Microsoft Remote Data Service (RDS) allows you to remotely use an ADO recordset using one of three protocols (HTTP, HTTPS, or DCOM). RDS was originally intended for web clients, but you can implement your RDS client in any development environment or language of your choice. You can optionally implement a server-side business object to create and retrieve a set of records, or you can use the default business object that RDS provides in its server components. You must use the Internet Information Server (IIS) to host the RDS server components only when using the HTTP or HTTPS protocols. Using DCOM to marshal objects (records or others) using RDS eliminates the IIS dependency. RDS provides the benefits of client-side data caching,Updated data and support for some ActiveX controls that support data.
