Summary

This chapter introduced to you the component of ADO called Remote Data Services or RDS. You have learned that RDS allows client-side applications to access and manipulate data sources through a third middle tier such as IIS. After reading this chapter, you should be able to fully understand RDS and the following key points:

  • There are three objects that make up RDS: the DataSpace object, the DataFactory object, and the DataControl object.

  • The DataSpace object manages the connection through the middle tier to the data source by providing a proxy to the client application.

  • The DataFactory object allows the manipulation and the access to the underlying data source by using the proxy returned from the DataSpace object.

  • The DataControl object is used as a simple way to access a data source through a middle tier without using the DataSpace and the DataFactory objects. This object also allows your client HTML page to be bound to the results of the query that has been executed by the DataControl.
