What are the features of remote data objects?


What are the features of remote data objects? We know that RDO allows developers to create interfaces that can openly work together with Open Database Connectivity. I want to know which data access programming model should be used in my client/server application and what are the features of remote data objects?

Characteristics of Remote Data Objects

With RDO and Remote Data control, applications can access ODBC data sources without using a local query processor. This could mean significantly higher performance and more flexibility to access the database engine remotely.

By using RDO, you can:

  • Create simple cursorless result sets or more complex cursors.
  • Run queries and to process any number of result sets.
  • Run stored procedures that return result sets with or without output parameters and return values.
  • Running action queries that perform data manipulation or data definition operations.
  • Limit the number of rows returned or processed.
  • Monitor all messages and errors generated by the remote data source without compromising the execution of the query.
  • Enable asynchronous synchronous or asynchronous processing events so that your application does not crash while running long queries or current record pointer is repositioned.

  • About the Designer user connections: New Microsoft Visual Basic applications is the class design architecture to provide design-time data access programming. You can create a connection and query objects (based on remote data objects) at design time. These connections and queries are stored as objects at the project level. You can preset properties, define new properties and methods, and write the code behind the objects to trap events.

    This provides a simplified method to respond to events generated from the connection sand queries, and to call stored procedures and queries from clients defined at runtime.
