With CursorAdapter objects, the data source is only a pipe to the translation layer, which renders data from the data source into a Visual FoxPro cursor. Using CursorAdapter class the developer is able to access various data sources in well-known and handy way and easy to switch between different database platforms.Processing data is one of the main purposes of information systems that we develop today. We often need to have our application except accessing native VFP tables to have access to different other data sources as SQL Server, mySQL, Oracle etc. The VFP CursorAdapter class is an excellent resource that helps you to accomplish this.Often it is even necessary for the application to be portable between different database platforms. If you develop on-shelf applications, or you plan to migrate your database in the future, CursorAdapters will assist you to build applications in such a manner, that they can be upsized without the need of rewriting large parts of it.In this session will be demonstrated how to use CursorAdapter objects in your application to access mixed data sources as well as how you can develop easy-to-upsize data access for your applications. In this session we will discuss in dept properties and methods of the CursorAdapter class and how you can use them for better control how your data are retrieved or updated.
