ISG Navigator also supports chaptered rowsets, scrollable rowsets, and dynasets, even where these features do not exist in the data source. Chaptered rowsets are ones in which a single column from a row of data actually represents a set of rows. This is useful for efficiently retrieving hierarchical data and performing drill down-type data analysis. These features are all part of the extensions to SQL 92 that ISG Navigator supports. The fact that these features can be implemented regardless of the platform or data source is truly amazing.
ADO has only three types of objects and is much simpler to use.
You can use Visual Basic to build an application that uses ADO and ISG Navigator. You can also use Active Server Pages and VBScript to access data sources via a Web browser. By taking advantage of the ASP samples that come with ISG Navigator, I was able to test ADO and database access using my Web browser. I initially had some difficulty getting the example to work, but that was because of my configuration of ADO and had nothing to do with ISG Navigator. After tweaking the code a bit I was able to access my database via Internet Explorer.
